Eaton 3750X12 Brass Street Tee 3/4 Inch Mnptf X Fnptf

Product Description

The EATON 3750X12 is a brass street tee fitting designed for industrial pipe assemblies requiring a compact tee connection without a separate nipple. The male NPT thread on one end and female NPT threads on the remaining ports allow this fitting to thread directly into a female-threaded outlet, saving space in tight manifold or distribution configurations. Rated to 1,200 psi maximum working pressure and suitable for temperatures ranging from -65 degrees F to 250 degrees F, it handles demanding fluid and gas service conditions. The brass construction resists corrosion in water, air, and many hydraulic fluid applications. Plumbers, pipefitters, and industrial maintenance technicians install this fitting in both commercial and industrial settings.

The 3750X12 is suited for residential and commercial plumbing, compressed air lines, hydraulic systems, and fluid distribution networks where a tee branch is required at an existing threaded port. The 3/4-inch thread size fits standard 3/4-inch NPT pipe runs. Its street-tee configuration is commonly used when an inline branch must be added directly at a valve, manifold, or pump port without additional pipe extensions.

Key Features

• MNPTF x FNPTF connection type ensures compatibility with standard NPT pipe threads
• Meets ASA, ASME, and SAE 130424 standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4-inch NPT threaded pipe systems in industrial, commercial, and plumbing applications conforming to ASA, ASME, and SAE 130424 standards.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Depressurize and isolate the line before removing any existing fittings or installing this tee. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten; use a proper pipe wrench and follow standard NPT thread engagement practice to avoid cracking the fitting body.
