B K Mueller 510-334HN Galvanized Reducing Tee 1/2x1/2x3/4 in

Product Description

The B K Mueller Industries 510-334HN is a galvanized reducing tee fitting used to join and redirect threaded pipe runs where a size transition is required. This tee connects a 1/2-inch run with a 3/4-inch branch outlet, allowing flow to be split or redirected across different pipe diameters in a single fitting. It is manufactured from galvanized steel, providing corrosion resistance suitable for water distribution, gas, and general-purpose piping systems. Plumbers and pipefitters install this type of fitting in both new construction and retrofit work where threaded black or galvanized iron pipe is specified.

This reducing tee is suited for residential and light commercial plumbing and gas piping applications. It is commonly used in water supply lines, compressed air systems, and natural gas distribution where a branch connection of a different diameter is needed. The fitting ships in a package quantity of 25 units, making it practical for contractors stocking common fittings on service vehicles or job sites.

Installation Notes

Installation of threaded galvanized fittings is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the supply line fully before cutting into or modifying any pipe run. Apply thread sealant tape or paste rated for the intended service — water, gas, or air — before making up the connection. Installations involving gas piping must comply with applicable IFGC or local gas code requirements and should be leak-tested before restoring service.
