Flat galvanized pipe fitting 3" INVENA ZO-41-075

Flat galvanized pipe fitting 3" INVENA ZO-41-075 is a zinc-coated flange-style connector engineered for use with three-inch pipe systems. It provides a flat mating surface for mechanical joints in plumbing, heating, ventilation and air conditioning installations. The galvanized finish reduces corrosion risk and extends service life when used in typical indoor and sheltered outdoor environments.

Advantages

This flat galvanized pipe fitting offers a durable zinc-coated surface that resists rust and provides consistent mechanical strength at the joint. Its flat flange design simplifies alignment and compression between mating components, helping to form a stable, low-profile connection. Manufactured to suit standard three-inch piping, the fitting is suitable for repair, replacement or new installations where a flat flange-style interface is required.

Suitable for

• Plumbing systems requiring a flat flange connection for 3" pipes
• HVAC and ventilation ducts with mechanical joint requirements
• Repair and replacement of worn or corroded flange fittings
• Indoor and sheltered outdoor installations where galvanic protection is sufficient

Key specifications

• Compatible pipe diameter: 3 inches (nominal)
• Material finish: zinc-coated (galvanized) surface for corrosion resistance
• Connection style: flat flange mating surface for mechanical joints
• Application: plumbing, heating, ventilation and general pipework

How to use

Prepare mating pipe ends by ensuring faces are clean, free of debris and properly cut to square. Position the flat galvanized fitting against the mating surface and align bolt holes or fastening points if applicable. Use appropriate gaskets, seals or fasteners compatible with galvanized surfaces and the pipe material to secure the joint. Tighten fasteners evenly to achieve a uniform compression across the flat mating surface and verify the connection for leaks before placing the system back into service.

Usage recommendations

For best performance, use the fitting in environments where the zinc coating provides adequate protection; avoid prolonged exposure to highly corrosive chemicals or direct contact with dissimilar metals that can accelerate galvanic corrosion. Inspect joints periodically and replace any fitting showing significant surface degradation. When joining to different materials, use dielectric or insulating gaskets to minimize corrosion risk.
