Cerrobrass 127X-B Brass Street Tee 1/4 in Mnpt X Fnpt

Product Description

The CERROBRASS 127X-B is a brass street tee fitting designed for industrial pipe systems requiring a compact, in-line branch connection. It features a 1/4-inch male NPT (MNPT) run end and a 1/4-inch female NPT (FNPT) branch, allowing a tee to be threaded directly into an existing fitting without a nipple. Rated to 1,200 psi maximum working pressure, this fitting is suited for high-demand compressed air, gas, water, and hydraulic lines. Plumbers, pipefitters, and HVAC technicians install this type of fitting when a standard tee and nipple combination is not practical.

The 127X-B street tee is commonly used in residential, commercial, and light industrial piping applications where space is limited and a direct threaded branch connection is needed. Typical installations include compressed air distribution lines, water supply systems, fuel gas service piping, and refrigeration or HVAC equipment connections. The MNPT x FNPT configuration makes it adaptable to a wide range of standard pipe assemblies using 1/4-inch NPT threaded components.

Key Features

• 1,200 psi maximum working pressure rating for demanding service conditions
• Brass construction provides corrosion resistance and durability in fluid and gas systems
• Street tee design eliminates the need for an additional nipple at the run connection
• 1/4-inch MNPT x FNPT thread configuration for standard NPT pipe compatibility
• Compact dimensions suit installations where clearance is restricted

Compatibility

Designed as a direct-threaded replacement or new-installation fitting for 1/4-inch NPT piping systems in plumbing, HVAC, compressed air, and industrial fluid service applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable code requirements such as the IPC or IFGC depending on the service fluid. Shut off and depressurize the system completely before threading or unthreading any fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten threaded brass fittings, as brass is susceptible to thread damage under excessive torque.
