What are some benefits to having Patriot Fluid Power supply your aftermarket seal kits?

Quality Parts

Patriot is committed to supplying the highest quality parts that exceed OEM quality! Our goal is to offer seals and components that are 100% Made in the USA!

Time Savings

Because more and more equipment is manufactured in Europe and Asia, the typical lead time for seal kits is 12-18 weeks, therefore increasing costly down time. Furthermore, you will save man hours by allowing us to measure and create the correct kit for your application.

Cost Savings

In addition to the cost savings from reduced down time, we consistently show our customers a significant savings on the price of the kits.

Aftermarket Sales Income

If you are an OEM (Original Equipment Manufacturer) why not capture all the aftermarket repair parts for your equipment? Patriot will package as well as private label seal kits to your specifications and include only your logo and part number on the kit. We can stock and drop ship for you direct from our warehouse in Freeland, MI.

Please Contact Us to have a member of our technical team assist you with your aftermarket seal kit needs!

Our CJC® Fine Filters are offline depth filters for removal of the most common types of contamination sources: Particle, Water, Varnish & Acid. Built for all sizes of oil systems from ½ gallon to above 53,000 Gallons. CJC filters are installed offline, meaning system shutdown is not necessary when changing filter inserts. All CJC Filter inserts have a 3-micron absolute filtration ratio. They are produced of 100% natural cellulose fibers from sustainable resources – no metal, no plastic, no chemicals!

Remember, in-line filtration alone is insufficient! In-line filtration protects your oil system against larger particles, but CJC offline filters maintain your oil continuously clean and dry, free of also small and harmful particles using a constant pressure and flow. This is the best way to extend the lifetime of components and oil, minimizing breakdowns.

Try it before you buy it!


In addition to the C.C. Jensen 45 day demo, Patriot Fluid Power now has a portable Oil Cleaning Fine Filter available for rental.

HDU 27-27 CC Jensen- Patriot Fluid Power

Our HDU 27/27 unit will clean your oil at a rate of 14.5 gal (55 litre) per hour and is available with the economical General Purpose “A” insert or the High Quality “B” inserts. Both inserts have a 3 micron absolute filtration ratio and particles down to 0.8 micron are retained in the unique CJC® depth filter media.

Maintenance is the largest single controllable expense in a manufacturing plant. With as many as 80% of all machine failures related to contamination in the oil, pro-active methods are saving industries considerable costs every year. Below are some true benefits of Oil Maintenance:

  • Up to 70% less machine stoppages and 60% savings in maintenance costs
  • Increases machine availability = higher productivity
  • Setup costs are quickly recouped (short ROI)
  • Increases lifetime of the hydraulic components
  • Continuous maintenance of the tank (no cleaning necessary)
  • Lower pressure loss and longer lifetime of in-line pressure filters
  • Reduces malfunction and rejects due to higher control accuracy (no varnish layer)
  • Increased lifetime of hydraulic oil
  • Minimizes oil purchase and used oil disposal costs


Contamination can take the form of insoluble materials such as metals, dust particles, sand, and rubber. The smallest particles are often responsible for defects, those below 2 µm, and better known as silt, resin, or oxidation deposits. Dirt holding capacity is the quantity of contamination retained by the filter insert when the saturation pressure is reached. This is measured in weight or volume. How much oil contamination a filter insert is capable of retaining is of highest importance for the cost of operating over a period of time. While most conventional pleated pressure filter inserts can retain less than hundred grams of dirt (<0.2 lbs.), they may be fairly inexpensive to replace. However, if the cost of removing 1 kg or pound of oil contamination is calculated, these conventional pressure filter inserts will suddenly appear quite expensive. A good quality cellulose based offline filter insert can retain up to several kg/lbs. of dirt, so even though the purchase price is higher, the calculated cost for removing one kg or pound of contamination will be considerable lower than that of a pleated pressure filter insert, giving lower lifetime costs.


What is VMI?

(VMI) Vendor managed inventory is an inventory management process in which a Supplier of goods is responsible for the management and optimization of the inventory held by the customer or end-user.

