Asc Engineered Solutions 1DX1B.BML 90 Deg Reducing Elbow

Product Description

The ASC Engineered Solutions 1DX1B.BML is a reducing 90-degree pipe elbow designed for threaded pipe assemblies in plumbing, mechanical, and gas distribution systems. Manufactured from black malleable iron, this fitting is rated at 150 lb and transitions from a 1-1/2 inch female connection to a 1-1/4 inch female connection using FNPT (female national pipe taper) threads. Its black finish is standard for gas service applications. Licensed plumbers and pipefitters install this type of fitting when a run must change direction and simultaneously step down in pipe diameter within a single compact fitting.

This elbow is suited for residential and light commercial applications including natural gas supply lines, steam and hot water heating systems, compressed air distribution, and general-purpose pipe runs. The domestic manufacture designation indicates production within the United States, which is often a requirement on public works and government projects. The 1-1/2 inch to 1-1/4 inch reducing configuration eliminates the need for a separate reducing coupling in a 90-degree change-of-direction scenario.

Key Features

• Reducing configuration transitions 1-1/2 inch to 1-1/4 inch in a single fitting
• 90-degree turn simplifies directional changes without additional fittings
• 150 lb pressure-rated malleable iron construction
• FNPT threads on both ends for standard tapered pipe thread compatibility
• Black finish suitable for gas service pipe systems
• Domestic manufacture for projects requiring USA-produced components

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 150 lb malleable iron threaded pipe systems using 1-1/2 inch and 1-1/4 inch NPT pipe.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code (IPC), or the International Fuel Gas Code (IFGC) for gas service applications. Shut off the gas or water supply and verify zero pressure at the line before disassembling any existing fittings. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-tighten; follow fitting manufacturer guidance for thread engagement depth appropriate to the pipe size.
