Copper coupling KAN-therm Mufa Copper 15 mm (model 2265245001)

KAN-therm Mufa Copper 15 mm is a compact copper coupling designed to join 15 mm copper pipe sections in plumbing and heating installations. The coupling offers a continuous metallic connection suitable for potable water systems, central heating return lines and small hydronic circuits. Intended for soldered or mechanically secured joints, the product provides a permanent, corrosion-resistant link between copper pipe ends while maintaining a minimal profile for use in confined spaces.

Advantages

The coupling is manufactured from copper to ensure good thermal and electrical conductivity, as well as long-term resistance to corrosion in standard water and heating applications. Its 15 mm size makes it compatible with common residential and light-commercial copper piping, allowing for straightforward installation with standard plumbing tools. The compact body reduces the need for additional fittings and provides a reliable sealed joint when properly soldered or mechanically fastened.

Suitable for

• Joining 15 mm copper pipes in potable water distribution
• Central heating return and supply lines in small installations
• Repairs and modifications in hydronic circuits and radiator connections
• Compact spaces where a low-profile metallic coupling is required

Key specifications

• Material: Copper
• Nominal connection size: 15 mm
• Suitable joint methods: Soldering (brazing) or mechanical fastening
• Application media: Potable water, heating fluids compatible with copper
• Typical uses: Plumbing, central heating return/supply, small hydronic circuits

How to use

Prepare copper pipe ends by cutting square, deburring and cleaning the surfaces to be joined. For soldered joints, apply appropriate flux, assemble the coupling and heat until solder flows to form a continuous seal. For mechanical installation, follow the chosen connector or clamp manufacturer’s instructions to secure the coupling and verify leak-tightness. After installation, pressure-test the system according to local codes and standards before putting it into service.

Usage recommendations

Use compatible solder alloys, fluxes and certified mechanical fittings for potable water and heating systems. Observe local plumbing codes, ensure appropriate water treatment to prevent corrosion, and perform pressure testing after installation. When working near other materials, allow for thermal expansion and provide adequate support to avoid stress on joints.
