B K/mueller Inds(import) 520-604HN Black Equal Tee

Product Description

The B K/MUELLER INDS(IMPORT) 520-604HN is a 3/4 inch black malleable iron equal tee designed for use in threaded pipe assemblies. This fitting provides a three-way branch connection with equal-sized openings on all ports, making it a standard choice for distributing or combining flow in low-pressure piping systems. Plumbers and pipefitters install this type of fitting in gas distribution, compressed air, and water supply lines where a black iron fitting is required. The equal tee configuration simplifies layout planning in branch-line scenarios.

This fitting is commonly used in residential and light commercial applications involving black iron pipe systems. Typical installations include natural gas supply lines, propane distribution runs, and industrial compressed air networks. The 3/4 inch size is a frequently specified diameter in branch configurations where flow must be divided or redirected at a tee junction. Licensed plumbers and pipefitters handle this type of fitting during new construction and retrofit work.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as appropriate. Shut off and depressurize the line completely before disassembling or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
