Gasket designed for cryogenic sealing of liquified gasses

Gaskets in cryogenic applications face extremely challenging conditions as the environment is very cold, materials become brittle, expansion / contraction rates of the joint differ and cryogenic gasses are atomically small and therefore difficult to seal. Our line of Revoseal semi-metallic croygenic gaskets are designed to have lowest leak rate possible even for the most challenging liquified gasses such as hydrogen, helium, nitrogen, argon, oxygen, carbon dioxide and LNG (liquified natural gas). 

Specialty Materials

All of the Revoseal gaskets can operate at cryogenic temperatures and are constructed from a stainless steel with a PTFE or graphite soft seal design. Specialty alloys like nickel alloys can be utilized in our JG / JP gaskets for improved ductility. 

Thermal Expansion

When thermal expansion or contraction is a problem as a process thermally cycles, the Revolution gasket is ideal as it acts like spring and dynamically responds to expanding or contracting joints.

Material Compression

All the Revoseal cryogenic gaskets require a very low sealing force when compared to graphite or spiral wound gaskets and will not over-compress like PTFE or graphite, due to the metal-to-metal seal in combination with a PTFE / graphite soft seal. This metalic seal protect the PTFE & graphite from being over-compressed and becoming brittle.
