The ANDERSON METALS CORP 738119-1208 is a rough brass reducing coupling designed to connect pipes of two different diameters in water supply and distribution systems. It transitions from a 3/4-inch female connection to a 1/2-inch female connection, making it a standard solution for downsizing runs in residential and light commercial plumbing. The fitting is lead free compliant and meets the requirements of Public Law 111-380, which mandates lead-free materials in potable water applications. Licensed plumbers rely on this type of fitting for reliable, code-compliant joints in copper and brass piping systems.
This reducing coupling is suited for residential and light commercial potable water supply lines where a size transition is required between trunk lines and branch lines. It is commonly installed at branch takeoffs, near fixtures, or within distribution manifolds where 3/4-inch mains feed 1/2-inch service lines. The fitting ships in bulk packaging with a package quantity of five units, making it practical for service vehicles or job-site stock.
Designed as an OEM-style brass reducing coupling for residential and light commercial potable water supply piping systems requiring a 3/4-inch to 1/2-inch female threaded transition.
Installation of this fitting is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off water supply and relieve system pressure before beginning work. Apply thread sealant or PTFE tape to male threads before assembly and tighten to hand-tight plus wrench-snug — do not over-torque brass fittings, as the material is susceptible to cracking under excessive force. Inspect the joint for leaks after restoring pressure.
