Description:
Bellows Hose Metal Flex Coupling vacuum fittings follow ISO-KF Standards 304 Stainless Steel
These KF-16/KF-25/ KF-40/KF-50 Bellows Flex Coupling vacuum fittings follow ISO-KF standards and have a flange size NW-16/ NW-25/NW-40/NW-50.
They are commonly used to build foreline vacuum plumbing and process systems.
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. The centering ring contains a rubber elastomer o-ring.
The standard sizes for quick flange fittings are KF-10, KF-16, KF-25, KF-40, and KF-50 with flange sizes NW-10, NW-16, NW-25, NW-40, and NW-50, respectively.
They are made of corrosive resistant stainless steel.
