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

DK-LOK DLSW-B Tube Socket Weld Elbow (Brass)

The DK-LOK DLSW is a twin-ferrule, gaugeable tube socket weld elbow that connects a tube line to a tube socket weld end at an angle, allowing the fitting to be socket-welded into a tube/pipe system. The tube side uses DK-LOK’s two-ferrule gaugeable design. The ‘-B’ suffix designates brass; note DK-LOK lists DLSW socket weld ends as applicable for SS316 and carbon steel up to 1/2 in. (-8), so brass availability should be confirmed with DK-LOK before ordering.
