Asc Engineered Solutions 1DX1.NML Reducing 90 Elbow 1.5x1 Fnpt

Product Description

The ASC ENGINEERED SOLUTIONS 1DX1.NML is a reducing 90-degree elbow fitting designed for threaded pipe systems in commercial and industrial plumbing, HVAC piping, and mechanical installations. It transitions from a 1-1/2 inch female NPT inlet to a 1 inch female NPT outlet while making a 90-degree directional change in a single fitting. Rated at 150 lb, this elbow is constructed from malleable iron with a hot-dip galvanized finish that provides corrosion resistance for both exposed and concealed applications. Licensed plumbers and pipefitters are the primary installers of this class of fitting.

This fitting is suited for residential and commercial mechanical rooms, boiler piping, water distribution, compressed air lines, and general industrial pipe runs where a reducing 90-degree turn is required. The galvanized finish makes it appropriate for wet or humid environments where bare iron fittings would be at higher risk of corrosion. Domestic manufacture supports project specifications that require US-made materials for government or prevailing-wage jobs.

Key Features

• Reduces from 1-1/2 inch to 1 inch FNPT in a single 90-degree elbow — eliminates the need for a separate reducer and elbow
• 150 lb pressure class malleable iron construction for durable threaded pipe service
• Galvanized finish provides corrosion resistance in wet and humid environments
• Female NPT threads on both ends for standard tapered pipe thread assembly
• Domestically manufactured — meets project specs requiring US-origin pipe fittings

Compatibility

Designed as an OEM-style replacement and standard fitting for 150 lb class malleable iron threaded pipe systems using 1-1/2 inch and 1 inch NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local mechanical codes. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to the male threads being joined — do not apply sealant to female threads. Do not over-torque the connection; follow standard hand-tight-plus-turns practice for the pipe size and material.
