Asc Engineered Solutions 1XD.NML 90 Degree Reducing Pipe Elbow

Product Description

The ASC ENGINEERED SOLUTIONS 1XD.NML is a reducing 90-degree pipe elbow designed for threaded piping systems in commercial and industrial plumbing, HVAC, and gas distribution applications. This fitting transitions from a 1-inch female NPT inlet to a 1/2-inch female NPT outlet while making a 90-degree directional change in a single component. Constructed from malleable iron with a galvanized finish, it carries a 150 lb pressure rating suitable for low-pressure steam, water, gas, and air service. Licensed plumbers and pipefitters install this type of fitting as part of threaded pipe assemblies where both a size reduction and a directional change are required at the same point in the run.

This elbow is suited for residential and light commercial piping installations where standard 150 lb malleable iron fittings are specified. Typical applications include water supply lines, compressed air distribution, natural gas branch lines, and hydronic heating systems. The galvanized coating provides corrosion resistance in exposed or moderately humid environments. Domestic manufacture supports project specifications requiring USA-made components.

Key Features

• Reduces from 1-inch to 1/2-inch in a single 90-degree fitting, eliminating the need for a separate reducer
• Female NPT threads on both ends for standard threaded pipe connections
• 150 lb pressure-class malleable iron construction for low-pressure steam, water, gas, and air service
• Galvanized finish for corrosion resistance in exposed piping environments
• Domestically manufactured to support USA-sourcing project requirements

Compatibility

Designed as a standard 150 lb malleable iron FNPT fitting compatible with 1-inch and 1/2-inch NPT-threaded pipe in residential and commercial threaded piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC or IFGC requirements for the specific service type. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to the male threads before assembly and tighten to hand-tight plus the number of turns specified by the sealant manufacturer. Do not over-torque malleable iron fittings, as the material is strong but not ductile under extreme stress.
