Eaton 3700X2 Brass Female Tee 1/8 Inch Fnptf 1200 Psi

Product Description

The EATON 3700X2 is a brass female tee fitting designed for industrial pipe assemblies requiring a reliable three-way connection. This fitting accepts 1/8-inch female threads on all three ports using the FNPTF (Female National Pipe Taper Fuel) thread standard, which provides a pressure-tight seal without additional sealant compounds in many applications. It is rated for a maximum working pressure of 1,200 psi and handles temperatures ranging from -65 degrees F to 250 degrees F. At 0.08 pounds, the compact brass construction offers corrosion resistance and durability suitable for fuel, hydraulic, pneumatic, and general industrial plumbing systems. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers.

This female tee fitting is suited for residential and commercial plumbing, hydraulic, and pneumatic systems where a tee branch is needed in a 1/8-inch pipe line. Its FNPTF thread classification makes it appropriate for use in fuel lines, air lines, and other pressurized fluid systems. The overall length of 1-1/8 inches keeps the assembly compact, making it practical in tight equipment enclosures or manifold configurations. Plumbing and pipefitting professionals working on industrial equipment, compressors, and small-bore hydraulic circuits will find this fitting a straightforward OEM-style replacement or new-installation component.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC and ASME piping codes. Depressurize and isolate the line completely before removing or installing any fitting. FNPTF threads are designed to seal on the thread form; consult system requirements to determine whether thread sealant tape or compound is appropriate for the specific fluid service. Avoid overtightening, which can crack brass fittings or distort the thread seal.
