The EATON 6749 is a three-way shutoff drain cock valve designed to control and drain fluid flow in low-pressure plumbing and fluid systems. The brass body provides corrosion resistance suitable for water and light fluid service. With a 1/4-inch thread connection and a 30 psi maximum pressure rating, this valve is sized for small-diameter lines where a compact, reliable shutoff and drain function is required. Licensed plumbers and mechanical contractors install this type of valve in residential and light commercial piping systems.
The 6749 fits applications where a single valve must both shut off flow and allow a system section to be drained without removing additional fittings. Typical install scenarios include boiler drain points, test cocks, and low-pressure fluid panel drain lines. The compact form factor makes it practical in tight spaces where a standard ball valve and separate drain fitting would not fit.
Designed as an OEM-style replacement or new-installation drain cock for low-pressure residential and light commercial plumbing systems using 1/4-inch threaded connections rated at 30 psi or below.
Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off system pressure and drain the line fully before removing or installing any drain cock or shutoff valve. Apply appropriate thread sealant or PTFE tape to male threads before assembly, and verify the system does not exceed the 30 psi rated working pressure of this valve after installation.
