Eaton 1426A Drain Cock Shutoff Valve 3/8 in Nptf

Product Description

The EATON 1426A is a drain cock shutoff valve designed for controlled fluid drainage and flow adjustment in plumbing, HVAC, and industrial piping systems. The valve features an internal seat design with a 3/8 inch NPTF threaded connection and a brass body construction. It is rated to a maximum of 150 psi, making it suitable for low-to-medium pressure service lines. The compact form factor and standard thread size allow for straightforward installation in tight spaces. Licensed plumbers and HVAC technicians install this type of valve on boilers, water lines, and equipment drain points where a reliable shutoff and drain function is required.

The EATON 1426A suits residential and light commercial plumbing and HVAC applications. It is commonly installed on boiler drain ports, water heater drain lines, cooling system drain points, and general-purpose piping where periodic draining or flow adjustment is needed. The 3/8 inch NPTF connection integrates with standard pipe fittings in both new construction and retrofit service work. Its brass body resists corrosion in water service environments, making it a dependable choice for drain points that may see infrequent but critical operation.
