KAN-therm compression tee PPSU 25x3.5/14x2/25x3.5 – 9018.740, plumbing fitting

KAN-therm compression tee PPSU 25x3.5/14x2/25x3.5 is a three-branch plumbing fitting designed to join pipes of two different outer diameters using compression connections. Manufactured from PPSU (polyphenylsulfone), the fitting resists chemicals and elevated temperatures, making it suitable for potable water and heating systems. The compression tee provides a compact, non-welded solution for creating branch-offs, repairs or new installations in residential and commercial plumbing networks.

Advantages

The PPSU material ensures good dimensional stability, chemical resistance and sustained performance at higher temperatures compared with many standard plastics. Compression connection design enables tool-free assembly of compatible pipes and creates a secure, leak-resistant joint when installed according to instructions. The compact geometry of the tee facilitates neat installations in confined spaces and reduces the need for additional adapters when connecting pipes of 25 mm and 14 mm diameters.

Suitable for

• Branching potable water supply lines
• Minor repairs and retrofits in heating and domestic plumbing
• Pipework installations in apartments, houses and small commercial premises
• Connections where chemical resistance and elevated temperature tolerance are required

Key specifications

• Material: PPSU (polyphenylsulfone)
• Connection type: compression joints
• Branch sizes: two runs of 25 mm (wall thickness 3.5 mm) and one branch of 14 mm (wall thickness 2 mm)
• Application: potable water and heating systems
• Design: three-branch tee for joining two pipe diameters
• Installation orientation: suitable for horizontal and vertical runs

How to use

Prepare pipes by cutting squarely and deburring the ends. Ensure pipe outside diameters and wall thicknesses match the specified 25x3.5 and 14x2 dimensions. Slide the compression nut and sealing elements (as supplied) onto the pipe ends, insert each pipe fully into the fitting until it seats, then hand-tighten followed by the recommended torque with appropriate tools if indicated by the manufacturer. Verify alignment and test the system for leaks at working pressure and temperature before burying or concealing the connection.

Usage recommendations

Use only pipes and sealing inserts compatible with PPSU compression fittings and observe manufacturer installation torque and pressure/temperature limits. Avoid exposing the fitting to aggressive solvents or sustained mechanical stress beyond normal plumbing loads. Periodically inspect accessible joints as part of routine plumbing maintenance.
