Swagelok SS-1VS8 316 stainless steel integral bonnet needle valve with black phenolic knob, 1/2 inch Swagelok tube fitting

DK-LOK DLW-P-S Male Pipe Weld Elbow

The DK-LOK DLW is a twin-ferrule, gaugeable male pipe weld elbow that connects a tube line to a male pipe (butt) weld end at an angle, allowing the fitting to be welded into a pipe system. In DLW-P-S, the ‘P’ denotes the male pipe weld end and ‘-S’ denotes 316/316L stainless steel. The tube side uses DK-LOK’s two-ferrule gaugeable design; DK-LOK weld ends are built to a butt-weld or socket-weld end (per DK-LOK catalog).
