Metal Spherical Joints

Thermionics has supplied stainless steel ball and socket joints to the semiconductor industry since 1978. Connections are made with a ball and socket, an O-ring, and a clamp. These items can be brazed or welded to components or manifolding for difficult curves or adjustable angular connections.

The socket joints are manufactured from type 304 stainless steel to ASTM standards for ground glass joints. They will mate with standard quartz or Pyrex ball couplings and have a vacuum integrity to 5 x 10-9 Torr.

They feature the same ease of assembly as the ISO series, and the same elastomer seals are available on these fittings. There are no metal seals available, however.
