Asc Engineered Solutions 818907057 Black Malleable Bushing

Product Description

The ASC ENGINEERED SOLUTIONS 818907057 is a black malleable iron threaded bushing designed to reduce a 1-1/4-inch female pipe thread to a 3/4-inch male pipe thread. Malleable iron construction provides the ductility and impact resistance needed in mechanical piping systems, making this bushing suitable for gas, air, and low-pressure fluid distribution lines. The black coating offers corrosion resistance for dry or mildly corrosive environments. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting as part of threaded iron pipe assemblies in both new construction and retrofit work.

This bushing is used in residential and light commercial piping systems where a pipe diameter reduction is required within a threaded iron pipe run. Common applications include natural gas supply lines, compressed air distribution, and hydronic heating systems. It threads directly into a 1-1/4-inch female fitting while accepting 3/4-inch male pipe on the outlet side, making it a standard transition component in branch or run reductions.

Key Features

• Malleable iron construction for durability and impact resistance in threaded piping systems
• Black coating suitable for gas and air service in non-corrosive environments
• 1-1/4-inch female inlet to 3/4-inch male outlet thread configuration
• Standard hex-style bushing profile for wrench installation
• Lightweight at 0.36 pounds per unit for easy handling and inventory

Compatibility

Designed as an OEM-style replacement or standard component for threaded black malleable iron pipe systems using 1-1/4-inch and 3/4-inch NPT fittings.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable code requirements such as the IFGC or IPC depending on service type. Shut off gas or fluid supply and relieve system pressure before disassembling any threaded fittings. Apply an appropriate thread sealant or tape rated for the intended service medium to all male threads before assembly. Do not overtighten malleable iron fittings, as excessive force can crack the casting.
