Application Range
Sealing ring: F-PTFE Spring energized seals for shaft is a kind of sealing used for reciprocating motion of internal sealing. This kind of seal can be applicable for poor working conditions and also be adapted to the requirements of certain special mediums. JRVA sealing is the recommended sealing to use for the requirement of no crawling, chemical resistance and resistance of most mediums, such as valve, pump, separator, brake and batching apparatus.
Please refer to the standards of RVA series of Trelleborg Company and JS series of Parker Company when designing and selecting.
