COSEAL NW50 VIT NY66 BK PK1

A centering ring is a flat metal or plastic ring. It fits between two NW flanges. The ring has an O-ring on both sides. The O-rings make the seal.

Viton is a brand name for a type of fluorocarbon rubber (FKM) . It is used in demanding applications.

Here are the benefits of Viton O-rings:

• High temperature resistance: Viton can handle temperatures from -10°C up to 200°C . That is much higher than standard rubber.

• Chemical resistance: Viton resists many oils, fuels, and chemicals. It does not swell or break down easily.

• Low outgassing: In vacuum systems, outgassing is a problem. Materials release trapped gases. Viton has low outgassing compared to many other rubbers.

• Long life: Viton O-rings last a long time. They do not harden or crack as quickly as standard rubber.
