Asc Engineered Solutions 1B.NMC Pipe Coupling 1-1/4 in Fnpt

Product Description

The ASC Engineered Solutions 1B.NMC is a straight pipe coupling designed for joining threaded pipe sections in pressurized piping systems. It features female NPT (FNPT) threads on both ends and is pressure-rated to 150 lb, making it suitable for standard gas, water, and steam distribution applications. Constructed from malleable iron with a galvanized finish, it resists corrosion in demanding service environments. This fitting is a domestically manufactured product and is installed by licensed plumbers, pipefitters, and HVAC technicians working on threaded iron pipe systems.

The 1B.NMC is suited for residential and light commercial piping installations where a 1-1/4 inch nominal threaded straight connection is required. Typical applications include natural gas distribution, potable water supply, steam lines, and general industrial pipe runs. The FNPT end style accepts standard NPT-threaded pipe on both sides, allowing a direct inline coupling without offset or transition.

Key Features

• 1-1/4 inch nominal size with FNPT threading on both ends for inline pipe joining
• 150 lb pressure rating suitable for gas, water, and steam service
• Malleable iron construction provides strength and impact resistance
• Galvanized finish for added corrosion protection in wet or outdoor environments
• Domestically manufactured to standard pipe fitting dimensions

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch nominal NPT threaded iron pipe systems rated at 150 lb class service pressure.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to the male NPT threads before assembly. Do not over-torque malleable iron fittings, as the material can crack under excessive force.
