Asc 818908808 Black Malleable Iron Bushing 4 X 3 Inch

Product Description

The ASC Engineered Solutions 818908808 is a black malleable iron pipe bushing designed to reduce a 4-inch female fitting down to a 3-inch male thread connection. This hex bushing style fitting is used in threaded pipe assemblies where a reduction in pipe size is needed within the same run. The black coating provides corrosion resistance suitable for gas, air, and water service applications. Weighing 2.92 pounds, it is built to handle the mechanical stress typical of threaded iron pipe systems. Licensed plumbers and pipefitters are the primary installers of this fitting in both new construction and retrofit work.

This bushing is used in residential and commercial piping systems where 4-inch to 3-inch threaded reductions are required. Common applications include natural gas distribution, compressed air lines, and non-potable water systems. It is installed wherever the line size must step down between two threaded components such as valves, tees, or couplings. The black finish makes it a standard choice for gas piping applications governed by IFGC and local mechanical codes.

Key Features

• 4-inch female to 3-inch male threaded reduction in a single fitting
• Black coating suitable for gas, air, and industrial piping service
• Malleable iron construction provides strength and impact resistance in threaded assemblies
• Weighs 2.92 pounds for a solid, full-size hex bushing profile
• Import-sourced fitting for cost-effective inventory in high-volume applications

Compatibility

Designed as a standard NPT-threaded malleable iron hex bushing for use in 4-inch to 3-inch threaded pipe systems across gas, air, and water service applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IFGC or IPC requirements. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply appropriate thread sealant or tape rated for the service type before threading the bushing into the female fitting. Do not over-tighten; use a pipe wrench to achieve a firm, leak-free connection without cracking the fitting.
