Reducer Crosses Weld Fittings

Pfeiffer manufactures its vacuum cross weld fittings from tubing either through the pulled-port or bore-and-cope technique.

These are used to make standard flanged fittings as well as build-to-print custom manifolds where 90-branches of the same or a different diameter is required.

Pfeiffer 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. Centering rings, gaskets, clamps, bolts and other hardware components are available to complete your project. We maintain a large inventory for prompt deliveries and to meet those unexpected demands.
