VIEGA transition elbow 90° 22 mm x 3/4" copper-brown (115623)

VIEGA transition elbow 90° 22 mm x 3/4" copper-brown (115623) is a right-angle fitting engineered to connect 22 mm tubing to a 3/4" threaded pipe or component. The fitting provides a compact directional change in plumbing systems while maintaining a reliable mechanical connection between different pipe types or sizes. It is intended for use in potable water and heating systems where a stable 90° transition is required.

Advantages

The fitting offers a space-saving right-angle connection that reduces the need for excessive pipe bending. Its design ensures a secure transition between 22 mm tubing and a 3/4" thread, facilitating straightforward installation and alignment. The copper-brown finish provides corrosion resistance suitable for common domestic and commercial water and heating applications. The robust construction supports long-term mechanical stability in pressurized systems.

Suitable for

• Connecting 22 mm copper or compatible tubing to 3/4" threaded valves and fixtures
• Potable water distribution systems in residential and commercial buildings
• Hot water and heating circuit connections where a 90° change of direction is needed
• Tight installation spaces requiring compact elbow fittings

Key specifications

• Connection A: 22 mm tube
• Connection B: 3/4" external/internal thread (as applicable for system component)
• Angle: 90° right-angle elbow
• Material/finish: copper-brown surface suitable for plumbing use
• Application: potable water and heating systems

How to use

Prepare the 22 mm tubing by ensuring the cut is square and the pipe end is deburred and clean. Apply the appropriate joining method compatible with the tubing (for example press-fitting, soldering or as specified by the piping system) and align the fitting so the 3/4" threaded end engages the mating component. Tighten the threaded connection to the recommended torque for the specific valve or fixture. Verify alignment and secure the pipe supports to minimize stress on the elbow and connected joints.

Usage recommendations

Confirm compatibility of the 22 mm tubing material and the 3/4" threaded component with the fitting’s finish and intended application. Use correct installation tools and follow local plumbing codes. Inspect joints for leaks after pressure testing and provide adequate support to prevent mechanical strain on the elbow in hot water and heating systems.
