KAN-therm compression tee PPSU 32x4.4 / 18x2.5 / 25x3.5 model 9018.510

The KAN-therm compression tee PPSU 32x4.4 / 18x2.5 / 25x3.5 model 9018.510 is a three-way mechanical compression fitting manufactured from PPSU (polyphenylsulfone). It is designed to join pipes of three different outer diameters—32 mm (wall 4.4 mm), 18 mm (wall 2.5 mm) and 25 mm (wall 3.5 mm)—providing a durable branch connection for plumbing and heating installations. The PPSU material offers resistance to elevated temperatures and common chemicals used in building services, while the compression design enables secure, leak-resistant joints without the need for hot works or adhesive bonding.

Advantages

The fitting provides a reliable mechanical seal through compression technology, allowing quick installation and straightforward maintenance. PPSU construction ensures high mechanical strength, dimensional stability and resistance to thermal ageing, making it suitable for both potable water and heating circuits. The product supports retrofit and repair tasks as well as new installations where a compact, multi-diameter branch fitting is required.

Suitable for

• Domestic plumbing systems with mixed pipe sizes
• Heating circuits and radiator connections
• Repair and retrofit work in residential and commercial buildings
• Applications requiring chemical and temperature-resistant fittings

Key specifications

• Material: PPSU (polyphenylsulfone)
• Connection type: mechanical compression
• Pipe outer diameters: 32 mm (4.4 mm wall), 18 mm (2.5 mm wall), 25 mm (3.5 mm wall)
• Suitable media: potable water and heating fluids (according to system design)
• Installation environment: residential and commercial plumbing/heating systems

How to use

Select the appropriate pipes with the specified outer diameters and wall thicknesses. Ensure pipe ends are cut square, deburred and clean of any dirt or grease. Insert each pipe fully into the corresponding compression port until it seats against the internal stop. Tighten the compression nut to the recommended torque or hand-tight specification for the system to form a secure seal. After assembly, pressure-test the connected system according to applicable standards to confirm leak-free performance.

Usage recommendations

Use the fitting only with compatible pipe materials and dimensions as stated. Avoid exposing the fitting to aggressive chemicals not compatible with PPSU and follow local codes for potable water and heating systems. Perform a pressure test after installation and inspect periodically for signs of mechanical stress or wear.
