Socket Weld Flange

These KF-type socket weld flanges follow KF standards and have different flange sizes from KF-10 to KF-50. They are commonly used to build fore-line vacuum plumbing and process systems. Because they are simple to put together, they are frequently referred to as quick flange fittings. A circumferential clamp and centring ring creates the vacuum seal between the connecting flanges. An O-ring made of rubber elastomer is part of the centring ring. Quick flange fittings come in the following standard sizes: KF-10, KF-16, KF-25, KF-40, and KF-50. They are made up of corrosion-resistant stainless steel.
