Asc Engineered Solutions 818908857 Malleable Bushing 4x2.5 in

Product Description

The ASC Engineered Solutions 818908857 is a black malleable iron reducing bushing used to transition pipe threads from a larger nominal size to a smaller one within threaded piping assemblies. At 4 inches by 2.5 inches, this bushing handles a common reduction step found in commercial and industrial pipe systems. The black coating provides corrosion resistance suitable for low-pressure gas, air, and water distribution lines. Licensed plumbers and pipefitters install this fitting as part of threaded iron pipe assemblies in mechanical rooms, utility spaces, and process piping runs.

This reducing bushing is suited for threaded iron pipe installations in residential and commercial settings where a 4-inch to 2.5-inch reduction is required. Typical applications include branch reductions in black iron gas distribution lines, compressed air headers, and general industrial piping systems. The malleable iron construction allows the fitting to withstand mechanical stress and vibration better than cast iron alternatives, making it a practical choice for occupied mechanical spaces.

Key Features

• 4-inch by 2.5-inch reduction accommodates a common pipe size transition in threaded assemblies
• Black coating provides corrosion resistance for gas, air, and water service
• Malleable iron construction resists mechanical stress and vibration
• Threaded design for straightforward installation with standard pipe wrenches
• Import construction meeting standard dimensional requirements for malleable iron fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 4-inch to 2.5-inch threaded black iron pipe systems in gas, air, and general plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and IFGC code requirements. Shut off all gas or fluid supply and depressurize the line before removing or installing any threaded fitting. Apply thread sealant or PTFE tape rated for the intended service medium before threading the bushing into place. Use appropriate pipe wrenches and avoid over-tightening, which can crack malleable iron fittings.
