Eaton 1423 Drain Cock Shutoff Valve 3/8 Nptf 150 Psi

Product Description

The EATON 1423 is a drain cock shutoff valve designed for flow adjustment and system drainage in plumbing and fluid-handling applications. Built with a brass body and a 3/8-inch NPTF threaded connection, this valve handles pressures up to 150 psi. The NPTF thread form creates a pressure-tight seal without requiring additional sealant tape in many installations, though standard practice calls for thread sealant per job requirements. At 0.3125 pounds, it is a compact, lightweight valve suited for tight spaces and service work requiring quick drain-and-shutoff capability. Licensed plumbers and pipefitters are the typical installers of this type of valve.

This drain cock shutoff valve is used in residential and light commercial plumbing systems where a dedicated drain point or flow-shutoff is needed. Common installation locations include boiler drain ports, water heater drain lines, irrigation supply lines, and branch shutoffs on supply piping. The valve is rated for 150 psi, making it appropriate for standard domestic water pressure service. It is sold individually and is a direct stock item for plumbing contractors needing a reliable drain cock for service calls or new construction roughin.
