Assembly instructions for reusable fittings

1

step 1

Cut QUADRA DN4 capillary hose to the required length using our cutter for capillary hoses type WXA004.
2

step 2

Push the ferrule over the hose end you want to assemble. To make the operation easier we advise that you lubricate the components with refrigeration oil.
3

step 3

Screw counter clockwise, by hand, the first turns of the thread of the ferrule. A suitable wrench screw counter clockwise until the ferrule is in line with the hose.
4

step 4

Place the insert into the hose end you want to assemble. To make the operation easier we advise that you lubricate the components with refrigeration oil.
5

step 5

Screw clockwise, by hand, the first turns of the thread of the insert into the ferrule previously fitted on the hose. Screw clockwise the fitting into the ferrule until they are in line with each other by using a wrench and a counter wrench.
6

step 6

After checking the correct positioning of the components, the assembling is finished.

Assembling instructions for crimping fittings for QUADRA DN4 capillary hose

1

step 1

Cut the QUADRA capillary hose to the required lenght using the special WXA004 cutter
2

step 2

Slip the nut over the hose (depending on ftting type). Ensure that the threaded side is pointing towards the end of the hose that needs assembling.
3

step 3

When pushing the ferrule over the hose end, ensure its correct positioning, in line with the hose end. Push the insert into the hose end you want to assemble.
4

step 4

Pay attention not to move the components already fItted and slide the ferrule over the hose towards the insert positioning it in line with the insert.
5

step 5

Crimp the ferrule with our hand pliers type RXA007, up to the limit stop of the pliers: once the optimal deformation has been achieved the pliers will open automatically.
5a

step 5

Crimp the ferrule using our pliers cod.RXA005: open the punches using the special lever, then put the ferrule properly between the pinches. The deformation is achieved when the pliers release and the lever idles.
6

step 6

The assembling is fnished and the eventual nut can easily slide over the ferrule: check the correct positioning of thecomponents and make sure the entire surface of theferrule has been swaged.
Attention
Note!
Once the hose assembly is connected to the machine, do not move or rotate it, otherwise you risk loosening the nut or damaging the fitting by compromising its tightness. In case you have to modify the orientation of the coupling, unscrew the nut, position the hose assembly, then tighten the nut again respecting the torque value of 16 ÷ 18 N·m max 20 N·m.
Note!
Once the hose assembly is connected to the machine, do not move or rotate it, otherwise you risk loosening the nut or damaging the fitting by compromising its tightness. In case you have to modify the orientation of the coupling, unscrew the nut, position the hose assembly, then tighten the nut again.
Respect the nut torque value:
  • Torque wrench 14 7/16”-20 UNF for 1/4” SAE connections | 16 ÷ 18 N·m. Do not exceed 20 N·m
  • Torque wrench 22 5/8”-18 UNF for 3/8” SAE connections | 30 ÷ 32 N·m. Do not exceed 34 N·m

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

-45 °C to +130 °C (-49 °F to +266 °F)

DESCRIPTION

The QUADRA DN4 flexible thermoplastic capillary hose, in two colors orange and black, are the ideal solution for equalizing and oil return lines. The QUADRA DN4 hoses have an internal diameter of 4 mm and therefore they can substitute copper rigid tubing of OD 6 mm or 1/4”. The QUADRA DN4 hoses can be easily assembled with suitable fittings and crimped using the specific hydraulic crimper RXA005, or the all new ELECTRIC PLIER RXA010, otherwise a possible alternative is to use special reusable fittings where there are installations where special crimping tools are not available. The QUADRA DN4 hose can also be used, at the choice of the user, also for connection to the pressure gauges, pressure switches and test points as with QUADRA DN2.

Flexible thermoplastic capillary hose are 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.

 

PERMEABILITY

The specification EN 1736:2008, among other various aspects, regulates the requirements to qualify the permeability rate of non-metallic tubes used in air conditioning and refrigerating systems, including heat pumps.
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.

 

UV RESISTANCE

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.
