Eaton 3700X4 Brass Female Tee 1/4 Inch Fnptf 1200 Psi

Product Description

The EATON 3700X4 is a brass female tee fitting designed for industrial pipe systems requiring reliable, leak-free connections at high working pressures. Threaded to the FNPTF standard in a 1/4 inch female configuration, this tee allows a single inlet to split into two outlet paths — or vice versa — within plumbing, hydraulic, pneumatic, and fluid transfer assemblies. It carries a maximum working pressure of 1,200 psi and handles a temperature range from -65 degrees F to 250 degrees F, making it suitable for demanding service environments. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers.

This fitting is used in residential and commercial plumbing systems, industrial fluid lines, and pneumatic circuits where a tee junction is needed in 1/4 inch FNPTF pipe runs. Its brass construction resists corrosion in water, air, oil, and many common fluid media. The compact overall length of 1-9/16 inches allows installation in tight panel spaces and equipment enclosures. Applications include compressed air distribution, hydraulic control lines, fuel systems, and general-purpose industrial piping wherever FNPTF-threaded connections are specified.

Key Features

• 1/4 inch FNPTF female thread on all three ports for standard pipe compatibility
• 1,200 psi maximum working pressure rating for high-pressure service
• Rated from -65 degrees F to 250 degrees F for broad temperature range coverage
• Brass construction provides corrosion resistance in water, air, oil, and fluid systems
• Compact 1-9/16 inch overall length suits confined installation spaces
• Meets ASA, ASME, and SAE 130438 standards for verified dimensional and pressure compliance

Compatibility

Designed as an OEM-style replacement and standard-fit component for industrial and commercial pipe systems using 1/4 inch FNPTF threaded connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable ASME and local piping codes. Depressurize and isolate the pipe system completely before removing any existing fittings or threading in the new tee. Apply thread sealant or PTFE tape appropriate for the fluid media being conveyed. Do not exceed the rated working pressure or temperature limits for the installed application.
