The QUADRA DN6 are characterized by an internal diameter of 6 mm, and therefore they can substitute copper rigid tubing of OD 8 mm or 5/16”. The larger internal diameter reduces the pressure drop and makes the use of this hose possible on larger systems for the oil return lines and for the oil equalization systems. The crimping fittings for the QUADRA DN6 hose are available with connections of 1/4” SAE and 3/8” SAE and can be connected to the hose using the same hydraulic pliers RXA005 as used with the QUADRA DN4 hose. For large scale production it is now possible to use the new electric plier RXA010 which easily crimps the fittings for QUADRA DN2, DN4 e DN6 hoses.

The permeability value provides an indication of the maximum leakage tested at constant conditions of use. Permeability is measured in grams, permeated from a square meter of the internal surface of the hose during one year (g/m2 per year). The real permeability value must therefore be measured considering the actual working time and temperatures to which the hose is subjected. Download Inner tube Thermoplastic polymer reinforcement Polyester braid of high tensile strength with high modulus Cover Thermoplastic polymer – orange or black – white ink-jet branding on black hose, black ink-jet printing on orange hose Applications Connection of pressure gauges, pressure switches and pressure test points features Light – Flexible – Compact – Vibration absorber Temperature range ↑ to top -45 °C to +130 °C (-49 °F to +266 °F) UV resistence 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. Description 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.
