KF-40 Bulkhead Feedthrough Adapter, Stainless Steel with Viton O-Ring Seal, for 1" Hole Through, up to 1" Thick.
These bulkhead feedthroughs have a KF-40 fitting. They are used to quickly add an ISO-KF NW 40 port to any flat plate. This bulkhead fitting requires a 1" hole through and can be used on bulkheads up to 1" thick.
The ISO-KF flanges 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 (please see top right figure - click to enlarge). 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 Stainless Steel.
