## Long description

Transitional coupling SANHA-Therm ZWxGW 18x3/4 by SANHA is designed to join 18 mm copper or plastic tubing with 3/4" threaded fittings. The coupling provides a mechanical transition between metric tube and imperial threaded components, creating a sealed connection suitable for heating, plumbing and sanitary systems. Constructed to match typical installation practices, the coupling is intended for reliable through-wall or in-line connections where a change of connection standard is required.
Advantages
The transitional coupling offers a compact design that simplifies connection between 18 mm tubing and 3/4" threaded parts without the need for adapters that alter flow or increase leak points. Its construction enables consistent sealing and mechanical stability under normal domestic and light commercial operating conditions. The product supports quick installation workflows and reduces the number of separate fittings required in mixed-standard systems.
Suitable for
Connecting 18 mm copper or plastic tubes to 3/4" threaded valves and fixtures
Heating system pipelines where metric-to-imperial transitions are needed
Plumbing repairs and retrofits that involve mixed standard components
Sanitary installations requiring a sealed mechanical transition
Key specifications
Tubing connection size: 18 mm designed for copper or compatible plastic tubes
Threaded connection size: 3/4" compatible with standard 3/4" female or male fittings
Function: transitional mechanical coupling between metric tubing and imperial threaded components
Application areas: heating, plumbing and sanitary installations
How to use
Prepare the 18 mm tube by cutting squarely and deburring the end. Insert the tube into the coupling up to the designed stop and secure according to the manufacturer's recommended assembly method for the SANHA-Therm system. Thread the 3/4" side into the corresponding threaded fitting, ensuring appropriate sealing (for example, thread sealant or tape where required by the installation practice). Verify alignment and tighten to the torque appropriate for the connected materials and fitting type. Perform a pressure test of the system after installation to confirm a leak-free connection.
Usage recommendations
Use the coupling only with compatible 18 mm copper or approved plastic tubes and standard 3/4" threaded fittings. Follow local codes and the SANHA installation instructions for pressure limits, temperature ranges and correct sealing methods. Inspect joints after thermal cycling and perform periodic checks as part of routine system maintenance.
