NOR CAL PRODUCTS INC NW-50 Stainless Centering Ring with Screen
Supplier: NOR CAL PRODUCTS INC NW50CRSV74

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 FKM O-Ring held in place by a centering ring. Nor-Cal Products offers aluminum and stainless steel centering rings for NW flanges with Buna, silicone and FKM O-rings.
