The MATCO-NORCA ibma04lf is a lead free yellow brass insert-by-male pipe thread (IXMPT) adapter sized at 3/4 inch. This fitting connects insert-style tubing to a male NPT threaded port, making it a practical transition piece in water supply and distribution piping assemblies. Yellow brass construction provides reliable corrosion resistance in potable water applications. The lead free designation meets current federal and state safe drinking water standards for use in systems that carry water intended for human consumption. Licensed plumbers and pipefitters are the primary installers of this adapter in both new construction and retrofit work.
This adapter is suited for residential and light commercial plumbing systems where a transition between insert tubing and a threaded male connection is needed. Typical applications include water supply lines, fixture connections, and distribution manifold hookups. The 3/4 inch size fits common main distribution and branch line sizing found throughout residential and commercial construction.
Designed as an OEM-style replacement and standard fitting for residential and light commercial plumbing systems requiring a 3/4 inch insert-by-male pipe thread adapter connection.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure completely before removing or installing any fitting. Apply thread sealant tape or compound to the male NPT threads before assembly to ensure a leak-free connection. Do not overtighten, as brass fittings can crack under excessive torque.
