Atlas Socket Weld, Butt Weld, Male Weld, and Chamber Mount ATCR™ face-seal fittings are fitted with a durable stainless steel sealing face that is explosion welded (EXW) to an aluminum body. The bond produced is extremely rugged. All face-seal fittings are helium leak tested for service in UHV environments in excess of 1×10-9 Torr. Atlas ATCR™ fittings enable robust, demountable use of aluminum tubing in cryogenic, physics, and semiconductor applications worldwide. Standard Socket, Butt, Male and Chamber Mount geometries are available in 1/4, 3/8, 1/2, 3/4 and 1 inch tube diameters. Chamber Mount fittings are available in four length configurations suitable for 1/2, 3/4, 1 and 1-1/4 inch chamber wall thicknesses.

Atlas ATCR™ fittings are fully compatible with Swagelok VCR® and Parker-Hannifin VacuSeal® fittings. Unlike these other fittings, however, Atlas ATCR™ fittings are used where high thermal conductivity and high chemical resistance is needed or where any of the advantageous physical properties of aluminum are required.

Atlas bimetallic ATCR™ fittings: the aluminum tube fitting with a stainless steel face-seal that makes UHV aluminum vacuum systems a reality.
