Asc D.NMSL 1/2 Inch Street Elbow 150 Lb Malleable Iron

Product Description

The ASC Engineered Solutions D.NMSL is a 1/2 inch nominal street elbow designed for threaded pipe assemblies in plumbing, gas distribution, and mechanical piping systems. Constructed from malleable iron with a galvanized finish, this fitting provides a directional change in a run of pipe using a male NPT inlet and a female NPT outlet on a single compact fitting. The 150 lb pressure rating makes it suitable for a wide range of low- and medium-pressure service applications. Licensed plumbers and pipefitters use this fitting when a standard elbow and a separate nipple would otherwise be required, saving space and reducing joint count in tight installations.

This street elbow is used in residential and light commercial piping systems where a 90-degree directional change is needed directly off a male-threaded connection. Typical applications include gas lines, water distribution, compressed air headers, and steam systems rated within the 150 lb class. The galvanized coating provides corrosion resistance for both indoor and exposed mechanical room environments. It is a domestic-made fitting, which satisfies Buy American requirements on qualifying public projects.

Key Features

• 1/2 inch nominal size with MNPT inlet and FNPT outlet for direct-connection directional changes
• 150 lb pressure class malleable iron construction for reliable service in gas, water, and air systems
• Galvanized finish provides corrosion resistance in damp or exposed mechanical environments
• Compact street configuration eliminates the need for a separate close nipple at direction changes
• Domestic manufacture supports Buy American compliance requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1/2 inch NPT threaded pipe systems rated at 150 lb class.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC requirements depending on the service fluid. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten malleable iron fittings, as the material can crack under excessive torque. Depressurize and isolate the line completely before removing or installing any threaded fittings.
