## Long description

Copper bypass coupling VIEGA 22 mm is a compact copper fitting intended for forming bypass lines and branch connections in potable water and heating systems. Manufactured from copper and designed for compatibility with soldered or press-fit installation methods, this coupling allows reliable connection to copper piping with a nominal diameter of 22 mm. The product is suitable for redirecting flow, creating bypass loops or connecting parallel circuits in residential and commercial plumbing installations.
Advantages
The coupling is made from copper, which provides good thermal conductivity and corrosion resistance in typical potable water and heating environments. Its dimensions and design ensure a tight fit with 22 mm copper pipe, enabling durable mechanical performance when installed by soldering or with compatible press-fit tools. The compact form factor simplifies integration into existing pipe runs and minimizes additional space requirements.
Suitable for
 Creating bypass loops in heating circuits
 Redirecting potable water flow in plumbing systems
 Connecting parallel pipe circuits in residential buildings
 Branching lines in commercial plumbing installations
Key specifications
 Material: copper
 Nominal diameter: 22 mm
 Connection types: compatible with soldered and press-fit installation methods
 Application: potable water and heating systems
 Form: bypass coupling for inline or branch connections
How to use
Prepare the copper pipes by cutting squarely and removing burrs and oxidation to ensure clean contact surfaces. Fit the coupling onto the prepared 22 mm copper pipes and install using the chosen method: soldering requires proper flux application and heating to create a leak-free joint, while press-fit installation requires a compatible pressing tool and jaws suitable for the coupling profile. After installation, visually inspect joints for correct seating and perform a pressure test according to system requirements before putting the circuit into regular service.
Usage recommendations
Use appropriate personal protective equipment during soldering or pressing operations. Verify compatibility of press-fit tooling and fittings before installation, and follow local plumbing codes and manufacturer instructions for potable water and heating systems. Regular inspection and pressure testing after installation will help ensure long-term reliability.
