Asc Engineered Solutions 1DXE.NML Reducing 90 Degree Elbow

Product Description

The ASC Engineered Solutions 1DXE.NML is a reducing 90-degree pipe elbow rated at 150 lb, manufactured from galvanized malleable iron for use in threaded piping systems. It transitions from a 1-1/2 inch female NPT inlet to a 3/4 inch female NPT outlet, allowing a right-angle direction change while simultaneously reducing pipe size in a single fitting. The galvanized finish provides corrosion resistance for use in moderate-exposure environments. Domestically manufactured, this fitting is suited for plumbing, HVAC hydronic piping, gas distribution, and general industrial pipe systems where a durable, code-compliant threaded connection is required.

This fitting is used in residential and light commercial piping applications that require both a 90-degree change in flow direction and a reduction in pipe diameter. Typical installation scenarios include hydronic heating supply and return lines, water distribution headers, compressed air systems, and low-pressure gas piping where malleable iron fittings are specified. Licensed plumbers and pipefitters install this type of fitting during new construction or retrofit work on threaded iron pipe systems.

Key Features

• Reduces from 1-1/2 inch to 3/4 inch FNPT in a single 90-degree fitting, eliminating the need for a separate reducer
• 150 lb pressure-rated malleable iron construction for reliable performance in standard service applications
• Galvanized finish for added corrosion resistance in exposed or moderate-moisture environments
• Female NPT threads on both ends for standard threaded pipe connection
• Domestically manufactured fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1-1/2 inch and 3/4 inch NPT threaded iron pipe systems rated for 150 lb service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements where used on gas systems. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to male threads before assembly, and tighten to hand-tight plus a standard number of turns using a pipe wrench. Do not overtighten malleable iron fittings, as cracking can occur.
