Pipe reducer VIEGA 42 x 22 mm copper (gas) polished

VIEGA pipe reducer 42 x 22 mm in polished copper designed for gas installations. This coupling provides a reliable transition from a 42 mm pipe to a 22 mm pipe and is intended for use in gas piping systems where a durable copper fitting is required. The polished copper finish reduces surface oxidation and offers smooth mating with compatible copper pipes and fittings.

Advantages

The reducer is manufactured from copper for good corrosion resistance and thermal stability in gas applications. Its polished surface facilitates clean connections and simplifies visual inspection. The compact, single-piece design ensures a consistent internal bore for minimal flow disturbance and straightforward installation by trained professionals.

Suitable for

• Reducing pipe diameter in natural gas and LPG distribution lines
• Transitions between different copper pipe sizes in residential and commercial gas systems
• Repair or modification work where a permanent copper coupling is required

Key specifications

• Material: copper
• Connection sizes: 42 mm to 22 mm
• Surface finish: polished copper
• Application: gas piping systems
• Design: straight concentric reducer for direct diameter transition

How to use

Prepare both pipe ends by cleaning and deburring to ensure full contact with the reducer. Use the appropriate joining method for copper gas fittings as specified by local codes and the installer’s practice (for example, soldering/brazing or approved mechanical joining systems). Verify alignment and support of the pipes to prevent stress on the joint. After installation, perform leak testing in accordance with applicable gas safety regulations.

Usage recommendations

Install only with compatible copper pipe and fittings and in accordance with local gas installation standards. Ensure that a qualified installer carries out joining and leak testing. Avoid mixing dissimilar metals without appropriate corrosion protection or dielectric isolation.
