Asc 818908378 Black Malleable Bushing 3 in X 1.25 in

Product Description

The ASC ENGINEERED SOLUTIONS 818908378 is a black malleable iron reducing bushing designed for threaded pipe systems in plumbing, mechanical, and industrial piping applications. This bushing reduces a 3-inch female threaded opening down to a 1.25-inch male threaded connection, allowing technicians to transition between pipe sizes within the same run. The black coating provides corrosion resistance suitable for gas, air, and water systems where galvanized fittings are not specified. Malleable iron construction gives this fitting the toughness and ductility required to handle wrench torque and thermal cycling without cracking.

This reducing bushing is used in residential and commercial piping installations where pipe diameter changes are required at tees, crosses, or threaded outlets. Plumbers, pipefitters, and mechanical contractors install this type of fitting during new construction and retrofit work on gas distribution lines, compressed air systems, and black iron pipe assemblies. Its threaded configuration follows standard NPT conventions, making it compatible with standard threaded pipe and fittings of matching size.

Key Features

• Reduces 3-inch female NPT to 1.25-inch male NPT in a single fitting
• Black malleable iron construction for ductility and wrench resistance
• Black coating for corrosion resistance on gas and air piping systems
• Threaded ends conform to standard NPT thread form for broad fitment
• Weighs 1.57 pounds for a solid, full-bodied fitting profile

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded black iron pipe systems in plumbing, gas, and mechanical piping applications.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters working on threaded pipe systems. Shut off and depressurize the pipe system completely before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to male threads before assembly, following local plumbing and mechanical code requirements such as the IPC or IFGC. Do not overtighten with pipe wrenches, as malleable iron threads can strip if excessive force is applied.
