Asc Engineered Solutions 1DX1B.NML Reducing 90 Deg Elbow

Product Description

The ASC Engineered Solutions 1DX1B.NML is a reducing 90-degree pipe elbow rated for 150 lb service, manufactured from galvanized malleable iron. It connects a 1-1/2 inch female NPT inlet to a 1-1/4 inch female NPT outlet, allowing a direction change and pipe size reduction in a single fitting. The galvanized finish provides corrosion resistance for use in wet or mildly corrosive environments. This is a domestically produced fitting suited for plumbing, HVAC piping, gas distribution, and general industrial pipe systems where a right-angle transition between two pipe sizes is required.

This fitting is used in residential and light commercial piping systems where a 90-degree change of direction is needed alongside a reduction from 1-1/2 inch to 1-1/4 inch pipe. Typical applications include supply and return water lines, natural gas and propane distribution piping, compressed air systems, and steam service within the 150 lb pressure class rating. Licensed plumbers, pipefitters, and HVAC mechanics commonly install this type of fitting during new construction and retrofit projects.

Key Features

• Combines a 90-degree directional change and a pipe size reduction in one fitting
• 1-1/2 inch x 1-1/4 inch FNPT connections for standard threaded pipe
• 150 lb pressure class rating suitable for water, gas, and steam service
• Galvanized malleable iron construction for corrosion resistance and impact toughness
• Domestically produced to meet standard pipe fitting dimensional requirements

Compatibility

Designed as an OEM-style threaded fitting compatible with standard 1-1/2 inch and 1-1/4 inch NPT threaded pipe in 150 lb malleable iron piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC codes for the service type. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before making up the joint. Do not over-tighten, as malleable iron fittings can crack if excessive force is applied.
