Asc Engineered Solutions 310505607 Malleable Iron 90 Elbow

Product Description

The ASC Engineered Solutions 310505607 is a black malleable iron 90-degree elbow fitting rated to Extra Heavy (XH) strength. It features female pipe thread (FPT) connections on both ends and is designed for use in threaded black iron piping systems. Manufactured to ASTM A-197 and dimensioned to ASME B16.3, this fitting provides a reliable directional change in piping runs where strength and pressure integrity are required. The reducing configuration accepts a 1.5-inch connection on one end and a 1-inch connection on the other, making it suitable for transition points within a system. Licensed plumbers and pipefitters are the primary installers.

This elbow is used in residential and commercial plumbing and mechanical piping systems, particularly black iron gas distribution lines, compressed air runs, and steam or hydronic applications where malleable iron fittings are specified. The XH rating makes it appropriate for higher-pressure service conditions. UL and FM listed, it meets the approval requirements for gas piping installations in many jurisdictions. The black finish is standard for gas service applications and distinguishes it from galvanized fittings used in water service.

Key Features

• Extra Heavy (XH) strength rating for higher-pressure applications
• Malleable iron construction per ASTM A-197 for toughness and machinability
• Dimensioned to ASME B16.3 for industry-standard fitment
• Threads conform to ASME B1.20.1 for consistent, leak-resistant makeup
• UL and FM listed for gas piping system use
• Black finish suitable for gas service identification

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded black malleable iron piping systems using 1.5-inch to 1-inch reducing 90-degree elbows per ASME B16.3 specifications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as required by the application. Shut off and depressurize the piping system fully before disassembling or installing any fittings. Apply a thread sealant rated for the service medium before makeup. Do not over-tighten threaded connections with power tools, as this can crack the fitting body.
