## Long description

INVENA galvanized reducing fitting 3 x 5/4" (model ZO-20-754) is a metal pipe reducer designed to join pipes of different diameters in plumbing and heating systems. The fitting features a galvanized corrosion-resistant coating that increases durability in domestic and commercial installations. It is manufactured for mechanical connections where stable sealing and structural strength are required.
Advantages
The galvanized surface provides protection against rust and extends service life in wet environments. The reducer enables a secure mechanical transition between a 3" and a 5/4" pipe without welding, simplifying repair and installation tasks. The metal construction ensures mechanical rigidity and resistance to pressure fluctuations common in water and central heating systems.
Suitable for
Domestic water supply lines
Central heating systems
Repair and maintenance of plumbing networks
New construction pipe routing where diameter reduction is required
Key specifications
Material: metal with galvanized coating for corrosion resistance
Connection type: reducing fitting for direct mechanical joining of differing pipe diameters
Dimensions: connects 3" to 5/4" pipe sizes
Suitable media: potable water and heating fluids (where compatible with galvanized surfaces)
Typical applications: pressure-resistant plumbing and heating installations
How to use
Prepare pipe ends by cleaning threads or joining surfaces and remove debris or old sealant. Apply appropriate sealing material (thread tape or compatible joint compound) if using threaded connections, and assemble the reducer by hand-tightening followed by a controlled wrench finish to obtain a leak-free mechanical joint. Ensure alignment and support of connected pipes to avoid undue stress on the fitting. After installation, perform a pressure test according to system requirements to confirm tightness.
Usage recommendations
For long-term performance, avoid exposure to aggressive chemicals that can degrade galvanized coatings; when used in systems with corrosive media, consider material compatibility. Follow local plumbing codes and use appropriate sealing products compatible with galvanized metal. Periodic inspection of joints in heating systems is recommended to detect any signs of corrosion or leakage early.
