Macomb Group Approved 250BLGPOL3 Grooved Branch Outlet

Product Description

The MACOMB GROUP APPROVED 250BLGPOL3 is a grooved-end branch outlet fitting, commonly called a pipe olet, designed for steel piping systems where a branch connection must be made to a larger run pipe. This fitting connects a 2.5-inch branch line to a 6-inch run pipe using grooved-end connections on both ends. Manufactured from welded steel with a black finish, it is built for commercial and industrial piping applications. Licensed trades including pipefitters and fire protection contractors typically specify this type of fitting for wet-pipe and dry-pipe fire suppression layouts as well as general mechanical piping systems.

This fitting is suited for commercial and industrial installations where grooved piping systems are the standard joining method. Typical applications include fire protection sprinkler mains, HVAC hydronic distribution headers, and process piping. The grooved-end design allows for faster assembly compared to threaded or flanged alternatives, making it a common choice on larger commercial jobsites. Its black steel construction is appropriate for above-ground interior piping in both new construction and retrofit work.

Key Features

• Branch size of 2.5 inches connects to a 6-inch run pipe
• Grooved-end connection type for use with standard groove couplings
• Welded steel construction provides strength for pressurized piping systems
• Black finish standard for interior mechanical and fire protection piping
• UL Listed and FM Approved for use in fire protection system applications

Compatibility

Designed as an OEM-style grooved branch outlet for use in steel grooved piping systems accepting a 2.5-inch branch on a 6-inch run pipe, compatible with standard grooved coupling systems.

Installation Notes

Installation should be performed by a licensed pipefitter or fire protection contractor in accordance with applicable mechanical and fire protection codes, including NFPA 13 for sprinkler systems where applicable. Depressurize and isolate the piping system completely before cutting or modifying any run pipe for branch outlet installation. Ensure the grooved ends are clean and free of burrs before seating couplings. Do not over-drive coupling bolts beyond the manufacturer torque range specified on the coupling packaging.
