## Summary description

Galvanized reducer fitting by INVENA, model ZO-20-401, with connection dimensions 3/2 x 1/2". Designed to connect pipes or fixtures of differing diameters, providing a durable corrosion-resistant joint for plumbing systems.

## Long description

Invena galvanized reducer fitting 3/2 x 1/2" ZO-20-401 is a metal plumbing adapter designed to join piping or fixtures with different connection diameters. The fitting features a galvanized finish that provides a protective layer against corrosion, making it suitable for use in potable water and heating systems where a reliable transition between 3/2" and 1/2" connections is needed. The component is intended for threaded or compatible tubing connections and offers a compact solution for diameter reduction in residential and light-commercial plumbing installations.
Advantages
The galvanized surface improves resistance to rust and extends service life compared with untreated steel. Its reducer design enables a secure, leak-resistant junction between larger and smaller threaded connections without requiring replacement of existing pipe runs. The fitting is compact and mechanically simple, facilitating straightforward installation and maintenance while maintaining stable flow characteristics through the reduced section.
Suitable for
Connecting a 3/2" pipe or fitting to a 1/2" pipe or fixture
Domestic cold and hot water distribution systems
Heating circuits where a change of thread or tube diameter is required
Repairing or adapting existing plumbing runs during retrofit or renovation
Key specifications
Material: galvanized metal (steel)
Type: reducer fitting for diameter transition
Connection sizes: larger side 3/2", smaller side 1/2"
Surface finish: corrosion-resistant galvanization
Application medium: water and heating fluids
How to use
Prepare the mating threads or tubing by cleaning and removing debris or old sealant. Apply an appropriate thread sealant or tape to the male thread if required by the installation standards. Hand-start the fitting onto the mating thread, then tighten with a wrench until snug and secure, taking care not to overtighten and damage the threads or compress the galvanization. After installation, inspect the joint under pressure and check for leaks; retighten slightly if necessary following manufacturer or installer torque guidance.
Usage recommendations
Use the fitting in systems compatible with galvanized steel and ensure water chemistry will not accelerate corrosion. For potable water systems, follow local plumbing codes regarding use of galvanized components. When combining dissimilar metals, employ dielectric unions or appropriate isolation methods to prevent galvanic corrosion.
