Parker DC601-2 Brass Drain Cock Valve 1/8 Inch Nptf

Product Description

The PARKER DC601-2 is a brass male pipe drain cock shutoff valve designed for fluid isolation and controlled drainage in low-pressure piping systems. It features a 1/8-27 NPTF threaded male connection and a maximum working pressure of 150 psi. The brass body provides corrosion resistance in both air and liquid service applications. This valve is installed by licensed plumbers and HVAC technicians wherever a compact, reliable shutoff or bleed point is needed on a small-diameter line. Its lightweight construction — 0.1475 pounds — makes it practical in tight spaces and equipment enclosures.

The DC601-2 is suited for residential and light commercial plumbing, HVAC equipment drain lines, compressed air systems, and hydronic heating circuits. The 1/8-27 NPTF thread size targets small-bore connections common on boilers, air compressors, water heaters, and refrigeration equipment where a manual drain or isolation point is required. Minimum working temperature is 32 degrees F, making this valve appropriate for indoor heated installations. It ships as an individual unit with a package quantity of one.
