The QUADRA DN2 (internal diameter 2mm), flexible thermoplastic capillary hose, in orange colour represents the most efficient and developed system for the connection of pressure gauges, pressure switches and pressure test points.

Flexible thermoplastic capillary hose dedicated to the connection of pressure gauges, pressure switches and pressure test points in Air Conditioning and refrigeration systems. In contrast to the brazing or bending operations that are necessary for rigid copper tubing, the installation and connection of QUADRA® flexible hose does not need any particular specialization and so making the connecting operation within anyone’s ability.
