KAN-therm łącznik redukcyjny press 40x3,5/25x2,5 pipe fitting, model 1009046052

KAN-therm łącznik redukcyjny press 40x3,5/25x2,5 pipe fitting (model 1009046052) is a reduction coupling for press-fit connections that allows a secure transition between 40 mm (3.5 mm wall) and 25 mm (2.5 mm wall) plastic pipes. Designed for use in heating, potable water and general plumbing systems, this press fitting creates a mechanically crimped joint that reduces assembly time compared with traditional soldered or threaded connections. Installation requires compatible press tools and jaws intended for KAN-therm press fittings.

Advantages

The press reduction fitting provides a reliable, leak-resistant connection when installed with appropriate press tooling. Its design matches the dimensional requirements of the specified pipe diameters and wall thicknesses to ensure a consistent fit and pressure integrity. Using a press connection reduces installation time and eliminates the need for open flame or adhesives, which can improve safety on site. The fitting is suitable for repeated handling during assembly and is compatible with standard press installation workflows.

Suitable for

• Transitions between 40 mm (3.5 mm wall) and 25 mm (2.5 mm wall) plastic pipes
• Domestic and light commercial heating systems
• Potable water distribution lines where press fittings are permitted
• Plumbing installations requiring a compact reduction joint

When it may not be suitable

This press reduction fitting is not suitable for pipe systems with different material specifications, diameters, or wall thicknesses than those stated (40 mm with 3.5 mm wall and 25 mm with 2.5 mm wall). It should not be used where connection methods other than press joints are required by code or project specifications. For systems exposed to chemicals or operating conditions outside the manufacturer’s stated limits, alternative materials or fittings should be selected.

Key specifications

• Connection type: press-fit reduction coupling
• Inlet diameter: 40 mm, wall thickness 3.5 mm
• Outlet diameter: 25 mm, wall thickness 2.5 mm
• Application: heating, potable water, general plumbing
• Joint type: mechanically crimped (press) for leak-resistant seal

How to use

Prepare the pipes by cutting squarely, deburring and cleaning the pipe ends to ensure full insertion into the fitting. Slide the KAN-therm press fitting onto the larger and smaller pipe ends to the required stop depth. Select the correct press jaw for the fitting profile and pipe diameter, and position the tool so the pressing marks align with the tool jaw. Perform the press operation according to the press tool manufacturer’s instructions. After crimping, inspect the joint visually and, where applicable, pressure-test the system following project requirements and local regulations.

What to consider before purchase

• Confirm compatibility with the pipe material and the specified diameters and wall thicknesses (40x3.5 and 25x2.5 mm)
• Ensure availability of compatible press tools and jaws for KAN-therm press fittings
• Verify that press connections are allowed by local codes for the intended application (potable water, heating)
• Check maximum operating pressures and temperatures in system design to match fitting capabilities

Usage recommendations

Use only certified press tools and correct jaw profiles for KAN-therm fittings, follow manufacturer instructions for pressing and testing, and perform a pressure test after installation to confirm joint integrity before putting the system into regular operation.
