Parker V403P-2-2 Drain Cock Shutoff Valve 1/8 in Nptf

Product Description

The PARKER V403P-2-2 is a brass drain cock shutoff valve with female pipe to female pipe connections on both ends. It is designed for draining or isolating fluid lines in plumbing and fluid-handling systems where a compact, low-pressure manual valve is required. The valve uses NPTF threads sized at 1/8-27 and is rated for a maximum working pressure of 30 psi. The all-brass body provides corrosion resistance suitable for water and light-duty fluid service. Plumbers and HVAC technicians commonly install this type of valve at low points in piping systems, boiler drain ports, and condensate or equipment drain lines.

The V403P-2-2 is suited for residential and light commercial plumbing applications where a small-bore manual drain or shutoff point is needed. Typical installations include boiler blowdown ports, compressed air drain points, hydronic system drain-downs, and equipment isolation points. The 1/8-27 NPTF thread size makes it appropriate for small-diameter pipe connections in tight spaces. The valve is packaged individually and ships as a single unit.
