Coupler KAN-therm Copper Gas 22 mm (Mufa) for gas installations

The KAN-therm Copper Gas 22 mm coupler (mufa) is a straight copper fitting created for joining 22 mm copper gas pipes in residential and commercial gas distribution systems. Designed to provide mechanical continuity and a gas-tight connection when installed according to applicable local regulations and codes, this coupling is intended for new installations, repairs and extensions of existing copper gas lines. The product name and material reflect suitability for use in gas installations where copper piping is specified.

Advantages

The coupler is manufactured from copper, offering good corrosion resistance and long-term dimensional stability in typical gas service conditions. Its straight design simplifies alignment of pipes and supports reliable mechanical coupling. The component is compatible with standard 22 mm copper gas pipes and is suitable for both concealed and exposed installations when installed by qualified personnel following local safety standards.

Suitable for

• Joining two 22 mm copper gas pipes in residential gas supply circuits
• Repairs and extensions of existing copper gas lines
• Commercial gas distribution systems using 22 mm copper piping
• Applications where a straight, mechanically robust copper coupling is required

Key specifications

• Material: copper
• Connection type: straight coupler for 22 mm copper pipe
• Nominal pipe diameter: 22 mm
• Intended medium: natural gas and other gaseous fuels where copper is permitted
• Placement: suitable for concealed or exposed installations per local code

How to use

Install the coupler only on clean, de-burred 22 mm copper pipe ends. Ensure proper pipe alignment and full insertion depth before making the joint. Final assembly method should comply with the installation practice required for copper gas fittings in your jurisdiction (for example mechanical compression, brazing or soldering where allowed); use approved joining techniques and qualified personnel. After assembly, perform pressure and leak tests as required by local regulations to confirm gas-tightness and system integrity.

Usage recommendations

Use the coupler within systems designed for copper gas piping and follow local codes regarding allowable materials and joining methods. Avoid using copper couplers in systems where copper is not permitted for the conveyed gas or environmental conditions. For safety, installation and testing should be carried out by certified gas installers.