What are the benefits of VMI?

There are several benefits of a Vendor Managed Inventory system (VMI)

  • Patriot Fluid Power dedicates its resources to managing your inventory, so you don’t have to
  • Detailed reports on number of inventory turns – Stocking level accuracy
  • Forecasting and cost analysis reports
  • Elimination of data entry errors through scanning of labels
  • Cost savings due to the elimination of factory minimums
  • Cost savings illustrated by the elimination of down time
  • Elimination of overnight shipping and expediting charges
  • Works with smart phone, no special equipment needed!

Most Common VMI system

One of the most widely used methods of VMI is a 2-bin, Kanban style system. Kanban is a workflow management process designed to help you maximize your efficiency. The primary goal is to reduce costs while creating more value for the customer. The Kanban system utilizes two physical bins with a min and max inventory level assigned by part number. It allows you to manage your inventory critical parts (such as O-rings, seals, custom seal kits, gaskets, etc…). The min and max levels are established by number of turns, the critical assignment and lead time. This is a relatively simple system because the parts are contained in two rotating bins. Parts are pulled which are used to fill orders or provide components to various workstations or departments.

For example, employees pull parts from one bin (front bin) until it is empty. Next, they rotate to the second bin (back bin). They scan the bin label with a phone or other scanning device. Thus, placing an order with Patriot Fluid Power to replenish the inventory in the first bin. This ensures that there is little to no risk of running low or out of stock due to normal usage.

An O-ring, also known as a packing or a mechanical squeeze seal, is a torus or doughnut shaped ring with a round cross-section. They are generally molded form an elastomer such as a rubber compound, however, O-rings are also made from PTFE (Teflon®) and several other thermoplastics as well as metals.

O-rings are one of the most common hydraulic and pneumatic seals used in machinery design due to the fact they are easy to manufacture, are very inexpensive and have relatively simple mounting/installation requirements.


O-rings were first patented May 12, 1896 by Swedish inventor J.O. Lundberg. The US patent was filed by machinist, Niels Christensen in 1937. He used the O-ring as a component in a hydraulic braking system and described it as “a circular section ring . . . made of solid rubber or rubber composition”.

After migrating to the United States in 1891, Christensen patented an air brake system for streetcars. Later the US government commandeered the O-ring patent During World War II and classified it as a critical war-related item thus giving the right to manufacture to other organizations.


O-rings are used primarily for sealing but are also used as a lighter-duty mechanical belt drive. They can be used in static (motionless) as well as dynamic applications (motion between parts). O-rings have been tested in certain applications to seal up to 5000 psi. The maximum sealing pressure of an O-ring will depend on the seal durometer (hardness) and the diametrical clearance between the mating parts.

They have a temperature range between -50f up to +650f for rubber elastomers and as high as +1600f for O-rings manufactured using metal compounds.

O-Ring Applications - by Patriot Fluid Power

Some common applications for O-rings include hydraulic cylinders, pneumatic cylinders, pumps, motors, valves, hose fittings, fluid or gas sealing, vacuum sealing, and many other custom and standard applications.

If you have any questions about o-rings or seals you can contact Patriot Fluid Power anytime.


Hydraulic Seals and Pneumatic Seals

Many seals on the market are interchangeable between hydraulic and pneumatic applications, therefore it is the details of your application that will determine which seal to use. For example, you will need to know your media, pressure, temperature, and speed/velocity.

Hydraulic seals can be made from a variety of materials and durometers such as rubber, fabric reinforced rubber, polyurethane, PTFE, and PTFE blends. The type of material is determined by the specific operating conditions or limits of your system.

Pneumatic seals are predominantly made using a softer elastomer such as rubber. There have been many improvements in materials over the years with new technology creating internally lubricated elastomers for pneumatic applications with little to no system lubrication. Like the hydraulic seals, the type of material is determined by the specific operating conditions or limits of your system.

