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.
