Eaton 1425A Drain Cock Shutoff Valve 1/4 Inch Nptf

Product Description

The EATON 1425A is a steel internal seat drain cock shutoff valve designed for controlled fluid drainage and flow adjustment in plumbing and HVAC systems. It features a 1/4 inch NPTF threaded connection and a 150 psi maximum pressure rating, making it suitable for low-pressure drain and bleed applications. The brass body construction provides corrosion resistance in typical service environments. This valve is installed by licensed plumbers, HVAC technicians, and pipefitters performing drain, purge, or blowdown work on piping systems.

This drain cock is commonly used in residential and light commercial plumbing systems, boilers, water heaters, compressed air lines, and HVAC hydronic circuits where a compact, reliable shutoff and drain point is required. The 1/4 inch NPTF thread allows direct connection to standard pipe fittings without additional adapters in most installations.
