The MSI PRODUCTS INC A22202202024 is a 150lb galvanized malleable iron reducing tee designed to connect three sections of threaded pipe while transitioning to a smaller branch size. With a 1-1/4 x 1-1/4 x 1-1/2 inch configuration, this fitting allows branch line reductions without additional components. Rated for 150-300 PSI service, it is built in a heavy pattern design to meet the strength demands of commercial and industrial piping systems. A galvanized coating provides corrosion resistance for extended service life in harsh environments. Each fitting carries full lot traceability with material test reports available on request. Manufactured to ASME B16.3, ASTM A197, and ASME B1.20.1 standards in an ISO-certified facility.
This reducing tee is suited for residential and commercial threaded pipe installations where a branch line must transition to a smaller pipe diameter. Common applications include water distribution, HVAC hydronic systems, compressed air lines, and general plumbing branch connections. The 150lb pressure class makes it appropriate for standard-service threaded iron pipe assemblies. Licensed plumbers and pipefitters typically install this fitting as part of new construction or retrofit piping work.
Designed as an OEM-style replacement fitting for standard 150lb threaded malleable iron pipe systems conforming to ASME B16.3 and ASME B1.20.1 thread specifications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IPC requirements. Shut off and depressurize the pipe system completely before disassembly or fitting installation. Apply an appropriate pipe thread sealant or PTFE tape to all male threads before assembly. Do not over-torque the fitting, as malleable iron fittings can crack if excessive force is applied.
