DK-LOK DL 90 degree twin-ferrule union elbow

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

DK-LOK DL Union Elbow (90°)

The DK-LOK DL is a twin-ferrule, gaugeable union 90 degree elbow that connects two tube lines of the same outside diameter at a right angle. Both ends use DK-LOK’s two-ferrule gaugeable tube-grip design for leak-tight mechanical seals. The base ‘DL’ code does not specify a material; DK-LOK offers it in 316 stainless steel, brass, and carbon steel (material is set by the suffix, e.g. -S for stainless, -B for brass).
