The ASC Engineered Solutions 8700120853 is a 3/8-inch malleable iron galvanized tee fitting designed for threaded pipe assemblies in residential and commercial plumbing, HVAC piping, and general mechanical systems. The flat banded body meets Federal Specification WW-P-521F, ANSI B-16.3 for dimensions, and ANSI B-2.1 for pipe threads, ensuring consistent thread engagement and pressure-rated performance. The hot-dip galvanized finish provides corrosion resistance suitable for exposed or damp installations. At 0.254 pounds, this is a compact, standard-duty fitting installed by licensed plumbers and pipefitters working on threaded iron pipe runs.
This tee fitting is used wherever a branch takeoff is needed on a 3/8-inch threaded iron pipe run. Typical applications include hydronic heating distribution lines, compressed air systems, gas piping where local codes permit malleable iron fittings, and general water supply piping. The galvanized finish makes it a practical choice in utility spaces, mechanical rooms, and other environments where bare iron would be exposed to moisture.
Designed as an OEM-style replacement or standard fitting for 3/8-inch threaded malleable iron pipe systems in plumbing and mechanical applications.
Installation is performed by a licensed plumber or pipefitter using a pipe wrench and appropriate pipe thread sealant or PTFE tape rated for the service fluid. Shut off and depressurize the pipe system fully before removing any existing fittings or making new connections. Thread engagement must be consistent with ANSI B-2.1 tapered thread standards. Verify local code acceptance of galvanized malleable iron fittings for the intended service, particularly on gas piping.
