Product Questions & Answers

what's the temperature range on this t-seal? got equipment running in some pretty cold conditions and need to know if it'll hold up

Question by: Keith H on Jan 16, 2026, 6:38 PM

Rated from -65°F all the way up to 220°F, so cold-weather operation shouldn't be a problem for most industrial setups. The Buna-N rubber seal handles that range well, and the hard plastic back-up rings help maintain the seal shape under pressure swings that come with temperature changes.
