Stainless steel centering ring assemblies with Viton® O-rings.
High Vauum Centering Ring for ISO (KF, LF) Flanges
Stainless steel centering ring assemblies with Viton® O-rings. These centering rings are used for mating ISO (KF,LF) flanges.
Centering Rings Assembly:
Centering rings are placed between two ISO flanges with matching outer diameters. The tallest part of the stainless steel centering ring rests inside a centering ring locater groove or counterbore. The Viton O-ring rests on the flat polished surface outside the locater groove or counterbore and the vacuum seal is made by compressing the O'ring between the mating flanges. Typically this is done by alternately wrench-tightening opposing pairs of bolts or tightening the hinged clamp until the first metal-to-metal contact is made between the inner surfaces of the flanges and the spacing edges of the centering ring.
Centering Rings Options:
Aluminum or Brass rings on request. Flourocarbon and Buna-N O-rings on request.
