Asc Engineered Solutions 1.NMSL Street Elbow 1 Inch Malleable Iron

Product Description

The ASC Engineered Solutions 1.NMSL is a 1-inch nominal malleable iron street elbow used to change pipe direction in threaded piping systems. It features a male NPT inlet on one end and a female NPT outlet on the other, allowing a direct connection without a separate coupling. The galvanized finish provides corrosion resistance for use in exposed or moderately harsh environments. Rated at 150 lb, this fitting is suitable for low-pressure gas, water, and steam service in both residential and light commercial applications. Licensed plumbers and pipefitters are the primary installers for this type of fitting.

This street elbow is used in threaded iron pipe systems where a directional change is needed in a compact space. The male-by-female thread configuration eliminates the need for an additional fitting at the connection point, saving time and reducing potential leak paths. Typical install scenarios include gas distribution piping, water supply lines, and HVAC hydronic systems. The domestic manufacturing designation indicates the fitting meets domestic production standards commonly required on public projects and prevailing wage jobs.

Key Features

• 1-inch nominal MNPT x FNPT thread configuration for direct inline directional change

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements for gas service. Shut off the supply line and depressurize the system before removing any existing fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten, as malleable iron fittings can crack under excessive torque.
