The KF40 to ASA 3.0 Tubular Adapters are made out of stainless steel, without the ring groove. The KF Tubular Assemblies connect the ISO-KF Flange with ASA vacuum fitting. The KF 40 to ASA 3.0 inch 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.