Two Basic Types of Seals

There are basically two different types of seals, pure lip seal and pure squeeze seal. There are also three basic shapes of seals, round, square and rectangular. Below is an illustration of a lip seal and a squeeze seal in their “free” state as they would appear outside the groove, and how the seal would appear when installed in the groove. Also, an illustration of the three basic seal shapes.

Pure Lip Seal Pure Squeeze Seal comparison brought to you by Patriot Fluid Power

Below is a continuum with pure lip seals on the left where there is low friction, wear and sealability. On the right is pure squeeze seals where friction, wear and sealability are high. The compromise seals in the middle will have varying amounts of friction, wear and sealability.

As we move from left to right on the continuum, we move from simply bending the seal lips to displacing increasing amounts of material. The more material displaced the more mechanical squeeze generated, the greater the sealability but also friction and wear increase. As friction and wear increases seal life decreases.

Seal Types Continuum brought to you by Patriot Fluid Power

In general, most pneumatic seals can be used as a hydraulic seal in applications of lower psi. Conversely, most hydraulic seals cannot be used as a substitute for pneumatic seals due to the hardness of the material. As stated earlier, your specific application will determine which seal is best for you.

If you have any questions about seals you can contact Patriot Fluid Power anytime.



The quick answer, as it relates to seals, is that durometer is the hardness of the seal material, however, there is much more information that is critical when selecting the correct seal for your application. Durometer is more commonly referred to as a Durometer Scale. Although there are several scales of durometer, the two most commonly used scales for measuring the hardness of polymers, elastomers and rubbers, are the ASTM D2240 type A and type D scales.


The Shore hardness standard refers to a measuring device that was developed in the 1920’s by an American metallurgist, Albert Ferdinand Shore. In the case of Shore, his was not the first to measure hardness or to be called durometer, but today the name usually refers to Shore Hardness. Furthermore, there are several other devices and scales used to measure hardness, for instance the Rockwell Scale.


“Durometer, like many other hardness tests, measures the depth of an indentation in the material created by a given force on a standardized presser foot. This depth is dependent on the hardness of the material, its viscoelastic properties, the shape of the presser foot, and the duration of the test. ASTM D2240 durometers allows for a measurement of the initial hardness, or the indentation hardness after a given period of time. The basic test requires applying the force in a consistent manner, without shock, and measuring the hardness (depth of the indentation). If a timed hardness is desired, force is applied for the required time and then read. The material under test should be a minimum of 6 mm (0.25 inches) thick” [1]

The below Hardness scale illustrates a comparison between the Shore A, Shore D and Rockwell R scale and how some measurements overlap each other. For example, a measurement of 90 durometer Shore A is comparable to 40 durometer shore D.

The majority of sealing applications use an elastomeric seal (NBR/Buna, Viton, Silicone, EPDM) ranging in hardness between 70 and 90 Durometer-Shore A. There are several factors within the application that will dictate the durometer of the seal to be used. For example, pressure. Generally, lower durometer seals perform very well in low pressure applications as they produce less resistance to the surface of whatever is being sealed. On the other hand, the higher the pressure the higher the durometer or hardness of seal will be required. In high pressure applications the likelihood of extrusion through the clearance gap increases. (see chart below). Higher pressure combined with higher durometer seals will increase the friction at the sealing point of contact. Many factors must be considered when selecting the proper durometer and seal material. The graph below shows the relationship between pressure, durometer and diametrical clearance (the radial clearance if concentricity between the piston and cylinder is maintained)

Our on-site tech support will do a complete fluid analysis, evaluate your equipment, and recommend the best lubricants, consolidate products, and establish the most cost-effective schedule for use.


Today’s diverse manufacturing processes create decisions required regarding which type of lubricant to use based on overall applications. Predominately, the overall misconception is that a major brand product is the “go to” because of name recognition in the market within the world today. However, even the major brand products can bring obstacles, challenges, and potential increased costs.

