NW Flanges-Image

Nor-Cal NW flanges are designed to ISO 2681 specifications for standard USA tube sizes from .375 to 2.00 inches. They are compatible with other manufacturers' ISO-KF style flanges. 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. The resultant seal can be used in vacuum applications of up to 10-8 Torr and baked to 204°C, however sustained baking above 150°C may result in deterioration of O-rings. Nor-Cal offers aluminum and stainless steel centering rings for NW flanges with Buna, silicone and Viton® O-rings.

Additionally, Nor-Cal's NW flanges have the advantage of being rotatable and are available on virtually all of our components and fittings. Nor-Cal manufactures a full line of NW adapters so you can add to or build an entire system with NW components.

NW flanges can also be used with EVAC chain clamps and aluminum seals to obtain a UHV seal bakeable to 150°C.
