Technical Design Considerations

Stretching
The maximum stretching of Cryolox seals should never exceed 4%. Stainless encapsulated seals are more suited for O.D. applications where stretching the diameter is limited.

Installation
The stainless steel spring has resilience but it should not be over compressed into the groove. Compression guidelines are listed below.

Venting
When stainless seals are exposed to pressures greater than 1300 PSI, they should be vented to prevent bursting of the encapsulation. Three vent holes are placed at a predetermined location in the FEP or PFA jacket.

Cryogenic seals are made with stainless precision rolled strip steel with special tolerances, encapsulated in an FEP or PFA jacket.

Cryolox maintains its resilience when exposed to cryogenic temperatures, and offers superior face seal properties in extremely low temperatures.
