Compression ring 18×2.5 mm for push-fit fittings KAN-therm 9001.80

KAN-therm compression ring 18×2.5 mm is a metal retaining ring engineered for push-fit plumbing and heating fittings. It is intended to fit 18 mm pipes with a 2.5 mm wall thickness and provides reliable mechanical retention for compatible push-fit connectors used in potable water and heating installations. The component is suitable for both new installations and repair work where secure, leak-free joints are required.

Advantages

This compression ring delivers consistent mechanical holding force for push-fit fittings on pipes with the specified dimensions, helping to maintain pressure integrity in potable water and central heating systems. The metal construction offers dimensional stability and resistance to deformation during assembly, reducing the risk of movement or separation under normal operating conditions. Its straightforward design allows fast installation without additional sealing materials when used with compatible push-fit connectors.

Suitable for

• Securing push-fit connectors on 18 mm pipes with 2.5 mm wall thickness
• Potable water supply lines
• Heating system pipe connections
• Repair and replacement of push-fit joints

Key specifications

• Material: metal retaining ring (compatible with standard push-fit systems)
• Intended pipe outside diameter: 18 mm
• Intended pipe wall thickness: 2.5 mm
• Function: mechanical retention for push-fit fittings, preventing axial pull-out
• Typical application temperature range: suitable for potable water and heating systems (follow system component limits)

How to use

Ensure the pipe end is clean, straight and free of burrs. Slide the compression ring onto the pipe up to the recommended insertion depth for the selected push-fit connector. Insert the pipe into the push-fit fitting until it reaches the internal stop; the compression ring will engage with the fitting and provide mechanical retention. Verify joint integrity by checking the insertion depth and performing a pressure test as required by local plumbing standards.

Usage recommendations

Use this compression ring only with compatible push-fit fittings and pipes of 18 mm outside diameter and 2.5 mm wall thickness. Do not attempt to use the ring on undersized or oversized pipe dimensions. Follow the push-fit fitting manufacturer's instructions, perform a pressure test after installation, and inspect joints periodically for signs of wear or leakage.
