The GOMAX® Italy make Products have been expressly designed to substitute the rigid copper tubing when connecting discharge and suction lines, pressure switches, manometers, oil return and oil equalization lines. The use of flexible hoses, not only simplify dramatically the installation operation, but also eliminates the problems caused by the effect of vibrations that is associated with copper tubing, reducing sound levels and vibration transmission significantly and at the same time eliminating the risk of rupture and leak of refrigerant.
The assembly tooling for the QUADRA hose allows the operator to assemble the machine, or carry out maintenance and to work quickly, flexibly and securely, reducing to a minimum the need of brazing operations

The QUADRA flexible thermoplastic capillary hoses, 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 hoses, so identifying in an unambiguous way the two parts of the circuit. This reduces the possibilities of misconnections of the two pressure lines of the machine during production and maintenance. The extraordinary number of QUADRA fittings covers all possible types of installations, making the need of copper rigid tubes and capillaries unnecessary. QUADRA hoses and fittings can be easily assembled using the specific QUADRA hand pliers, or the all new QUADRA CRIMP.
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, installation and connection of QUADRA® flexible hose does not need any particular specialization and so making the connecting operation within anyone’s ability.

The test was made using a specific equipment called “Solar Box ERICHSEN mod. S1D (Xenon Lamp)”. The duration of the test has been 200 hours in total. The evaluation is based on the observation of the grey tones of the samples: the samples should not change their grey scale.
The evaluation is expressed on a scale from 1 to 5, where 1 is very bad and 5 is excellent. The orange sample achieved rating 4 (good). The black sample achieved rating 5 (excellent). Hence it follows that for all applications where the hoses are exposed to direct and frequent sunlight, black Quadra hoses are to be preferred.
