Press-fit coupling Comap MultiSkin PPSU 26 — PPSU plumbing fitting Ø26 mm

Comap MultiSkin PPSU 26 is a press-fit coupling manufactured from PPSU (polyphenylsulfone) designed for use with Ø26 mm plastic and multilayer pipes in drinking water and heating systems. The coupling provides a compact, corrosion-resistant joint that is compatible with standard press tools and delivers a reliable, leak-resistant connection suitable for both residential and commercial piping installations.

Advantages

The PPSU material ensures high chemical and thermal resistance while maintaining mechanical strength and long-term durability. The press-fit design allows for quick assembly without soldering or adhesives, reducing installation time and the risk of thermal damage to surrounding materials. The compact form factor and smooth internal bore minimize flow disturbance and scaling risk, supporting stable hydraulic performance over time.

Suitable for

• Drinking water supply lines
• Heating and radiator connections
• Renovation and new-build plumbing systems
• Residential and light commercial installations

Key specifications

• Material: PPSU (polyphenylsulfone)
• Compatible pipe outside diameter: 26 mm
• Connection type: press-fit coupling for press tools
• Application medium: potable water and heating fluids
• Corrosion resistance: high (non-metallic material)
• Operating temperature: suitable for typical hot water and heating system temperatures

How to use

Verify that the pipe OD is 26 mm and cut the pipe squarely. Deburr and clean the pipe end to remove any particles, oils or protective coatings. Insert the pipe fully into the coupling until it seats against the stop. Use an appropriate press tool and jaw sized for Ø26 mm press fittings to make the press connection following the press tool manufacturer’s instructions. After pressing, visually inspect the joint for correct compression and alignment and, where required, perform a pressure test according to applicable standards and local regulations.

Usage recommendations

Store fittings in a dry, temperature-stable environment away from direct sunlight. Use press jaws and tooling recommended for PPSU press fittings and avoid overheating the fitting during any nearby heat-based work. For permanent installations carrying potable water, follow local codes for flushing and disinfection after system assembly.
