KF25 Flange x 1/8" FNPT vacuum adapter NPT thread stainless steel fitting KF-25
These adapters are KF-25 to 1/8 " NPT Female pipe thread. They are commonly used to make connections between ISO-KF and 1/8" NPT-male pipe. 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 corrosive resistant stainless steel.
