## Summary description

KAN-therm compression coupling for plumbing and heating systems, size 25x3.5/18x2.5 with PPSU body, model 9019.30. Designed to join pipes with outer diameters 25 mm (wall 3.5 mm) and 18 mm (wall 2.5 mm). Provides a mechanical, press-free connection suitable for potable water and heating circuits. Typical use: pipe transitions, repairs, and system extensions.

## Long description

The KAN-therm compression coupling 25x3.5/18x2.5 PPSU model 9019.30 is a mechanical joining fitting designed to connect pipes with outer diameters 25 mm (wall thickness 3.5 mm) and 18 mm (wall thickness 2.5 mm). Constructed with a PPSU body, this compression coupling creates a press-free transition between different pipe sizes for plumbing and heating systems. It is suitable for potable water and heating circuits and is intended for pipe transitions, repairs and system extensions where a reliable, tool-light connection is required.
Advantages
The PPSU body offers good chemical and temperature resistance while maintaining mechanical strength and dimensional stability. The compression design enables a secure connection without the need for soldering or press tools, which simplifies installation and reduces downtime. The coupling accommodates two common pipe wall profiles, allowing straightforward transitions between 25x3.5 and 18x2.5 pipes. Its compact form factor supports installation in confined spaces.
Suitable for
Connecting 25 mm (3.5 mm wall) to 18 mm (2.5 mm wall) pipes
Potable water supply lines
Domestic and small commercial heating circuits
Repairing damaged pipe sections and on-site modifications
System extensions and transitions without press tooling
Key specifications
Material of main body: PPSU (polyphenylsulfone)
Connection type: compression coupling (mechanical, press-free)
Compatible pipe outer diameters: 25 mm and 18 mm
Compatible pipe wall thicknesses: 3.5 mm (for 25 mm OD) and 2.5 mm (for 18 mm OD)
Application: potable water and heating systems
Installation space: compact design for confined areas
How to use
Ensure pipe ends are cut square, clean and free from burrs or debris. Slide the compression nut and sealing components onto each pipe end according to the manufacturer's orientation. Insert the pipe ends fully into the coupling until they meet the internal stops. Hand-tighten the compression nuts and then secure them to the recommended torque using appropriate tools if specified by installation guidelines. After assembly, perform a pressure test of the system in line with local standards to verify leak-free connections.
Usage recommendations
Use this coupling for connections in potable water and heating circuits where chemical resistance and dimensional stability are required. Do not expose the fitting to continuous temperatures beyond the material's rated limits and avoid aggressive chemicals not compatible with PPSU. Follow local plumbing codes and perform pressure testing after installation. For long-term reliability, ensure correct pipe insertion depth and proper tightening of compression elements.
