NW flanges utilize an aluminum clamp with a single wingnut fastener allowing frequent disassembly without tools. The vacuum seal is effected by uniform application of pressure by the clamp on the 15° surface of the 304 stainless steel flanges. The mating flange surfaces compress a Viton® O-Ring held in place by a centering ring. Nor-Cal offers aluminum and stainless steel centering rings for NW flanges with Buna, silicone and Viton® O-rings.
