PPSU compression fitting KAN-therm 18×2.5 (model 9019.26) for plastic and metal-plastic pipes

KAN-therm PPSU compression fitting 18×2.5 (model 9019.26) is a connector designed for joining 18×2.5 mm plastic and metal-plastic pipes in potable water and heating installations. Manufactured from PPSU (polyphenylsulfone), the fitting provides elevated thermal and chemical resistance compared with standard polymer fittings, supporting long-term operation in residential and commercial systems. The compression mechanism ensures a sealed connection without the need for soldering or adhesives.

Advantages

The PPSU construction delivers high mechanical strength and resistance to hot water, chemicals and hydrolysis, while maintaining dimensional stability at elevated temperatures. The compression design enables quick assembly and disassembly, suitable for repairs and renovation works. The fitting is compatible with common 18×2.5 mm plastic and metal-plastic pipes, offering a secure, leak-resistant joint for potable water and heating circuits.

Suitable for

• Potable water distribution systems in residential and commercial buildings
• Heating circuits and radiator connections
• Renovation and repair works where non-soldered connections are required
• Installations with plastic (PEX, PE-RT) and metal-plastic pipes of 18×2.5 mm dimensions

Key specifications

• Material: PPSU (polyphenylsulfone) providing elevated thermal and chemical resistance
• Compatible pipe dimension: 18×2.5 mm plastic and metal-plastic pipes
• Connection type: compression fitting for secure, tool-assisted assembly
• Application: potable water and heating systems
• Operating temperature range: suitable for hot water and heating applications (refer to system design limits)

How to use

Prepare pipe ends by cutting squarely and removing any burrs or debris. Slide the compression nut and sealing elements onto the pipe, insert the pipe fully into the fitting body until it reaches the stop, then tighten the compression nut according to manufacturer torque recommendations to create a secure seal. For disassembly, loosen the compression nut and withdraw the pipe; inspect sealing elements and replace if damaged before reassembly. Follow relevant local plumbing codes and the system designer's specifications during installation.

Usage recommendations

Verify pipe compatibility and wall thickness before installation. Use appropriate tools to ensure uniform tightening without over-torquing. For systems conveying potable water, flush the pipeline after installation and perform pressure tests according to local standards. Replace sealing elements during maintenance if any signs of wear or leakage appear.
