Standard Machined CF Flanges and KF Flanges for Vacuum


Machined CF Flange Introduction:

CF flange is a kind of regular vacuum flange, which is used to connect vacuum chambers, tubing and vacuum pumps to each other. CF is the abbreviation for Conflat Flange. It is a static metal seal. Sealing material is usually Viton, PTFE, and oxygen-free copper. Flange material is generally 304SS, 316SS, or requested by special customers. It can withstand high temperature baking, and the applicable vacuum degree is up to 10-12 mbar, common calibers include: DN16, 40, 63, 100, 160, 200, 250, etc.


Our Machined KF Flange Introduction:

KF flange is also called QF flange, KF is the abbreviation for Quick Flange (QF), and QF is Klein Flange (KF). it is a quick-release flange for vacuum purpose, which is used to connect vacuum chambers, tubing and vacuum pumps to each other. It is easy to disassemble, the main components are: flange, seal ring, centering bracket, clamp. KF Flange material is usually 304 SS, 316SS, etc., and can withstand high temperature baking, the applicable vacuum degree up to 10-8 mbar, common caliber includes: DN 10, 16, 25, 40, 50, etc.

We can make these various types of standard CF Flanges, QF Flange and OFHC copper seal rings with competitive price from prototype to large mass quantity. The materials includes 304SS, 304LSS, 316SS, 316LSS, ESR steel, Aluminum, OFHC copper etc.
