DK-LOK DMAA-S 316 stainless male AN adapter

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

DK-LOK DMAA-S Male AN Adapter

The DK-LOK DMAA is a male AN (Army-Navy) 37-degree flare adapter that joins a DK-LOK twin-ferrule tube connection to a male AN flare port. The DMAA-S designation is the 316/316L stainless steel build, providing superior corrosion resistance in chloride, sulfide, and acid service. It mates the gauge-able twin-ferrule tube end to an AN flare fitting commonly used in fluid power and instrumentation systems.
