Problem Solving Products, Inc.

O-Rings and Seals

Our specialty is solving sealing problems for original equipment manufacturers. Please contact us at (303) 758-2728 if you need help with a sealing problem or design.

We carry o-rings, seals, custom molded rubber parts, wipers, diaphragm, valves and u-cups in all types of materials including Viton®, Kalrez®, Viton® Extreme™ ETP, Simriz®, nitrile (buna-n), neoprene, rubber, silicone, polyurethane, TFE and FEP encapsulated elastomers.

We are certified to sell Viton®, Kalrez® and Viton® Extreme™ ETP by DuPont.

our procedures are impeccable

We focus on establishing long-term relationships and exceeding our customer expectations.


Viton® o-rings and seals Viton® and Viton® Extreme™ ETP O-rings and Seals

Viton® fluoroelastomer has excellent (400°F/200°C) heat resistance and is very resistant to aggressive fuels and chemicals. There are four families of Viton® polymers: A, B, F and Viton® Extreme™ ETP.


KalrezKalrez® O-rings and Seals

Kalrez® resists over 1,800 different chemicals while offering high temperature stability (600°F/316°C). It is used in highly aggressive chemical processing, semiconductor wafer processing and other demanding sealing applications.


elastomers for o-rings and sealsElastomers for O-rings and Seals

Choosing the right elastomer for your application is very important. If you are not careful you can choose the very best, such as a Viton® Extreme™ seal or Kalrez® o-ring, when a cheaper elastomer would actually work better.


elastomer propertiesElastomer Properties

The proper o-ring and seal design depends on a knowledge of many elastomer properties such as hardness, tensile strength, compressive response, compression set, stress relaxation, abrasion resistance and tear resistance.


seal design theory Seal Design Theory

The use of an o-ring as a seal is mainly to prevent the transfer of fluid (liquid, solid or gas) between two or more regions. Successful seal design ensures adequate seal compressive force while minimizing the destructive stress acting on the o-ring.


o-ring and seal failure analysis Seal Failure Analysis

O-rings and seals fail for many reasons. It is useful to analyze the environment, seal design and elastomer when there is a failure. Problem Solving Products, Inc. helps manufacturers correct problems with sealing failures.



Fluid Compatibility Fluid Compatibility Charts

Before designing an o-ring or seal, it is important to know how compatible the elastomer is with all the chemicals that will contact it.

o-ring cord PSP O-ring Sizes

PSP o-ring sizes are the same standard sizes used throughout the o-ring industry and in most aerospace and military applications. We stock all standard sizes and many non-standard and metric sizes. We can manufacture any o-ring size to your specifications.


we serve many industries Industries We Serve

PSP supplies products to every industry including food processing, chemical processing, semiconductor, pharmaceutical and the automotive industry. We can supply a small number of specialized o-rings for a research design project or a huge quantity to original equipment manufacturers.


product information Product Information (partial list)

We carry products in all materials including Viton®, Kalrez®, Viton® Extreme™ ETP, Simriz®, nitrile (buna-n), silicone, rubber, neoprene, polyurethane, TFE and FEP encapsulated elastomers. We have all sizes and shapes, everything from x-rings to u-cups.


Problems Solved

We solve problems by analyzing each individual application in depth. The seal design is critically important and it must be sized right. Otherwise, the seal will fail, perhaps with disastrous results. This was the case with train that that leaked oil and started fires all along the track.

News Releases from Dupont on the latest Viton® and Viton® Extreme™ ETP research plus information on Expositions and Conferences for engineers that are scheduled for the future.


Metal detectable elastomer material for an o-ring or sealMetal Detectable O-rings and Seals

In the food and beverage industry, a piece of elastomer can break off from a seal due to excessive wear or improper installation and contaminate the product. Metal detectable o-rings and seals are an efficient and cost effective way to handle this problem. Fragments as small as 2 mm can be identified by metal detector equipment. The tainted product can be immediately segregated from the process stream.
