## Long description

INVENA reducing fitting 3 x 3/2" zinc-plated (model ZO-20-755) is a metal threaded reducer designed to connect pipe sections or fittings with different thread diameters, reducing from a larger 3" thread to a 3/2" thread. The zinc-plated surface provides basic corrosion resistance and a durable finish suitable for use in plumbing and heating systems where a threaded reduction is required. The design ensures a compact, mechanically strong joint for metal pipe assemblies.
Advantages
The zinc-plated steel construction offers enhanced durability compared with untreated metal and helps protect the fitting against surface corrosion in typical indoor installations. Threaded connections provide a secure mechanical join that can be assembled and disassembled for maintenance without specialized tools. The reducer’s straightforward geometry and standard thread sizes make it compatible with common plumbing and heating components, supporting reliable flow transition between different pipe diameters.
Suitable for
 Plumbing systems requiring threaded reduction between 3" and 3/2" connections
 Heating systems and radiators where threaded adaptors are needed
 Repair or modification of existing metal pipework
 Temporary or permanent installations where dismountable threaded joints are preferred
Key specifications
 Material: zinc-plated steel
 Threaded dimensions: larger thread 3", reduced thread 3/2"
 Connection type: male/female threaded reducer (threaded ends for mechanical joining)
 Surface finish: zinc plating for corrosion resistance
 Application area: plumbing and heating systems
How to use
Ensure mating threads are clean and free of debris before assembly. Apply a suitable thread sealant or PTFE tape to the male threads according to the requirements of the system and local codes. Hand-start the threads to avoid cross-threading, then tighten with appropriate wrenches until a secure, leak-tight joint is achieved without over-torquing. When installing in pressurized systems, perform a pressure test after assembly and check for leaks.
Usage recommendations
Use this zinc-plated reducer indoors or in environments where zinc plating provides adequate protection; avoid prolonged exposure to aggressive outdoor conditions or highly corrosive media without additional protection. Select compatible thread sealants and follow local plumbing regulations during installation. For applications involving potable water, verify suitability of materials for drinking water contact where required.
