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.
