KF-50 clamps, also called QC (quick connect) or QF (quick flange) clamps, are used to connect KF-50 flanges wherever KF-50 vacuum lines meet, including pump connections, valves, chambers and process lines. LoCo Science carries KF-50 clamps in both 304 stainless steel and aluminum. All LoCo Science clamps are sold as a set with a 304 stainless centering ring and Viton gasket in the package.
Which KF-50 clamp do I need?
- Join two KF-50 flanges: One KF-50 clamp and centering ring set per joint.
- Replace a worn centering ring: Spare rings are on the KF Centering Rings page.
Frequently asked questions
Does the KF-50 clamp come with a centering ring?
Yes. Every LoCo KF-50 clamp is sold as a set with one KF-50 centering ring.
Is a KF50 clamp the same as an NW50 clamp?
Yes. KF50 and NW50 are two names for the same size, so this clamp fits flanges labeled either way.
