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.
