Bronze transition coupling VIEGA 28 x 1 mm model 94343G (MPN 103996)

Bronze transition coupling VIEGA 28 x 1 mm model 94343G is a compact metal connector designed to join pipes or fittings with a 28 mm outer diameter and a 1 mm wall/profile. Manufactured from bronze, the coupling offers increased corrosion resistance and mechanical strength compared with many non‑metallic connectors. It is intended for use in plumbing, heating and sanitary installations where a durable metal transition joint is required for reliable flow and leak‑resistant connections.

Advantages

The bronze construction provides good resistance to corrosion in typical potable water and heating environments while maintaining mechanical stability under pressure. The simple cylindrical design ensures straightforward alignment of mating pipes and minimizes the number of components required for a transition. Made to industry machining and material standards, the coupling gives consistent dimensional accuracy for predictable fits and easy installation in retrofit or new‑build situations.

Suitable for

• Joining copper, stainless or other compatible metal pipes with 28 mm outer diameter and 1 mm wall/profile
• Plumbing repairs and retrofits in residential and commercial properties
• Heating system connections and radiator or boiler installations
• Sanitary installations where a metal transition is preferred for strength or longevity

Key specifications

• Material: bronze, suitable for potable water and heating circuits
• Connection size: fits pipes with 28 mm outer diameter
• Wall/profile compatibility: for pipes with approximately 1 mm wall thickness/profile
• Design: straight transition coupling for direct end‑to‑end joining
• Typical installation environment: indoor plumbing, heating and sanitary systems

How to use

Ensure both pipe ends are clean, free of debris and cut squarely. Slide the bronze transition coupling onto one pipe end, align the second pipe for a straight end‑to‑end join and secure according to the system practice in use (for example by soldering, brazing, mechanical compression fittings or approved sealing methods compatible with bronze and the pipe material). Verify correct alignment and service pressure ratings before restoring system pressure. Follow applicable local codes and manufacturer guidance for joint preparation and assembly.

Usage recommendations

Use the coupling in systems that require a metal transition for durability; avoid exposing bronze fittings to aggressive chemical environments not compatible with bronze. Inspect joints after installation and during scheduled maintenance; where dissimilar metals are connected, consider galvanic corrosion mitigation such as dielectric unions or appropriate insulating materials.
