Eaton 3700X6 Brass Female Tee 3/8 Inch Fnptf 1200 Psi

Product Description

The EATON 3700X6 is a brass female tee fitting designed for industrial pipe systems requiring reliable all-female threaded connections. The fitting uses FNPTF (Female National Pipe Taper Fuel) threads on all three ports at a 3/8 inch thread size, allowing straight-through and branch connections in a single component. Rated to 1,200 psi maximum working pressure and a temperature range of -65 degrees F to 250 degrees F, this tee suits demanding fluid and pneumatic service environments. Overall length is 1-5/8 inches. Plumbers, pipefitters, and industrial mechanics are the typical installers.

This fitting is suited for use in residential, commercial, and industrial pipe assemblies where a branch connection is needed without male-threaded adapters. Common applications include fuel, hydraulic, and pneumatic lines where FNPTF thread engagement is specified. Its brass construction makes it appropriate for use with water, oil, fuel, and many common industrial fluids. The 3/8 inch thread size is a standard trade size found across a wide range of pipe and valve assemblies.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable codes such as the IPC or IFGC. Depressurize and drain the system completely before removing any existing fittings or installing this tee. Apply thread sealant or PTFE tape appropriate for the service fluid to all threaded joints. Avoid over-tightening, which can crack brass fittings or distort threads.
