Butt-Weld Fittings for Stainless Steel Tubing
- For Use With: See table
- Max. Temperature: 250° F, except hose fittings are unrated.
- Tubing:
304 Stainless Steel: Use with 304/304L stainless steel that meets ASTM A213, ASTM A269, or ASTM A270, except DIN EN 10357 fittings with only ASTM A269 or ASTM A270
316 Stainless Steel: Use with 316/316L stainless steel that meets ASTM A213, ASTM A269, or ASTM A270, except ASME BPE and DIN EN 10357 fittings with only ASTM A269 or ASTM A270 - Specifications Met: See table
Weld these fittings to tubing for a permanent, flush connection that permits smooth flow through a line.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

High-Pressure Socket-Connect Fittings for Stainless Steel Tubing
- For Use With: Air, Hydraulic Fluid, Water
- Temperature Range: -420° to 1200° F
- Tubing: Use with welded or seamless 304 or 316 stainless steel that meets ASTM A269
These socket-connect fittings have the strength to handle high pressures up to 4,300 psi. Easier to weld than butt-weld fittings, they don’t need to align perfectly to tubing. Insert tubing into the socket end and weld to create a permanent, leak-tight connection. Fittings are 316 stainless steel for excellent corrosion resistance.
