Applications

KF flanges are a sexless design made from 304 stainless, they can be used in a wide range of applications including:

* Roughing and foreline plumbing

* Small pipe systems

* Systems need frequent cleaning or modification

* Research and teaching laboratories

Vacuum Range

Elastomer Seal:>=1 x10⁻⁸ Torr

Vacuum Range

Elastomer Seal:>=1 x10⁻⁸ Torr
