Flanges

Conflat flanges (CF) are designed to enable affordable, repeatable seals, that have low leak rate and the ability to withstand the high temperatures used for de-gassing (up to 450°C) without leaking. Our range of UHV flanges are fully compatible with the internationally agreed standards and will connect to any other compliant CF flange. Available, as standard, in 304L and 316LN ESR.
