B K Mueller 520-605HN 1 Inch Black Equal Tee 5 Pack

Product Description

The B K Mueller Industries 520-605HN is a 1-inch black equal tee fitting used in threaded pipe systems for gas distribution, air, and other compatible services. This malleable iron fitting connects three sections of pipe at equal branch angles, making it a standard component in residential and light commercial gas piping runs. Licensed plumbers and pipefitters install this fitting during new construction and retrofit work. It ships in a package of 5, making it practical for multi-connection jobs or service vans that need backstock on hand.

This fitting is appropriate for 1-inch threaded black iron pipe systems commonly found in natural gas and propane distribution lines inside residential homes and light commercial buildings. It is also used in compressed air distribution and certain industrial fluid systems where malleable iron threaded fittings are specified. The equal-branch design makes it a go-to fitting when a full-flow tee off a main line is needed without reducing the branch size.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC requirements for gas piping. Shut off the gas supply and verify zero pressure at the line before disassembling or connecting any fittings. Apply an approved pipe thread sealant or PTFE tape rated for gas service to all male threads before making up the joint. Pressure-test the completed assembly before returning the system to service.
