Eaton 703 Straightway Drain Cock Shutoff Valve 3/8 in

Product Description

The EATON 703 is a straightway drain cock shutoff valve designed for low-pressure fluid control and drainage applications in plumbing and mechanical systems. It features a 3/8-inch tube connection and a 1/4-inch thread size, with a maximum working pressure rating of 30 psi. The valve body is constructed of brass, providing corrosion resistance suitable for water and light fluid service. Licensed plumbers and mechanical contractors install this type of valve where a simple, reliable drain point or flow-adjustment shutoff is required. Its compact, straightway design allows for clean inline installation with minimal flow restriction.

The EATON 703 drain cock is suited for residential and light commercial plumbing applications where a dedicated drain or shutoff point is needed on low-pressure water lines, boiler drain connections, or equipment service ports. The straightway configuration makes it a practical choice for installations requiring a direct flow path with quick manual shutoff capability. It is appropriate for use on copper tube systems where a threaded valve connection is required at a service or drain location.
