Eaton 108 Drain Cock Shutoff Valve 1/2 Inch Nptf

Product Description

The EATON 108 is a steel external seat drain cock shutoff valve designed for controlled drainage and flow adjustment in plumbing and fluid-handling systems. Built with a brass body and a 1/2-inch NPTF threaded connection, it provides a reliable seal under pressures up to 150 psi. The external seat design allows the valve to be serviced or reseated without full disassembly, making it a practical choice for installations where periodic maintenance is expected. Licensed plumbers and pipefitters install this valve in residential and light commercial applications where a compact, threaded shutoff or drain point is needed.

This drain cock is suited for use in water supply lines, boiler drain points, water heater connections, and similar low-to-medium-pressure fluid systems. The 1/2-inch NPTF thread provides a pressure-tight connection when properly installed with thread sealant or PTFE tape. Its compact form factor makes it appropriate for tight spaces where a full-size ball valve would not fit. This valve handles flow adjustment and shutoff duties in both residential and light commercial plumbing environments.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before removing or installing this valve. Apply PTFE tape or an approved thread sealant to the NPTF threads before making up the connection. Do not overtighten, as brass fittings can crack under excessive torque.
