KAN-therm reducing coupling 22x15 mm steel 620112.9

The KAN-therm reducing coupling 22x15 mm steel 620112.9 is a mechanical pipe fitting designed to join pipes of different diameters, providing a transition from 22 mm to 15 mm. Constructed from steel, the coupling offers mechanical strength and resistance to deformation under pressure, making it suitable for plumbing and heating systems where a compact, reliable reduction is required.

Advantages

The steel construction ensures durability and improved mechanical resistance compared with some non-metal alternatives. The compact design enables installation in confined spaces and allows a secure transition between 22 mm and 15 mm pipework. Designed for compatibility with PEX and various metal pipes, the coupling provides stable connections and consistent flow characteristics when used according to standard installation practice.

Suitable for

• Domestic and commercial plumbing systems requiring a diameter reduction from 22 mm to 15 mm
• Underfloor heating and radiator connections where size transition is necessary
• Repair and retrofit jobs involving PEX or metal pipework
• Applications requiring a compact mechanical coupling with steel strength

Key specifications

• Material: steel for the coupling body
• Connection sizes: reduction from 22 mm to 15 mm
• Compatible pipe types: PEX and common metal plumbing pipes
• Design: mechanical reducing coupling for inline installation

How to use

Select appropriate pipe ends and prepare them according to the pipe manufacturer’s instructions, ensuring clean, deburred and correctly cut surfaces. Fit the coupling onto the 22 mm pipe end and then insert the 15 mm pipe into the opposite side until fully seated. Secure the connection using the compatible method specified for the coupling type and the pipe material—this may include crimping, pressing or threaded connection if applicable. Verify alignment and ensure that the joint is tight and leak-free before placing the system into service. Follow applicable plumbing and heating codes during installation.

Usage recommendations

Use the coupling within the temperature and pressure limits recommended for the piping system materials. Where dissimilar metals are joined, consider appropriate corrosion protection or dielectric isolation. Inspect joints after installation and perform pressure tests according to standards to confirm leak-tight performance.
