## Long description

VIEGA copper coupling 22 mm straight coupling (model 100353) is a two-pass copper fitting engineered to join 22 mm copper pipes in plumbing, heating and refrigeration systems. Made from copper to offer corrosion resistance and efficient thermal conductivity, this straight coupling is intended to provide a stable mechanical and leak-tight joint when installed with appropriate joining methods. The product suits potable water circuits, heating lines and other applications where copper pipe connections are required.
Advantages
The coupling’s copper construction delivers reliable corrosion resistance and good heat transfer properties, helping maintain system performance. Its straight two-pass design simplifies alignment of 22 mm copper pipes and reduces the need for additional components. The fitting is compatible with common copper pipe joining techniques and provides a durable, compact connection suitable for confined spaces.
Suitable for
Joining 22 mm copper pipes in potable water distribution
Connecting sections in central heating and radiator circuits
Repairs and replacements in refrigeration and HVAC copper lines
Compact installations where a straight mechanical coupling is required
Key specifications
Material: copper for corrosion resistance and thermal conductivity
Connection type: straight two-pass coupling for continuous pipe alignment
Pipe size compatibility: 22 mm copper pipe
Typical applications: potable water, heating systems, refrigeration and HVAC circuits
How to use
Select the correct 22 mm copper pipe ends, deburr and clean them to remove oxidation and contaminants. Fit the pipes fully into the coupling, ensuring correct alignment, and apply the chosen joining method suitable for copper fittings—such as soldering, brazing or approved mechanical joining technique—following manufacturer and local plumbing regulations. After joining, inspect the joint and perform a pressure or leak test according to system requirements.
Usage recommendations
Use appropriate safety equipment and follow local codes when soldering or brazing. Ensure compatibility of fluxes, solders or sealing materials with potable water if used on drinking water systems. For HVAC and refrigeration applications, confirm the coupling is suitable for the refrigerant and operating pressures in the specific system.
