- 2. Material The material used to manufacture the 14x22x5 oil seal can vary depending on the application requirements. Common materials include nitrile rubber, fluoro rubber, and silicone rubber, each with its own unique properties such as temperature resistance, chemical resistance, and compression set.
Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.

The temperature range of the mechanism in which the seal is installed must not exceed the temperature range of the seal elastomer.
