Parker V401P-4-4 Drain Cock Shutoff Valve 1/4 in Nptf

Product Description

The PARKER V401P-4-4 is a male pipe to male pipe drain cock shutoff valve designed for controlled drainage and fluid shutoff in low-pressure piping systems. Built with a brass body, this valve accepts 1/4-18 NPTF threaded connections on both ends and is rated for a maximum working pressure of 30 psi. At 0.1965 pounds, it is a compact, lightweight fitting suited for plumbing, compressed air, HVAC drain lines, and similar applications where a reliable manual shutoff or drain point is needed. Licensed plumbers and HVAC technicians install this type of valve as a service drain or isolation point in small-diameter piping runs.

This drain cock is appropriate for residential and light commercial applications involving small-bore piping. It fits inline or at terminal drain points in systems carrying water, air, or compatible fluids at or below 30 psi. The NPTF thread form provides a pressure-tight mechanical seal without relying solely on thread sealant. Typical install locations include boiler drain ports, compressed air lines, HVAC condensate circuits, and similar low-pressure fluid systems where periodic manual draining is required.

Key Features

• Brass body construction for corrosion resistance in water and air service
• 1/4-18 NPTF threads on both male pipe ends for a pressure-tight mechanical fit
• 30 psi maximum working pressure rating
• Compact and lightweight at 0.1965 pounds
• Manual drain cock design for straightforward open and close operation

Compatibility

Designed as an OEM-style replacement or new-installation drain cock for small-diameter male pipe threaded systems using 1/4-18 NPTF connections rated at or below 30 psi.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician. Isolate and depressurize the system completely before removing or installing any valve. Apply thread sealant tape or compound appropriate for the service fluid to the male NPTF threads before assembly. Tighten to hand-snug plus wrench-tight following standard pipe fitting practice and verify for leaks after restoring system pressure.
