B K/mueller Inds(import) 520-603HN Black Equal Tee 1/2 in

Product Description

The B K/MUELLER INDS(IMPORT) 520-603HN is a 1/2-inch black malleable iron equal tee used in threaded pipe assemblies for gas distribution and general piping systems. This fitting connects three sections of pipe at equal diameters, allowing a branch line to split off a main run at a 90-degree angle. The black iron finish suits dry indoor gas piping where corrosion resistance requirements are standard for that service type. Licensed plumbers, pipefitters, and gas technicians install these fittings during new construction, system modification, or repair work on threaded iron pipe systems.

This equal tee is suited for residential and light commercial gas piping applications, including natural gas and propane distribution lines. The 1/2-inch threaded configuration fits standard schedule 40 iron pipe. It ships in a package quantity of 25 units, making it practical for contractors stocking material for multiple jobs or larger piping runs. Installation follows standard threaded pipe assembly practices with appropriate pipe thread sealant or tape approved for gas service.

Installation Notes

Installation should be performed by a licensed plumber or gas fitter in accordance with local codes and the International Fuel Gas Code (IFGC) where applicable. Shut off and purge the gas supply before disassembling or modifying any section of the piping system. Apply a pipe thread sealant or PTFE tape rated for gas service to all male threads before assembly. Do not over-tighten threaded connections; use proper pipe wrenches and follow standard trade practice for joint integrity.
