Atlas Quick-Disconnect Bimetal Fittings seal against tube ODs of standard tubes and enable easy tube joint connections to be made on aluminum vacuum systems. They are made of 6061-T6 aluminum and are available for seventeen US standard tube sizes from 1/16 to 2 inch diameters. Fittings are comprised of four basic parts: a body, gasket, retainer, and nut. The retainer and nut are stainless, and an Atlas bimetallic transition joins the stainless sealing body to the aluminum body for weld-up to an aluminum vacuum vessel. Standard gasket material is a Viton® elastomer, which is capable of sustained operation at temperatures up to 150°C. Quick-Disconnect fittings are a quick and easy way of connecting tubular vacuum components such as feedthroughs, gauges, and glass tubing to aluminum vacuum systems.
