The HAILIANG HL15-460-0305 is a copper reducing tee fitting sized at 1-1/2 inches by 1-1/2 inches by 3/4 inches, configured with a copper-to-copper-to-copper (C x C x C) end connection on all three ports. This fitting is used to branch a 3/4-inch outlet off a 1-1/2-inch run in a copper piping system. The OD dimensions measure 1-5/8 inches by 1-5/8 inches by 7/8 inches. Plumbers install this fitting during new construction or retrofit work where a smaller branch line must be tapped into a full-size run without adding an inline reducer separately. The all-copper construction ensures compatibility with standard sweat-solder joining methods used throughout residential and commercial plumbing systems.
This reducing tee is suited for domestic water distribution, hydronic heating piping, and general plumbing rough-in applications where a 3/4-inch branch is required off a 1-1/2-inch main. It is appropriate for both residential and light commercial installations and is sized per common copper tube standards. Licensed plumbers and pipefitters working on supply piping, recirculation loops, or branch distribution headers will encounter this fitting type regularly in both new-build and remodel scenarios.
Designed as an OEM-style copper reducing tee for use with 1-1/2-inch and 3/4-inch copper tubing systems joined by sweat-solder connections per standard plumbing practice.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and drain the water supply completely before cutting into existing piping. Clean and flux all mating surfaces thoroughly before soldering to ensure a leak-free joint. Allow the fitting to cool fully before restoring system pressure and inspecting all joints for leaks.
