B K/mueller Inds(import) 520-601HN Black Equal Tee

Product Description

The B K/MUELLER INDS(IMPORT) 520-601HN is a 0.25-inch black equal tee fitting used in gas distribution and low-pressure piping systems. It provides a three-way branch connection where all three openings share the same pipe size, making it a standard choice for splitting or combining flow in a single plane. Licensed plumbers and pipefitters install this fitting in residential and light commercial applications where black iron pipe is the specified material. Each package contains 10 pieces, and the unit weight is 1.45 pounds per package.

This fitting is suited for 0.25-inch black iron pipe runs in natural gas, propane, and similar low-pressure distribution systems. It is commonly installed in residential gas supply lines, commercial kitchen rough-in work, and mechanical room piping where branch takeoffs are required. The equal-tee configuration means no reducer bushings or adapters are needed when all three legs share the same nominal pipe size.

Key Features

• Equal tee configuration — all three ports at 0.25-inch nominal size, no reducers required
• Black iron construction compatible with standard threaded black pipe fittings
• Sold in a package of 10 units for efficient job-site stocking
• Suitable for low-pressure gas and fluid distribution piping

Compatibility

Designed as an OEM-style replacement fitting for 0.25-inch nominal black iron threaded pipe systems in residential and light commercial gas and fluid piping applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) where gas service is involved. Shut off and verify zero pressure in the gas or fluid line before disassembling any section of pipe. Apply an appropriate pipe thread sealant or PTFE tape rated for gas service to all male threads before assembly. Do not overtighten threaded connections, as black iron fittings can crack under excessive force.
