Asc Engineered Solutions 1B.NML 90 Degree Elbow 1-1/4 in

Product Description

The ASC Engineered Solutions 1B.NML is a 90-degree pipe elbow designed for directional changes in threaded pipe systems. Built from malleable iron with a galvanized finish, it provides corrosion resistance suitable for a range of plumbing, gas distribution, and mechanical piping applications. The fitting accepts 1-1/4 inch female National Pipe Taper (FNPT) connections on both ends and is rated at 150 lb, making it appropriate for standard-pressure service lines. Licensed plumbers and pipefitters are the primary installers of this fitting in both new construction and retrofit work.

This elbow is used in residential and light commercial piping systems where a 90-degree directional change is required. Typical applications include natural gas distribution lines, compressed air systems, water supply piping, and general mechanical systems that rely on threaded iron pipe. The galvanized coating adds a layer of protection against moisture and mild corrosive environments. Its domestic manufacture supports job specifications that require U.S.-made components.

Key Features

• 90-degree elbow for directional changes in threaded iron pipe systems
• 1-1/4 inch FNPT connections on both ends for standard threaded pipe assembly
• 150 lb pressure rating for standard-service piping applications
• Malleable iron construction for strength and impact resistance
• Galvanized finish for corrosion protection in moisture-exposed environments
• Domestically manufactured to support U.S.-origin project requirements

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code (IPC), or the International Fuel Gas Code (IFGC) where gas service applies. Shut off the gas or water supply and depressurize the line before disassembly or fitting installation. Apply an appropriate thread sealant or PTFE tape to the male pipe threads before assembly — do not apply sealant to female threads. Avoid over-torquing the connection, as malleable iron fittings can crack under excessive force.
