Asc 1XE.BML Reducing 90 Deg Elbow 1x3/4 in Fnpt 150lb

Product Description

The ASC Engineered Solutions 1XE.BML is a reducing 90-degree pipe elbow designed for threaded pipe systems in residential and commercial plumbing, gas distribution, and mechanical piping applications. Built from black malleable iron and rated at 150 lb, this fitting provides a durable right-angle change of direction while stepping down from a 1-inch female NPT inlet to a 3/4-inch female NPT outlet. Malleable iron construction gives the fitting the ductility to handle installation stress and minor mechanical shock without cracking, making it a reliable choice in both new construction and retrofit work. Licensed plumbers and pipefitters are the primary installers.

This elbow is suited for use in low-pressure steam, gas, air, and water piping systems where a 90-degree direction change and a pipe size reduction are needed at the same fitting location. The black finish indicates no galvanization, which is standard practice for natural gas and propane piping systems, as well as general industrial and mechanical service lines. It is commonly installed in residential gas supply lines, commercial HVAC hydronic systems, compressed air distribution, and similar threaded piping networks where a 150 lb class malleable iron fitting meets the required pressure rating.

Key Features

• Reduces from 1-inch to 3/4-inch in a single fitting, eliminating the need for a separate reducer coupling
• 90-degree elbow configuration for right-angle direction changes in threaded pipe runs
• 150 lb pressure class malleable iron construction for durability in steam, gas, air, and water service
• FNPT (female national pipe taper) threads on both ends for standard threaded pipe assembly
• Black finish — no galvanization — appropriate for natural gas and propane piping per applicable codes
• Domestic manufacture for traceability in code-required applications

Compatibility

Designed as an OEM-style and field-replacement malleable iron threaded fitting compatible with standard 1-inch and 3/4-inch NPT threaded pipe in 150 lb class piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes, including IFGC requirements for gas piping applications. Shut off and depressurize the pipe system fully before removing any existing fittings or making new connections. Apply appropriate thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-torque threaded connections, as malleable iron fittings can crack if fitting threads are cross-threaded or assembled with excessive force.
