Parker V402P-4-4 Drain Cock Shutoff Valve Nptf

Product Description

The PARKER V402P-4-4 is a brass drain cock shutoff valve with a female-to-male pipe configuration, designed for manual drainage and flow isolation in low-pressure plumbing and fluid systems. The valve connects via 1/4-18 NPTF threads and carries a maximum working pressure of 30 psi. Weighing just 0.1775 pounds, it is a compact, lightweight fitting suited for tight installation spaces. Licensed plumbers and HVAC technicians install this valve type to provide controlled drain points on equipment, piping runs, and compressed-air or fluid circuits.

This drain cock is appropriate for residential and light commercial plumbing, HVAC condensate and fluid circuits, and compressed-air systems where a serviceable drain point is required. The female-to-male pipe connection allows it to thread directly into a pipe end or tee fitting, providing a removable drain or purge point. Its brass construction offers reliable performance in potable and non-potable water, as well as compatible fluid applications. The 1/4-18 NPTF thread creates a pressure-tight mechanical seal without relying solely on thread sealant.

Key Features

• 1/4-18 NPTF thread size for a pressure-tight mechanical seal
• Maximum working pressure of 30 psi
• Brass body construction for corrosion resistance in water and compatible fluid service
• Female-to-male pipe configuration for direct in-line or tee installation
• Compact and lightweight at 0.1775 pounds for use in tight spaces

Compatibility

Designed as an OEM-style replacement or service fitting for 1/4-18 NPTF drain cock applications in low-pressure plumbing, HVAC, and compressed-air systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and the IPC. Shut off the fluid supply and relieve system pressure completely before removing or installing this valve. Apply thread sealant or PTFE tape to the male threads as appropriate for the service fluid. Do not exceed the 30 psi maximum working pressure rating.
