Press-fit repair sleeve Comap MultiSkin 20 mm brass/zinc model 7500W20 for pipe connection

Comap MultiSkin press-fit repair sleeve 20 mm (brass/zinc model) is a compact connection fitting engineered to restore and join 20 mm pipes in plumbing and heating systems. Designed for use with standard press tools, this repair sleeve provides a mechanical and hydraulic seal in a small footprint, enabling on-site repairs, replacements and system modifications without the need for soldering or welding.

Advantages

The brass/zinc construction combines corrosion resistance and mechanical strength appropriate for potable water and heating applications. The press-fit design allows rapid installation with consistent joint quality using compatible pressing tools and jaws. Its compact size and simple geometry make it suitable for tight spaces and quick interventions while maintaining a reliable sealed connection under normal operating pressures.

Suitable for

• Repairing damaged sections of 20 mm copper or multi-layer composite pipes
• Joining short pipe segments when replacing valves or fittings
• On-site emergency repairs in residential plumbing and heating systems
• Applications requiring a mechanical press-fit connection without soldering

Key specifications

• Nominal pipe size: 20 mm
• Material: brass body with zinc components
• Connection type: press-fit repair sleeve for press tool installation
• Application: plumbing and heating systems for mechanical and hydraulic sealing
• Design: compact sleeve suitable for confined spaces

How to use

Ensure the pipe ends to be joined are clean, cut square and free from burrs or deformation. Slide the repair sleeve over the pipe ends so that both ends are fully inserted to the sleeve’s stops. Select the appropriate pressing jaws for 20 mm fittings and operate the press tool according to the tool manufacturer's instructions to form the permanent press connections on both sides of the sleeve. Verify the pressed joints visually and, where applicable, perform a pressure test in line with local standards to confirm hydraulic tightness.

Usage recommendations

Use only compatible press tools and jaws rated for 20 mm press fittings. Avoid excessive mechanical stress on newly pressed joints for the duration recommended by relevant installation standards and allow pressure testing to be carried out following local regulatory procedures. Where system media or temperatures fall outside standard potable water or domestic heating ranges, consult material compatibility guidelines before installation.
