The MATCO-NORCA ibma05lf is a 1-inch lead free yellow brass adapter fitting designed to connect IPS (Iron Pipe Size) to MPT (Male Pipe Thread) in potable water and plumbing distribution systems. Constructed from lead free yellow brass, this fitting meets the requirements for use in drinking water applications where lead free compliance is mandated. Plumbers and pipefitters install this adapter when transitioning between IPS-joined pipe and male-threaded connections in residential and light commercial systems.
This adapter is suited for use in water supply lines, pressure distribution systems, and general plumbing installations where a reliable IPS to MPT transition is needed. The 1-inch size makes it appropriate for main supply branches and distribution manifold connections. It is installed by licensed plumbers working on potable water systems in both new construction and retrofit applications.
Designed as an OEM-style replacement or standard fitting for 1-inch IPS to MPT transitions in residential and light commercial potable water plumbing systems.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and relieve system pressure before beginning any fitting installation. Apply thread sealant tape or paste to male threads per standard practice. Do not overtighten threaded brass fittings, as this can cause cracking or thread damage.
