KAN-therm press-fit connector 40x20 with crimp ring PRES model 1009046047

The KAN-therm press-fit connector 40x20 with crimp ring PRES model is a plumbing fitting designed to join a 40 mm pipe to a 20 mm pipe using a pressed crimp ring system. Manufactured by KAN-therm for use in heating, potable water and sanitary installations, the connector provides a compact transition between differing pipe diameters and is intended for use with compatible press tools and KAN-therm piping systems.

Advantages

The connector offers a secure pressed joint achieved by a crimp ring that minimizes leak risk and reduces installation time compared with threaded or soldered connections. Its compact form factor allows installation in confined spaces where a reliable reduction from 40 mm to 20 mm is required. The component is compatible with standard press fittings and is designed for long-term use in typical plumbing and heating applications.

Suitable for

• Reducing pipe diameter from 40 mm to 20 mm in heating systems
• Potable water supply lines requiring a compact transition fitting
• Sanitary installations where press-fit connections are preferred
• Installations using KAN-therm compatible piping and press tools

When it may not be suitable

This press-fit connector is not suitable if the installation requires a different connection method such as threaded, soldered or welded joints. It is also unsuitable for use with pipe materials or press systems that are not compatible with KAN-therm press fittings. For high-temperature, high-pressure, or chemical environments beyond standard domestic and commercial plumbing specifications, a product selected specifically for those conditions should be used.

Key specifications

• Connection types: press-fit with crimp ring
• Pipe diameters: reduction from 40 mm to 20 mm
• Intended applications: heating, potable water, sanitary systems
• Material compatibility: designed for use with KAN-therm press-system pipes
• Installation method: requires press tool suitable for crimp rings

How to use

Prepare both pipes by cutting them square and deburring inner and outer edges to ensure a clean fit. Slide the crimp ring over the larger pipe end or position it according to the press system instructions, insert the smaller pipe into the connector until it seats fully, and actuate the compatible press tool over the ring to create a permanent crimped joint. After pressing, visually inspect the joint for correct deformation and verify system integrity according to local codes and pressure–leak testing procedures.

What to consider before purchase

• Confirm compatibility of your pipes and press tool with KAN-therm press fittings
• Verify that a 40 mm to 20 mm reduction is the required size for your system
• Check installation space to ensure accessibility for a press tool
• Ensure the fitting material and press method meet local plumbing codes and operating conditions

Usage recommendations

Use appropriate personal protective equipment when operating press tools. Follow the press tool and KAN-therm installation guides for ring placement and pressing parameters. Perform pressure testing after installation to confirm leak-free joints prior to commissioning the system.
