DK-LOK DCW-M-P-S Male Pipe Weld Connector

The DK-LOK DCW is a twin-ferrule, gaugeable male pipe weld connector that joins a DK-LOK tube line to a butt/pipe weld end so the fitting can be permanently welded into a pipe system. In the code DCW-M-P-S, the ‘M’ denotes a metric tube OD size designator, ‘P’ denotes the male pipe weld end, and ‘-S’ denotes 316/316L stainless steel. DK-LOK weld ends are constructed to a butt-weld or socket-weld end (per DK-LOK catalog) for weld integrity.

Key Features

Pipe/butt weld end (P) for permanent welded pipe connection
Weld ends built to Schedule 80 or greater
Metric tube OD sizing (M designator)
316/316L stainless steel construction (-S)
