Compression Coupling Comap MultiSkin brass/tinned 20 x 1/2 for plumbing connections

Compression coupling Comap MultiSkin brass/tinned 20 x 1/2 is a mechanical press-style coupling designed to join 20 mm (1/2") pipes in potable water and heating systems. Manufactured from brass with a tin-plated surface, the coupling provides a corrosion-resistant connection suitable for both new installations and repairs. The product is intended to form a sealed, load-bearing joint when fitted to compatible copper, multilayer or similarly dimensioned piping using the recommended compression or pressing method.

Advantages

The brass body with tin plating enhances corrosion resistance and extends service life in contact with potable water. The compression-style design enables a compact connection without the need for soldering, reducing installation time and the need for open flame. The coupling is compatible with common 20 mm (1/2") piping dimensions and provides a reliable sealed joint when installed according to manufacturer guidelines.

Suitable for

• Joining 20 mm (1/2") potable water supply pipes
• Repairing or replacing sections of heating system pipework
• Compact plumbing connections in residential and commercial installations
• Applications where corrosion resistance and a press-style joint are required

Key specifications

• Material: Brass with tin plating for improved corrosion resistance
• Nominal pipe size: 20 mm (1/2")
• Connection type: Compression / press mechanical coupling
• Suitable media: Potable water and heating fluids
• Typical application: Pipe joining and repair in plumbing and heating systems

How to use

Ensure pipes are cut squarely and deburred before fitting. Slide the coupling components onto the prepared pipe ends and position the coupling so that both pipe ends are fully inserted to the correct depth. Use the appropriate compression or pressing tool recommended for the coupling type to form the mechanical joint, following the tool manufacturer’s instructions. After installation, verify the connection for correct alignment and test the system at working pressure to confirm there are no leaks.

Usage recommendations

Use with pipes that match the nominal 20 mm (1/2") dimension and with compatible materials (copper, multilayer, or other manufacturer-approved tubing). Avoid installing on damaged or heavily deformed pipe ends. Follow local plumbing codes and perform pressure testing after installation. For long-term performance, periodic inspections are recommended in concealed or high-moisture environments.
