Piston Seals
Sealing ring: F-PTFE
Elastomer: NBR or FKM
Share:
Application Range
This is a kind of standard combined seals used in large scale applications, and it has the same performance with SPG.
Please refer to standards of SPNO series of NOK Company, TFMA series of Merkel Company and YL series of AS Company when designing and selecting.
Features
The used sliding material is filled with PTFE, and such seals have very low friction resistance and can eliminate crawling and guarantee high abrasion resistance. Since single seal has bidirectional sealing capability, the installation space can be eliminated.
