Key specifications
 Material: Copper
 Nominal diameter: 28 mm
 Connection type: Coupling for straight joining of tubes
 Suitable media: Water, heating fluids, refrigerants where copper is permitted
 Compatibility: 28 mm soft and hard copper tubing
 Installation methods: Soldering or other approved professional assembly techniques
How to use
Prepare the ends of the copper tubes by cutting square and deburring inner and outer edges. Fit the coupling onto one tube, align the second tube and verify proper insertion depth. Complete the joint according to the chosen approved method: flux and solder for capillary soldering, or the relevant mechanical or brazing procedure specified for the installation. After joining, allow the joint to cool and, where applicable, remove excess flux and test the line for leaks following local codes and standards.
Usage recommendations
Use the coupling in accordance with local plumbing and HVAC regulations. Ensure compatibility of fluids and operating temperatures with copper. For potable water installations follow accepted soldering practices and clean flux residues after soldering. For refrigeration systems, follow refrigerant-service guidelines and brazing procedures recommended for copper tubing.
