Asc Engineered Solutions 1DXD.BML Reducing 90 Deg Elbow

Product Description

The ASC Engineered Solutions 1DXD.BML is a reducing 90-degree pipe elbow rated at 150 lb, manufactured from black malleable iron. It connects a 1-1/2 inch female NPT inlet to a 1/2 inch female NPT outlet, allowing a directional change and size reduction in a single fitting. Malleable iron construction provides the ductility and strength required for threaded piping systems carrying gas, steam, air, or water. This fitting is domestically manufactured and suited for use in both commercial and residential mechanical systems.

This elbow is a standard choice for plumbers, pipefitters, and mechanical contractors working on gas distribution, steam, compressed air, or hydronic piping systems. The 1-1/2 inch to 1/2 inch reduction makes it useful in branch-off configurations where a main line must feed a smaller-diameter service line, eliminating the need for a separate reducer and elbow. It is appropriate for both new construction and retrofit piping work wherever a combined direction change and pipe reduction is required.

Key Features

• Reducing configuration changes direction and pipe size in one fitting, from 1-1/2 inches to 1/2 inch
• 90-degree bend for right-angle pipe routing
• Female NPT threads on both ends for standard threaded pipe connections
• 150 lb pressure class rating suitable for steam, gas, air, and water service
• Black malleable iron construction provides ductility and resistance to cracking under stress
• Domestically manufactured to standard pipe fitting dimensions

Compatibility

Designed as an OEM-style replacement or standard-service fitting for threaded malleable iron piping systems using 1-1/2 inch and 1/2 inch NPT pipe.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters. Always depressurize and isolate the piping system before making or breaking any threaded connection. Apply an approved thread sealant or PTFE tape to male threads before assembly; do not over-tighten, as malleable iron fittings can crack under excessive torque. Work must comply with applicable local codes, including the International Fuel Gas Code for gas piping and the International Plumbing Code for water and steam systems.
