Stainless steel gaskets are required in certain gas systems such as carbon monoxide, ozone, and trimethyl arsenic.
Because SS gaskets are harder than nickel, the torque induced problems of sealing and galling are amplified.
Due to the SS sealing problems, some companies have specified silver plated SS gaskets to reduce friction and galling. Recently these gaskets have been identified as a source of silver contamination.
Omnisafe torque elimination fittings can be used safely and securely with polished SS gaskets. There is no particle generation.
