Fittings for Stainless Steel Tubing Create access points in ultra-high-vacuum lines or chambers by bolting two same-size flanges together with a copper gasket between them. The flanges sharp edges dig into the copper gasket and form an extremely tight seal, which means they handle higher vacuum pressures than other high-vacuum fittings with rubber gaskets. Butt-welding pipe fittingsused for stainless steels, and decided to reflect these in the standard by differentiating between two parts, Part 3 and Part 4. Part 4 defines two types of fittings:Type A fittings have the same wall thickness at the welding ends than a pipe having the same specified wall thickness.Stainless Steel Butt Weld Pipe Fittings - Grainger Cover or close the end of a stainless steel pipe with these butt weld cap fittings.
