Msi Products Inc A20202080812 Reducing Tee 150lb Black

Product Description

The MSI PRODUCTS INC A20202080812 is a 150-pound class black malleable iron reducing tee designed to connect three sections of threaded pipe while transitioning to a smaller branch size. The fitting measures 1/2 inch on the run inlets and 3/4 inch on the branch outlet, making it suited for branch line reductions within threaded pipe systems. Constructed in a heavy pattern design, it conforms to ASME B16.3 dimensional standards, ASTM A197 material specifications, and ASME B1.20.1 threading standards. Rated for service between 150 and 300 psi, this fitting is installed by licensed plumbers and pipefitters in gas, steam, and water distribution systems. Full lot traceability and material test reports are available upon request to support quality and compliance documentation.

This reducing tee is used in residential and light commercial piping applications where a branch line must transition to a different pipe diameter without adding extra adapters or couplings. Typical install scenarios include gas distribution headers, steam supply lines, and industrial water systems where threaded black iron pipe is the standard. The fitting ships individually and is suited for single-point replacements or new construction rough-in work. Manufactured in an ISO-certified facility, each fitting is tested for dimensional consistency and performance before leaving the production floor.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code or International Plumbing Code as required. Shut off and depressurize the pipe system fully before removing any existing fitting or making new connections. Apply a listed pipe thread sealant or PTFE tape to all male threads before assembly, and tighten to a snug fit using a pipe wrench - do not over-torque malleable iron fittings. Inspect all joints for leaks after system pressure is restored.
