Reducing press-fit tee Comap MultiSkin PPSU 16 x 20 x 16

Reducing press-fit tee Comap MultiSkin PPSU 16 x 20 x 16 is a compact press-fitting designed to connect three plastic or multilayer pipes where a branch of smaller diameter is required. Made from PPSU (polyphenylsulfone) and compatible with press-fit installation methods, this fitting provides a reliable transition between 20 mm and 16 mm pipe runs for potable water and heating systems. The component is intended for indoor plumbing and heating applications where a secure, low-profile junction is needed.

Advantages

The MultiSkin design offers a compact footprint and consistent wall thickness to facilitate even pressing and a durable seal. PPSU material delivers good mechanical strength, heat resistance, and long-term hydrolytic stability suitable for potable water and heating circuits. The press-fit connection method minimizes installation time and the need for open flame or solvent welding, reducing on-site complexity and potential fire hazards.

Suitable for

• Domestic potable water distribution with 16 mm and 20 mm plastic or multilayer pipes
• Low-temperature heating circuits and radiator branches
• Compact installations where space for fittings is limited

Key specifications

• Material: PPSU (polyphenylsulfone)
• Connection type: press-fit
• Pipe diameters: 16 mm × 20 mm × 16 mm (reducing tee)
• Application: potable water and heating systems
• Design: MultiSkin compact configuration for consistent pressing

How to use

Prepare the pipes by cutting squarely and deburring the ends to ensure a clean, even surface. Mark the insertion depth on each pipe according to the fitting's specification, fully insert the pipe ends into the press-fit sockets, and verify alignment. Use a compatible pressing tool and jaws sized for the 16 mm and 20 mm connections to perform the press operation in a single cycle per joint. After pressing, visually inspect the crimped zones and perform a pressure test according to applicable regulations to confirm leak-tightness.

Usage recommendations

Use fittings and pressing tools recommended for PPSU MultiSkin systems and perform installation at temperatures and pressures within the manufacturer's allowable range. Avoid use outdoors where prolonged UV exposure may occur, and follow local codes for potable water and heating installations. When in doubt, consult the system documentation or a qualified installer to ensure correct joint preparation and pressing technique.
