B K Mueller 520-743HN Black Reducing Tee 3/4x1/2 in

Product Description

The B K Mueller Industries 520-743HN is a black reducing tee fitting designed for threaded pipe assemblies in gas distribution and general piping systems. This fitting transitions from a 3/4-inch run to a 1/2-inch branch, allowing a single fitting to serve both the through-line and the branch takeoff. Sold in a package of 10 units, it is a standard choice for plumbers and gas fitters working on residential and light commercial pipe runs where reducing connections are needed at a junction point.

This reducing tee is suited for black iron pipe systems commonly found in natural gas and propane distribution lines, as well as general-purpose low-pressure piping applications. The 3/4-inch by 1/2-inch configuration is one of the most common reducing combinations encountered in residential gas supply rough-in work, making this 10-pack practical for service companies and contractors who install or repair multiple connections per job.

Key Features

• Reducing tee configuration: 3/4-inch run by 1/2-inch branch for in-line size transitions
• Black finish standard for gas piping identification and corrosion resistance in dry installations
• Threaded ends for connection to standard NPT black iron pipe
• Sold as a 10-unit pack, reducing per-unit cost for multi-connection jobs
• Package weight of 4.51 pounds for the full 10-pack

Compatibility

Designed as an OEM-style replacement and standard fitting for threaded black iron pipe systems using NPT connections in residential and light commercial gas and general piping applications.

Installation Notes

Black reducing tees of this type are installed by licensed plumbers or gas fitters in jurisdictions that regulate gas piping work. Shut off the gas supply and verify line pressure is relieved before disassembling any existing fittings. Apply approved thread sealant or PTFE tape rated for gas service to all male threads before assembly. All gas piping installations must comply with local codes and the International Fuel Gas Code (IFGC) where adopted.
