Compression Fitting KAN-therm 14x2 PPSU model 9019.23 for PEX and multilayer pipes

KAN-therm compression fitting 14x2 PPSU model 9019.23 is a push-fit coupling designed for secure connection of 14x2 PEX and compatible multilayer pipes. Manufactured from PPSU (polyphenylsulfone), the fitting offers resistance to elevated temperatures and common plumbing chemicals, making it suitable for domestic water supply and light commercial heating systems. The compact design fits standard 14x2 pipe dimensions and enables reliable, leak-resistant joints when installed according to recommended procedures.

Advantages

The PPSU construction provides high mechanical strength and long-term dimensional stability across a wide temperature range. The compression-style connection simplifies installation by eliminating the need for soldering or solvent welding, while still ensuring a tight seal. The fitting is corrosion-resistant and compatible with PEX and approved multilayer pipes, reducing the number of different components required on site.

Suitable for

• Domestic potable water distribution with 14x2 PEX pipes
• Underfloor heating manifolds and branch connections in light commercial settings
• Repair and extension of existing PEX or compatible multilayer piping systems
• Applications requiring chemical and temperature-resistant plastic fittings

Key specifications

• Connection type: compression/push-fit for 14x2 pipe dimensions
• Material: PPSU (polyphenylsulfone)
• Compatible pipe types: PEX and approved multilayer pipes
• Suitable application: potable water and heating systems
• Operating temperature: suitable for typical domestic hot water and heating temperatures (refer to system design limits)
• Corrosion resistance: inherent to polymer construction

How to use

Prepare the pipe by cutting it squarely and deburring the end to ensure a smooth insertion. Slide the fitting onto the prepared 14x2 pipe until it seats firmly; follow any manufacturer guidance for insertion depth. Ensure the pipe and fitting surfaces are clean and free of damage before assembly. After making the connection, verify alignment and, where applicable, pressure test the circuit according to local codes and installation practices to confirm a leak-free joint.

Usage recommendations

Use with pipes and accessories approved for compatibility with PPSU fittings and rated for the intended temperature and pressure. Avoid excessive bending stress near the joint and follow system manufacturer's guidelines for maximum operating temperatures and pressures. Periodically inspect accessible joints as part of routine system maintenance.
