KF Bellows Flex Coupling
ISO-KF Flange Size: NW-16, NW-25, NW-40, and NW-50
Materials: 304 Stainless Steel
Application: Vacuum Equipment
$19.99 – $239.99
KF (also referred to as NW) assemblies consist of two Flanges, a Center-Ring and an aluminum Clamp. Clamps are assembled with wing nuts to insure ease of use over time without tools. A uniform application of pressure on the clamp insures a vacuum seal. The mating flange surfaces compress the O-Ring, which is held in place by a metal centering ring, to generate the vacuum seal.
