Parker DC601-8 Brass Drain Cock Shutoff Valve Nptf

Product Description

The PARKER DC601-8 is a brass male pipe drain cock shutoff valve designed for controlled fluid drainage in plumbing, HVAC, and industrial piping systems. Built with a brass body for corrosion resistance and durability, it features a 1/8-27 inch NPTF threaded connection and a maximum working pressure rating of 150 psi. The valve is used to isolate and drain sections of a piping system during service, maintenance, or winterization procedures. It is installed by licensed plumbers, HVAC technicians, and pipefitters working on both residential and light commercial systems.

The DC601-8 is suited for low-pressure fluid service lines where a reliable shutoff and drain point is required. Typical applications include boiler drain points, water supply shutoffs, and service drain locations on hydronic heating systems, domestic water lines, and compressed air circuits. Its compact brass construction makes it a practical choice for tight spaces where a dependable manual shutoff valve is needed.