For example, availability of material in a timely fashion, high cost of products, price increases given without proper notice. Furthermore, support of product (may take days or weeks to get testing completed or someone to visit). Potential for performance issues (provided a PM program is not in place already). Regardless of the product, issues can arise like how you maintain your car with oil changes every 10,000 miles.

One of our customers was using a major brand grinding oil product for years and thought it was “the best thing since sliced bread.” They had no idea what else existed in the marketplace until Patriot presented them with a high-quality, dependable replacement product. Their first initial reaction was, “Well I’ve been using this product for years, and I don’t believe there’s one that can replace it.” This is a common misconception amongst several manufacturers. Patriot provided a performance-based trial with the customer who responded very favorably.

Stories like this, are why we enjoy working with companies firsthand where we can introduce new products and processes that meet or exceed specifications of a major brand products. Patriot’s clean oil and coolant products can be used with reassurance of our continued support. We do our homework to ensure the switch will be simple and effective.

What are the benefits of our independent blended products?

  • Custom blends to your specifications (synthetic, conventional, or blended) link
  • Generally, cost much less than major brand products
  • Faster availability of products (local inventory)
  • Local service and support
  • Testing and results received within days
  • Easy reordering

What are the ISO Codes and how does it affect your lubricants and clean oil?

The ISO cleanliness code was developed by The International Organization for Standardization (ISO), and is the primary piece of data analyzed at most test laboratories on industrial oil cleanliness reports. The value of each code can help determine the overall cleanliness of your oil/lubricating system. As a result of the analysis, end users will frequently establish a target code (value) to achieve, thus giving them an increased level of confidence if their used oil sample meets or exceeds this established target code.

Automatic Particle Counting (APC) is the most common method used by rest labs when analyzing oil samples for particle counting. When the sample goes through an APC, particles are counted either through pore blockage or laser methods. The laboratories will report the samples particle count micron levels. For example, these various micron levels will commonly include those greater than, 4, 6, 10, 14, 21, 38, 70 and 100 microns.

A typical sample from new bulk oil contains in every 100mL of oil:

Number of particles per 100 ml fluid after their size ranges
More than
ISO Class
450,000 particles >= microns
120,000 particles >= 6 microns
4,000 particles >= 14 microns

How does clean oil affect the life of your component?

The following table is a Life Extension Table – Cleanliness Level, ISO Codes

The table demonstrates the expected increase in the lifetime of components when the oil cleanliness is improved. Each quadrant represents comment/machine type:

  • Top left quadrant is for hydraulic components and diesel engines
  • Top right quadrant is for rolling element bearings
  • Lower left quadrant is for machines incorporating journal bearings, e.g. turbines and turbos
  • Lower right quadrant is for gear boxes and other components not covered by other quadrants
Oil Life Extension table by Patriot Fluid Power
In the table above, for example, the current oil cleanliness in a hydrualic system or diesel engine is found to be ISO 22/20/17 and the oil is cleaned to an ISO cleanliness code of 17/15/12, it can be expected that the lifetime of the hydraulic components is prolonged 4 times.

We can help you fulfill your requirements for the use of funds with the EIDL loan.   

Patriot Fluid Power is made in the USA

Why Buy American Made?

It supports our economy by creating jobs for our friends and neighbors, even yourself!  When you purchase American made products, you are investing money into our economy which grows the manufacturing sector.  As a result, more opportunities are created for our friends and neighbors to provide for their families.  It also builds a better society for the present and future.

American manufacturing

There are so many benefits to American manufacturing. Making products in the United States helps to create a cleaner environment by being more cost effective, saving energy on the delivery, and less pollutive gases are emitted. When products are shipped overseas, a lot of greenhouse gases are discharged and manufacturing in America would then not require for those boats to travel.

Another bonus to manufacturing in the U.S. is that the standards are generally higher than those in other countries, therefore, the quality of the products is typically better. Specifically, the working conditions are better in America, which helps give workers more time and space to do their best work and results in higher quality products. An added benefit that comes of this is that the longevity of the product becomes increased.

Patriot Fluid Power is a proud distributor of several American made products, please contact us for more information.
