Silicone rubber O-rings are the most popular material choice because they’re capable of performing in a wide range of temperatures without melting or hardening. However, silicone rubber does have its limits. The average temperature range for silicone rubber O-rings is between -62 and 204 degrees Celsius.

O-rings can additionally be manufactured to custom sizes. Materials outlined below include Nitrile (NBR), Viton® (FKM), EPDM, Hydrogenated Nitrile (HNBR), 

Due to many applications, there is also a wide variety of O-ring material choices available. Nitrile (Buna), Neoprene, Ethylene Propylene (EPDM Rubber), Silicone, Fluorocarbon (Viton), and PTFE (Teflon) are among the most commonly used compounds for O-rings and seals.

Some of the benefits of rubber O rings are how easy they are to manufacture, their low cost, reliability, pressure resistance, and ease of mounting. They are 

Our most popular O Ring Material is Nitrile (NBR) 70° Shore 'A'. This is an Elastomer seal that can do the majority of standard industrial applications.

Rubber O-rings, when not properly lubricated, can fail due to abrasion or pinching. Using an oil- or grease-based lubricant helps protect the surface of the O-ring and can prevent degradation of the elastomer material. This will prevent failure and help extend the life of your O-ring. Request a quote on custom AS568 rubber O-rings, or contact

One type of O-ring material. Image credit: krolya25/Shutterstock.com. O-rings are a form of gasket or seal that features a round cross-section. They are commonly used to prevent leaks of either fluids or gases from occurring in products, systems, or machinery and find use across a variety of industries.

Size. Choose the appropriate size based on the size of the mating surface's groove—both diameter and the groove's width—and the flexibility of the material. Surface finish. O-rings should fall within a tight surface roughness range of 5-16 µ inch RMS to minimize the risk of friction or accelerated wear.
