O-Rings for NW/KF Centering Rings in Viton®, Silicone and Buna-N

92227-XX V,S,B

Depending on pressure on the O-ring, environment and service temperature, O-rings need to be renewed to ensure leak-free seals. Use the O-rings to service the NW/KF connections on your vacuum systems. O-rings are sold in packages of 10. Viton® O-rings may be black or brown - color cannot be specified.
Viton® is used for high vacuum applications, max. temperature is 250°C
Silicone is used for chemical applications, max. temperature is 220°C
Buna-N is used for non-critical and low vacuum applications, max. temperature is 130°C.

Note: Cross Section Diameter, A=5.3mm (.21") on all O-rings
