Asc Engineered Solutions 1B.NMT Pipe Tee 1-1/4 in Fnpt 150 Lb

Product Description

The ASC Engineered Solutions 1B.NMT is a 1-1/4 inch malleable iron pipe tee designed for threaded piping systems operating at up to 150 lb pressure class. All three ports are female NPT (FNPT), allowing direct connection to standard NPT-threaded pipe and fittings. The galvanized finish provides corrosion resistance in exposed or moderately corrosive environments. This tee is domestically produced and suited for use by licensed plumbers, pipefitters, and mechanical contractors working on gas, water, and steam distribution systems.

This fitting is commonly used in residential and light commercial plumbing, gas distribution, and heating piping systems where a branch connection is needed off a main run. The FNPT threading on all three ports makes it compatible with standard NPT pipe in 1-1/4 inch nominal size. The galvanized coating makes it appropriate for installations where bare iron would be exposed to moisture or corrosive atmospheric conditions.

Key Features

• 1-1/4 inch nominal size with FNPT connections on all three ports
• 150 lb pressure class rating suitable for gas, water, and steam service
• Malleable iron construction offers impact resistance and ductility compared to cast iron
• Galvanized finish provides corrosion protection in exposed installations
• Domestically manufactured fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1-1/4 inch NPT threaded pipe and fittings in 150 lb class piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly. Tighten fittings using a pipe wrench to achieve proper thread engagement without over-torquing, which can crack the fitting. Always depressurize and isolate the system before removing or replacing any threaded fitting.
