Suitable for joining 4-inch to 2-inch threaded or socketed lines where a diameter transition is required.

## Long description

Galvanized reducing pipe fitting INVENA ZO-20-106, 4" x 2" (reducer coupling) is a metal reducer designed to connect pipes of different diameters. The fitting has a zinc-coated surface that increases corrosion resistance and extends service life in standard plumbing, heating and industrial piping applications. It enables a reliable mechanical transition between a 4-inch line and a 2-inch line, suitable for threaded or socketed connections where a change of bore is required.
Advantages
The galvanized finish provides corrosion protection and reduces maintenance needs compared with untreated steel. Its robust metal construction ensures mechanical strength and stability under typical operating pressures in domestic and light industrial systems. The reducer coupling offers a compact footprint, making it suitable for installations with limited space while maintaining secure pipe alignment. Installation is straightforward and compatible with common plumbing techniques for threaded or socket connections.
Suitable for
Plumbing systems requiring diameter transition from 4" to 2"
Heating and radiator installations with mixed pipe sizes
Industrial piping where a durable metal reducer is needed
Repair and retrofit projects involving existing threaded or socketed lines
Key specifications
Material: metal with zinc galvanization for corrosion resistance
Connection type: reducer coupling suitable for threaded or socketed joints
Nominal diameters: 4 inches to 2 inches transition
Shape: concentric reducer profile for aligned pipe transition
Typical applications: plumbing, heating and light industrial piping
How to use
Prepare both pipe ends by ensuring threads or sockets are clean and free of debris. Apply appropriate sealing compound or tape for threaded joints if required by the installation practice. Align the reducer coupling concentrically between the 4" and 2" pipes and engage the threads or fit into sockets according to the connection type. Tighten securely using suitable tools while avoiding over-torquing that could damage threads or deform the fitting. After installation, inspect joints for leaks and verify mechanical stability under operating conditions.
Usage recommendations
Use compatible sealing materials and follow local plumbing codes. For environments with aggressive corrosion agents or where higher chemical resistance is needed, consider materials with specialized coatings or alternative alloys. Periodically inspect the galvanized surface for wear and recheck tightness after the system has been pressurized and cycled.
