DK-LOK DMC-N-S 316 stainless male connector

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

DK-LOK DMC-N-S Male Connector

The DK-LOK DMC-N is a male connector joining a DK-LOK twin-ferrule tube end to a male NPT tapered pipe thread (the -N sub-family designates NPT). The -S suffix is the 316/316L stainless steel build. It is one of the most common DK-LOK fittings, providing a gauge-able, leak-tight tube grip to a standard male pipe port.

Key Features

Twin (two) ferrule tube grip for leak-tight, gauge-able connection
Male NPT tapered pipe thread (N sub-family)
316/316L stainless steel for superior corrosion resistance
Proven back-ferrule design grips across tube wall thickness and O.D.
Available in fractional and metric tube sizes
Can be ordered bored-through for thermocouple use (DMCT variant)
