Eaton 140 Drain Cock Shutoff Valve 0.25 Inch Nptf

Product Description

The EATON 140 is a steel internal seat drain cock shutoff valve designed for controlled flow adjustment and system drainage in plumbing and fluid-handling applications. Featuring a 0.25-inch NPTF threaded connection and a brass body construction, this valve provides a reliable seal and durable service in low-to-moderate pressure systems rated up to 150 psi. Its internal seat design keeps sealing components protected from external damage, making it a practical choice for service shutoff and draining tasks. Licensed plumbers and mechanical contractors install this valve during new construction and retrofit work alike.

This drain cock is suited for residential and light commercial plumbing systems where a compact, threaded shutoff or drain point is required. Common applications include water heater drain ports, boiler drain connections, irrigation system service points, and general pipeline drain locations. The 0.25-inch NPTF thread makes it compatible with standard pipe fittings in typical mechanical room and utility installations.

Compatibility

Designed as an OEM-style replacement or new-installation drain cock for standard 0.25-inch NPTF plumbing connections in residential and light commercial fluid systems.

Installation Notes

Installation is performed by a licensed plumber or qualified mechanical technician. Shut off the water supply and relieve system pressure completely before removing or installing any drain valve. Apply thread sealant or PTFE tape to NPTF threads per applicable IPC guidelines to ensure a leak-free connection. Do not overtighten, as brass bodies can crack under excessive torque.
