Product information

Description

INVENA ZO-20-108 is a galvanized steel pipe reducer designed to connect a 4" line to a 3" line. The reducer provides a reliable transition between pipes of different diameters and features a zinc-coated surface for improved resistance to corrosion. It is suitable for use where a secure mechanical or welded connection is required in plumbing, drainage, heating, ventilation and industrial piping systems.

Advantages

The galvanized steel construction offers durability and resistance to rust in moist or exposed environments. A uniform zinc coating reduces maintenance needs and extends service life compared with untreated steel. The simple concentric reduction geometry ensures predictable flow characteristics and minimal turbulence at the joint when installed correctly. Compatibility with standard threaded or welded fittings allows flexible installation methods according to system requirements.

Suitable for

  • Plumbing and drainage systems where diameter reduction from 4" to 3" is required
  • HVAC duct and piping runs that need a secure mechanical transition
  • Industrial process lines with galvanized steel compatibility

Key specifications

  • Material: galvanized steel
  • Connection size: 4" to 3"
  • Coating: zinc galvanization for corrosion resistance
  • Geometry: concentric reducer design for consistent flow
  • Installation: suitable for threaded or welded connections depending on system

How to use

Inspect mating pipe ends to ensure they are clean, square and free of debris before fitting the reducer. Select the appropriate joining method for the system—threaded coupling where compatible, or welding for a permanent joint—following applicable codes and safety practices. Apply sealing compounds or tape if using threaded connections and tighten to the recommended torque. For welded joints, prepare surfaces and use an appropriate welding procedure for galvanized steel to avoid contamination and ensure structural integrity.

Usage recommendations

When installing in systems that carry potable water or process fluids, confirm compatibility of galvanized surfaces with the fluid and local regulations. For outdoor or aggressive environments, periodic inspection is advised to verify the coating remains intact; repair or replace components if significant corrosion appears. Follow manufacturer and local code guidance for welding galvanized materials, including proper ventilation and surface preparation.
