## Summary description

KAN-therm compression coupling for piping systems, size 25x2.5 mm, equipped with an external G¾" thread (model K-900003). Designed to connect pipes with a 25 mm outer diameter and 2.5 mm wall thickness, providing a threaded outlet for fittings or valves. Suitable for use in central heating, potable water and plumbing installations where a G¾" threaded connection is required.

## Long description

KAN-therm compression coupling 25x2.5 with external G¾" thread (model K-900003) is a mechanical connector designed to join two pipes with a 25 mm outer diameter and 2.5 mm wall thickness while providing a G¾" threaded outlet for attaching valves, fittings or instruments. The coupling is intended for use in central heating, potable water and general plumbing systems where a secure compression joint and a standardized threaded connection are required. The design accommodates polymer or multilayer pipes compatible with KAN-therm compression fittings and ensures a compact threaded take-off point without the need for additional adapters.
Advantages
The coupling provides a reliable compression seal without soldering or welding, allowing quick assembly and serviceable joints. The integrated external G¾" thread simplifies installation of faucets, drains, drain valves or pressure instruments directly onto the pipe run. Its compact form factor minimizes space requirements in concealed installations, and the mechanical design enables disassembly and re-tightening for maintenance. Materials and construction meet typical requirements for potable water and heating applications.
Suitable for
 Connecting 25x2.5 mm pipes in residential and commercial central heating systems
 Providing a G¾" threaded outlet for fixtures and valves in potable water installations
 Plumbing applications requiring a reliable compression joint and a threaded take-off
 Retrofitting or extending existing pipe runs where a threaded connection point is needed
Key specifications
 Pipe outer diameter: 25 mm
 Pipe wall thickness: 2.5 mm
 Thread type: external G¾"
 Connection method: compression fitting
 Typical application: central heating, potable water, general plumbing
 Compact mechanical design suitable for concealed and exposed installations
How to use
Prepare pipe ends by cutting square and deburring inner and outer edges. Slide the compression nut and compression ring onto the pipe, insert the pipe fully into the coupling body, and tighten the nut to the specified torque to achieve the compression seal. Attach the required fitting or valve to the external G¾" thread, applying appropriate thread sealant or tape if required by system practice. Follow system pressure testing procedures after assembly and check for leaks. For maintenance, the compression nut may be loosened and re-tightened or replaced as needed.
Usage recommendations
Use this compression coupling only with pipes and fittings compatible with KAN-therm compression systems and within the pressure and temperature limits of the installation. Ensure correct tightening torque to avoid under- or over-compression. Observe local plumbing codes and manufacturer guidance for potable water and heating system installations.
