KAN-therm PPSU Ultraline coupling 20 mm (model 2566042002)

The KAN-therm PPSU Ultraline coupling 20 mm is a straight pipe connector manufactured from polyphenylsulfone (PPSU) for plumbing and heating systems. Designed to join plastic or composite pipes, this coupling provides a corrosion- and chemical-resistant connection with elevated temperature tolerance. The product is intended for potable water, heating circuits and general service installations where a compact, robust and thermally stable fitting is required.

Advantages

The coupling combines the mechanical strength and long-term dimensional stability of PPSU with resistance to hot water and common chemicals found in building systems. Its compact straight design simplifies alignment and installation in tight spaces. The material properties reduce risk of scale and corrosion compared with metallic fittings, while delivering reliable performance over a wide temperature range typical for domestic and commercial heating and supply systems.

Suitable for

• Potable water distribution in residential and commercial buildings
• Heating circuits, including radiators and underfloor heating manifolds
• Service installations and repairs where plastic or composite pipes are used
• Applications requiring chemical and temperature-resistant pipe joints

Key specifications

• Material: polyphenylsulfone (PPSU)
• Connection type: straight coupling for 20 mm pipe
• Compatibility: designed for plastic and composite piping systems
• Performance: chemical-resistant and suitable for elevated temperature operation
• Design: compact form factor for tight installation spaces

How to use

Prepare the pipe ends by cutting squarely and deburring to ensure full insertion. Slide the coupling onto the prepared pipe ends according to the pipe system manufacturer’s instructions, ensuring correct seating and alignment. Use compatible joining method recommended for PPSU fittings in the respective piping system (for example, press-fit, solvent-free push-fit or other approved mechanical joining technique). After installation, inspect the joint for proper engagement and perform a pressure test in line with local regulations and system requirements.

Usage recommendations

For durable, leak-free connections, follow the pipe manufacturer's preparation and joining guidelines and verify material compatibility with any fluids or additives in the system. Ensure installations are performed at ambient and system temperatures within the material’s rated limits and conduct pressure testing before commissioning.
