The KF-40 to ¼ NPT female pipe thread adapters are made out of stainless steel and are used to connect the ISO-KF flange with the male pipe. The KF 40 to ¼ inch NPT-Female Adapter assemblies consist of two flanges, a centering ring, and an aluminum clamp. 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 vacuum seal.
