The Quadra system - comprising of thermoplastic flexible capillary hose, fittings in brass and steel and dedicated tooling - gives quick production, in a few simple steps, with superior quality connections to the pressure test points, gauges, the pressure switches including the oil return circuits and oil level equalization, for air conditioning and refrigeration units of each type and size.
The QUADRA DN2 (internal diameter 2mm), flexible thermoplastic capillary hose, represent the most efficient and developed system for the connection of pressure gauges, pressure switches and pressure test points. Transfer Oil advice the standardization of use of the QUADRA DN2 hose. The extraordinary number of QUADRA DN2 fittings covers all possible types of installations, making the need of copper rigid tubes and capillaries unnecessary. QUADRA DN2 hoses and fittings can be easily assembled using the specific QUADRA hand pliers RXA007.
