Overview
The KF Vacuum Hose Couplings are available in the following sizes: NW 16, NW 25, NW 40, and NW 50.
The KF 40, NW 40 Vacuum Hoses are available in the following lengths: 250 mm, 500 mm, 750 mm, and 1000 mm.
The Flexible KF-40 Hose Couplings (Also known as Flexible Bellows) are made out of 304 Stainless Steel.
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.
