Choosing High Temperature O-Rings

"An ounce of prevention is worth a pound of cure." If you install the wrong o-rings into a high temperature situation, you will be faced with a pound of totally unpleasant and very costly cure.

On first glance, the simple answer is to just install the highest temperature o-rings you can find. But the problem with that is that the higher the temperature range of the o-rings, the more money they are likely to cost. You do not want to waste money paying for more durability than you need.

Of course, in addition to the temperature limits of the materials o-rings are made from, you also need to consider other factors such as chemical compatibility, abrasion resistance, permeability, compression set and tensile strength.

What Happens When O-Rings Get Too Hot

When o-rings are subjected to temperatures beyond their limit for a period of time, the o-rings begin to deteriorate. The volume and compression set of the material is affected. The hardness of the material will change in two stages. In the initial exposure to heat, the elastomer will become softer. If the heat continues, the elastomer will change chemically and the o-rings will harden and lose their elasticity.

Temperature Ranges of Various Elastomers

Neoprene is widely used in o-rings and seals for refrigerators since it is very resistance to Freon and ammonia. It only stands up if the temperature remains under 106° C.

Polyurethane is often used in high pressure systems where the parts are stressed and subject to wear because it has high abrasion resistance and high tensile strength. However, the maximum temperature for polyurethane o-rings is 105° C.

Ethylene Propylene is very resistant to ozone and chemicals and is commonly used in brakes in the automotive industry. It will withstand temperatures up to 135° C.

Nitrile, also known as Buna-N, is the most common elastomer used in o-rings. It resists many oils, fuels, greases, water and alcohol. It has a low compression set, high tensile strength, resists abrasion and is reasonable in cost. It will function up to a temperature of 135° C.

Carboxilated nitrile o-rings will also go up to 135° C while Highly Saturated Nitrile (HSN, HNBR) o-rings will remain intact at 160° C.

Fluorosilicone has high temperature stability and will last up to 200° C. This compound has good resistance to oil, fuels and solvents.

Silicone is good up to 260° C but has limited usage. It works best with hot, static, dry applications.

To move up into the higher temperature ranges for the most demanding applications, it is best to choose either Viton® Fluoroelastomer or Kalrez® Perfluoroelastomer, sophisticated space age materials made by DuPont Performance Elastomers. You might want to look at the information on Viton® and Kalrez® on the Problem Solving Products, Inc. website for more details.

In general, the maximum temperature for continuous operation of Viton® is 204° C and the maximum for Kalrez® is 327° C. There are many grades of Viton® and Kalrez®, each with different characteristics and temperature ranges. It is best to talk to an expert in o-ring design before making a decision about which of these products to use.

This article is to be used only as a general guide and should not be used when making decisions about the design or replacement of o-rings. You will need to consider many factors that are beyond the scope of this article.
