Parker V402P-6-6 Drain Cock Shutoff Valve 3/8 in Nptf

Product Description

The PARKER V402P-6-6 is a brass drain cock shutoff valve designed for controlled fluid drainage and flow shutoff in plumbing and HVAC piping systems. It features a female pipe inlet to male pipe outlet configuration with a 3/8-18 NPTF thread connection, rated to a maximum working pressure of 30 psi. The all-brass body provides corrosion resistance in wet service environments. This valve is installed by licensed plumbers and HVAC technicians where a compact, reliable drain or isolation point is needed on a 3/8 inch pipe run.

The V402P-6-6 is suited for residential and light commercial applications where a shutoff or drain point is required on a 3/8 inch NPTF-threaded line. Common install scenarios include HVAC condensate lines, boiler drains, compressed air piping, and general plumbing drain ports. The female pipe to male pipe end configuration allows direct in-line installation without additional adapters in standard threaded pipe assemblies. Minimum working temperature is 32 degrees F, making this valve appropriate for indoor heated-space piping where freeze exposure is not a concern.

Key Features

• Brass body construction resists corrosion in wet service applications
• 3/8-18 NPTF threaded connections provide a pressure-tight, dryseal fit
• Female pipe inlet to male pipe outlet for straightforward in-line installation
• 30 psi maximum working pressure rating suitable for low-pressure drain and shutoff service

Compatibility

Designed as an OEM-style replacement or new-installation drain cock shutoff valve for 3/8-18 NPTF threaded pipe systems in residential and light commercial plumbing and HVAC applications.

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 water or fluid supply and relieve all system pressure before removing or installing this valve. Apply thread sealant or PTFE tape to the male threads as required by local code to ensure a leak-free NPTF connection. Do not exceed the 30 psi maximum working pressure rating or install in systems subject to freezing conditions.
