Anvil 1BX1.NMT Malleable Iron Galvanized Reducing Tee

Product Description

The ANVIL 1BX1.NMT is a malleable iron galvanized reducing tee fitting designed for threaded pipe systems in plumbing, mechanical, and light industrial applications. It features a tee shape with a reduced outlet, sized at 1-1/4 x 1-1/4 x 1 inches, allowing a branch connection at a smaller diameter than the run. Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 fitting handles demanding service conditions. The galvanized finish provides corrosion resistance in exposed or mildly corrosive environments. Lead-free construction meets requirements for potable water and fuel gas piping installations.

This reducing tee is suited for residential and commercial piping systems where a branch line must transition to a 1-inch connection off a 1-1/4-inch main run. Typical applications include natural gas distribution, compressed air headers, water supply lines, and steam distribution at low-pressure ratings. Plumbers, pipefitters, and mechanical contractors install this fitting as part of threaded black or galvanized iron pipe assemblies in both new construction and retrofit projects.

Compatibility

Designed as an OEM-style replacement and standard fitting for Class 150 threaded malleable iron pipe systems using 1-1/4-inch and 1-inch NPT pipe.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter following applicable codes including the International Plumbing Code and International Fuel Gas Code. Shut off and depressurize the pipe system completely before cutting into or modifying any existing line. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly and tighten to hand-tight plus the appropriate number of turns for the pipe size. Do not overtighten malleable iron fittings, as the material can crack under excessive torque.
