Vacuum KF Coupling

KF Union (KF Clamp, KF Flanges, KF Centering Ring)

The KF Union is comprised of a KF Clamp, Two KF Flanges, and a KF Centering Ring with Seal.

They can be mated with KF Bored Flages, KF Blanks, and other KF Components.

The easiest way to identify an KF Clamp is its O-ring seal that is supported by a centering ring.

The KF coupling is used in systems where vacuum is present.
