The ASC ENGINEERED SOLUTIONS EXD.NMT is a malleable iron galvanized pipe reducing tee rated at 150 lb, sized 3/4 x 3/4 x 1/2 inches with female national pipe taper (FNPT) threads on all three outlets. It is designed to split or branch a threaded pipe run while simultaneously reducing the branch outlet from 3/4 to 1/2 inch. The galvanized finish provides corrosion resistance for use in wet or exposed environments. This fitting is manufactured domestically and suits plumbing, gas distribution, and mechanical piping applications where a reliable threaded branch connection with a size reduction is required. Licensed plumbers and pipefitters are the primary installers of this type of fitting.
This reducing tee is used in residential and light commercial threaded pipe systems, including water supply, gas piping, and general mechanical distribution lines. It is well-suited for installations where a main 3/4-inch line must continue straight while a reduced 1/2-inch branch is taken off. The 150 lb pressure class makes it appropriate for standard-service applications in these system types.
Designed as an OEM-style replacement or new-installation fitting compatible with standard 3/4-inch and 1/2-inch NPT threaded pipe systems in plumbing, gas, and mechanical piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes, including IPC and IFGC requirements where applicable. Shut off and depressurize the pipe system completely before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape to all male threads before assembly. Do not overtighten; use a pipe wrench with appropriate leverage for the fitting size and always inspect threads for damage before assembly.
