Nor-Cal Products manufactures a complete selection of 304 or 316 stainless steel vacuum line hardware. Choose from more than 2,500 flanges, fittings, adapters, and transitions. Flange types include NW (ISO-KF), ISO, CF (Conflat), ASA and wire seal as well as chain clamps and aluminum seals for converting NW and ISO flanges from high vacuum to UHV. Aluminum/stainless steel transitions are used with standard CF flanges for UHV sealing and have the ability to provide value-added, custom designed vacuum-line assemblies in a variety of configurations and sizes. For applications that require heating, Nor-Cal Products can provide heater jackets and insulators for any of our valves or vacuum line components. 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. Most standard parts can be customized to meet your requirements.
