Sealants for Cryogenic Applications
Sealants for Cryogenic Applications
(OP)
Good morning,
We are looking for a sealant to use with nitrogen at -196 degC for our side channel blowers working at 500mbar. Does anyone know of any such sealant which is suitable? Preferably silicone like to accommodate for expansion.
Thank you

I've also tried non-hardening Permatex which I would NOT recommend (it leaked).

RTV 566 and some by Nusil will meed this type of application
if the gap is small consider Indium seals, they remain compliant at LN temperatures if designed corectly
