Reducer Nipple Weld Fittings

Nor-Cal manufactures its vacuum reducer weld fittings from formed sheet steel. 

These are used to make standard vacuum reducer fittings or to change the diameter of a customer welded foreline or pump installation manifold.

Reducer Nipple Weld Fittings Features

  • ConicaL reducers for smooth transitions with low conductance losses.
  • End cap reducers for simpler straight transitions between tubes of different diameter.
Nor-Cal Products manufactures and provides a full line of flanges, fittings and adapters for vacuum applications. We offer ISO-KF (NW), ISO-K, ISO-F, CF (Conflat), ASA, Wire Seal and EVAC Chain Clamp style flanges and fittings to fit almost every application.
Custom flanges are available upon request.

We specialize in manufacturing components from 304 or 316 stainless steel with several items available in aluminum as well.

We maintain a large inventory for prompt deliveries and to meet those unexpected demands.
