Pipe reducer Opal Type N4 galvanized 1½" to 3/4"

Galvanized pipe reducer Opal Type N4 1½" to 3/4" is a metal fitting designed to join pipes of different diameters in plumbing, heating and industrial fluid systems. The reducer connects a 1½-inch inlet to a 3/4-inch outlet, providing a secure transition between larger and smaller piping. A zinc-based protective coating increases resistance to corrosion, making the fitting suitable for indoor and outdoor installations where threaded or socketed connections are used according to system requirements.

Advantages

The galvanized surface delivers enhanced protection against rust and environmental wear while maintaining mechanical strength for pressure-bearing connections. The Opal Type N4 reducer features straightforward geometry for reliable sealing with compatible threads or sockets and is manufactured to provide consistent dimensional accuracy for easy installation and replacement. Its metal construction supports repeated assembly and disassembly without significant deformation.

Suitable for

• Plumbing systems requiring diameter transition from 1½" to 3/4"
• Heating and radiator connections with mixed pipe sizes
• Industrial fluid lines where corrosion resistance is required
• Indoor and outdoor installations with threaded or socket connections

Key specifications

• Material: galvanized metal with zinc coating
• Inlet diameter: 1½ inch (1.5")
• Outlet diameter: 3/4 inch (0.75")
• Connection type: suitable for threaded or socketed fittings depending on system
• Application: plumbing, heating, industrial fluid lines
• Corrosion protection: zinc coating for indoor and outdoor use

How to use

Select the reducer that matches the pipe diameters and connection type of your system. Prepare pipe ends by cleaning threads or sockets and apply appropriate thread sealant or tape if required by the installation. Screw or insert the reducer into the larger pipe fitting and then attach the smaller pipe to the outlet, ensuring alignment and tightening to the manufacturer-recommended torque for the connected materials. After assembly, pressurize the system gradually and inspect joints for leaks before returning to normal operation.

Usage recommendations

Use compatible thread sealants or tapes rated for the transported fluid and operating temperature. For outdoor or highly corrosive environments, periodically inspect the galvanized coating and joints for signs of wear and reapply protective measures if necessary.
