Weld Fittings

Weld fittings are drawn and annealed 304 stainless steel tubing, bent and butt-welded to shapes. The weld seams inside crosses and tees are crevice-free to maximize cleanliness for ultra-high vacuum plumbing and process systems. Typical applications for these weld fittings are semiconductor process equipment, specifically, exhaust from a process reactor or roughing piping systems.

Radius Elbows, 45-Degree
Weld vacuum elbows, with and without tangent extensions. The ends are chamfered.
Radius Elbows, 90 Degree
Tube is bent 90 degrees. Choose from radius elbows with and without tangent extensions.
Weld Fittings, 90-Degree Mitered Elbows
Internal passages are smooth, crevice-free butt welds providing maximum cleanliness for UHV applications.
Weld Fittings, 180-Degree Return Bend Elbows
Return weld fittings with chamfered ends, ready to build vacuum plumbing systems.
Weld Tees
Three-way weld tees are butt-welded for maximum cleanliness in UHV applications. Tube ends are chamfered and ready to build vacuum plumbing systems.
Weld Crosses
4-Way, 5-Way, 6-Way weld crosses with smooth, crevice-free internal passages, providing maximum cleanliness for UHV applications.
