KAN-therm reduction fitting PP 32×20 mm 04108032

KAN-therm reduction fitting PP 32×20 mm is a polypropylene (PP) connector intended to join pipeline sections with different diameters, providing a secure transition from 32 mm to 20 mm. Designed for plumbing and heating systems, the fitting is compatible with PP piping and is suitable for use in potable water and central heating installations where polypropylene components are specified. The compact design and smooth internal bore support stable flow characteristics while reducing turbulence at the diameter change.

Advantages

The KAN-therm PP reduction fitting offers chemical and corrosion resistance typical of polypropylene, low weight for easier handling and installation, and dimensional stability at normal service temperatures of plumbing and heating systems. Its smooth joint surfaces facilitate reliable connections when used with compatible fusion or socket methods, and the fitting delivers a leak-resistant transition between 32 mm and 20 mm pipe runs when installed according to manufacturer guidelines.

Suitable for (tasks / use cases)

• Reducing pipeline diameter from 32 mm to 20 mm in potable water distribution.
• Transitions within central heating circuits where PP fittings are specified.
• Domestic and light-commercial plumbing repairs or new installations using polypropylene pipework.
• Retrofitting or branching smaller supply lines from larger mains in closed systems.

Key specifications

• Material: Polypropylene (PP)
• Connection type: Reduction fitting for joining 32 mm to 20 mm pipes
• Primary applications: Potable water systems and central heating circuits
• Design: Smooth internal bore to minimise flow disturbance
• Compatibility: For use with PP pipe systems and compatible fusion/socket joining methods

How to use

Install the KAN-therm PP reduction fitting by preparing pipe ends to the required length, ensuring they are clean, squared and free of grease or debris. Use the appropriate joining method for the system—such as thermal fusion, socket welding or the recommended mechanical joint—following industry best practices and the pipe manufacturer's instructions. Insert pipes fully into the fitting to the marked stop, allow joints to cool or set where applicable, and test the assembled pipeline under pressure to verify leak-free performance before commissioning.

Usage recommendations

Use this fitting only in systems designed for polypropylene components and within the operating temperature and pressure limits specified by the piping system manufacturer. Verify chemical compatibility if aggressive fluids are present and follow local plumbing codes and standards for potable water and heating installations. For long-term reliability, ensure correct joining technique and periodic inspection after installation.
