Parker V407P-4 Brass Drain Cock Shutoff Valve Nptf

Product Description

The PARKER V407P-4 is a brass female pipe drain cock shutoff valve designed for fluid control and manual drain applications in plumbing, HVAC, and industrial piping systems. It features a 1/4-18 NPTF threaded connection and a maximum working pressure of 30 psi. The compact brass body provides reliable sealing performance across a wide temperature range. Licensed plumbers and HVAC technicians install this type of valve as a drain point or manual isolation fitting in low-pressure piping runs. The NPTF thread form creates a pressure-tight seal without relying solely on thread sealant.

This drain cock valve suits residential and light commercial applications where a manual shutoff or drain point is needed on a low-pressure line. Typical uses include boiler drain connections, compressed air manifold drains, water supply branch lines, and equipment service ports. It is appropriate for systems where a compact, inline manual valve is required at a 1/4-inch pipe fitting location.

Key Features

• NPTF 1/4-18 female pipe thread for a pressure-tight mechanical seal
• Brass body construction for corrosion resistance in water and air service
• Rated to 30 psi maximum working pressure
• Wide temperature range down to -40 degrees F for cold-climate installations
• Compact form factor fits tight plumbing spaces and equipment panels

Compatibility

Designed as an OEM-style replacement or new-installation drain cock for low-pressure plumbing and HVAC piping systems using 1/4-18 NPTF female pipe thread connections rated at or below 30 psi.

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 and depressurize the system completely before removing or installing any valve. Apply an appropriate thread sealant or PTFE tape to the male fitting threads before making up the NPTF connection. Do not exceed the 30 psi maximum working pressure rating for this valve.
