Asc Engineered Solutions 310505805 Black Iron 90 Elbow 2x1.5

Product Description

The ASC ENGINEERED SOLUTIONS 310505805 is a black malleable iron reducing 90-degree elbow rated to Extra Heavy (XH) strength and designed for threaded pipe assemblies in commercial and industrial plumbing systems. The fitting connects a 2-inch female pipe thread (FPT) inlet to a 1.5-inch FPT outlet, allowing a directional change while stepping down pipe diameter in a single fitting. Manufactured to ASTM A-197 material specification and dimensioned to ASME B16.3, this elbow is built for systems where pressure integrity and durability are required. At 3.3 pounds, it is a solid, heavy-duty fitting suited for licensed plumbers and pipefitters working on black iron pipe systems.

This reducing elbow is used in residential and commercial black iron pipe systems, including gas distribution, compressed air, fire protection, and industrial fluid conveyance applications. The XH strength rating makes it appropriate for higher-pressure service compared to standard-weight fittings. The black finish is standard for ferrous pipe work where galvanized coating is not required. Licensed plumbers and pipefitters typically install this fitting as part of threaded pipe assemblies where a 90-degree turn and a pipe size reduction are needed at the same junction point.

Key Features

• Reducing configuration: 2-inch FPT inlet to 1.5-inch FPT outlet in a single 90-degree fitting
• Extra Heavy (XH) strength rating for demanding pressure service
• Malleable iron construction per ASTM A-197 for toughness and thread integrity
• Dimensioned to ASME B16.3 for standardized fit with threaded pipe systems
• Threads conform to ASME B1.20.1 for reliable, leak-resistant connections
• UL and FM listed for use in fire protection and other listed applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for black iron threaded pipe systems using 2-inch and 1.5-inch nominal pipe sizes with NPT threading per ASME B1.20.1.

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) where applicable. Depressurize and isolate the pipe section before cutting into any existing system. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before assembly, and tighten to the fitting using a pipe wrench. Do not over-torque malleable iron fittings, as the material can crack under excessive force.
