Our KF Weld Stub Flanges follow ISO-KF standards.
These flanges are ideal for welding onto stainless steel pipework and port tubes.
They are commonly used to build vacuum systems with a vacuum level < 10E-8 mbar/Torr.
They are often called quick flange fittings because they are quick to assemble.
A circumferential clamp and centering ring form the vacuum seal between the connecting flanges.
