## Long description

Compression reducing coupling Comap 40x3.5–26x3 \| copper pipe fitting is a press-fit plumbing component designed to join copper pipes of different outer diameters. The fitting provides a mechanically secure, permanent connection between a 40 x 3.5 mm pipe and a 26 x 3 mm pipe, intended for use in heating, potable water and sanitary installations where a reliable, leak-resistant transition is required.
Advantages
The coupling offers a compact design that minimizes space requirements while ensuring a stable transition between two pipe sizes. Manufactured for press-fit installation, it provides consistent mechanical strength and reduces the need for soldering or threaded connections. The material and construction ensure corrosion resistance and long-term dimensional stability in typical building plumbing environments.
Suitable for
 Connecting copper heating pipes with different diameters
 Transitions in potable water distribution systems
 Sanitary and bathroom plumbing where a permanent press connection is preferred
Key specifications
 Material: copper-compatible press-fit fitting
 Connection types: compression/press-fit for copper pipes
 Pipe sizes: connects 40 x 3.5 mm to 26 x 3 mm outer diameters
 Application: heating, potable water and sanitary systems
 Installation: permanent mechanical press connection
How to use
Prepare the copper pipes by cutting them square, deburring the inner and outer edges, and cleaning the surface to ensure a proper press fit. Insert each pipe end into the corresponding side of the coupling until it reaches the stop. Use an appropriate press tool and compatible jaw to perform the press operation according to the tool manufacturer's instructions and accepted plumbing practice. After pressing, inspect the joint visually and, where required, perform a pressure test to confirm leak-tightness before commissioning the system.
Usage recommendations
Ensure compatibility between the press tool and the coupling profile, and use only suitable jaws designed for copper press fittings. Verify pipe dimensions (outer diameter and wall thickness) before installation and follow local installation codes and standards for potable water and heating systems.
