Asc Engineered Solutions 1B.NMSL Street Elbow 1-1/4 in

Product Description

The ASC Engineered Solutions 1B.NMSL is a 1-1/4 inch nominal malleable iron street elbow rated for 150 lb service. It features a male NPT (MNPT) inlet on one end and a female NPT (FNPT) outlet on the other, allowing a 90-degree change in pipe direction without the need for an additional fitting. The galvanized finish provides corrosion resistance for use in exposed or moderately harsh environments. Plumbers and pipefitters install this fitting in threaded pipe assemblies for gas, water, and general-purpose piping systems where a compact directional change is required.

This street elbow is suited for residential and light commercial plumbing, gas distribution, and mechanical piping applications. Because the MNPT end threads directly into a tee, coupling, or valve without a separate nipple, it saves space in tight runs. Domestically produced, it is commonly specified on jobs where domestic-origin fittings are required by contract or code. Licensed plumbers and pipefitters handle installation as part of larger threaded pipe systems.

Key Features

• 1-1/4 inch nominal size suits a wide range of standard threaded pipe systems
• MNPT x FNPT end configuration eliminates the need for a separate close nipple
• 150 lb pressure rating for general-purpose threaded piping service
• Malleable iron construction provides strength and ductility in threaded connections
• Galvanized finish resists corrosion in exposed or damp installations
• Domestic manufacture meets project specifications requiring US-origin fittings

Compatibility

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

Installation Notes

Installation is performed by a licensed plumber or pipefitter in accordance with applicable code requirements such as the IPC or IFGC depending on the service. Shut off and depressurize the pipe system fully before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape to the male threads before assembly and tighten to a snug, leak-free fit using pipe wrenches. Do not overtighten, as malleable iron threads can crack under excessive torque.
