Refrigeration systems are subject to mechanical vibrations. These are caused by compressors, driving motors and gas pulsations, and are being transferred to equipment and pipe work. Small bore copper lines in the first place, as these are used for connecting auxiliary equipment such as pressure switches, are very vulnerable and taking up the vibrations, may grow brittle and the result could be a broken tube.

REFFLEX® is an extremely strong material and yet has a great vibration eliminating performance, vibrations do not come through! Apart from that, because of the simple way of making your own flexible connection, along with the wide range of special fittings, REFFLEX® is not only safe, it is cost reducing as well.

REFFLEX® is a product of The Netherlands and is applied by contractors and OEM customers all over the world. REFFLEX® is suitable for almost all non-corrosive refrigerants including natural gasses.

Refflex tubes

REFFLEX® capillary tubes and fittings

REFFLEX® offers a full choice of straight, angle and tee-connectors. The flared nuts are made of hot-forged brass as the best option for the refrigeration industry. Both straight and angle connectors have the swivel nut sliding backwards far enough to position a copper gasket whenever required.

Access valve depressors are available for the 1/4” flare fittings.


REFFLEX® simplifies the connections of

  • Pressure switches
  • Pressure transducers
  • Manometers
  • Water flow controls
  • Fan speed controls
  • Oil separators, level regulators (5.0 mm ID)

REFFLEX® tube complies to EN-1736

REFFLEX® polyamide capillary tubing

REFFLEX® is the most sophisticated system of polyamide capillary tubing, having excellent mechanical and thermal properties combined with a very high flexibility. It is suitable for all non-corrosive refrigerants including natural gases such as CO2 and propane and the relevant special oils such as ester- an PAG.

REFFLEX® refrigeration hose has the following excellent properties:

  • highly flexible, bending at extreme short radius,
  • types for HFC/HFO, HC and CO2,
  • suitable at -40°C/115°C / HP hoses: -40°C/130°C
  • max.working pressure 80 bar / HP hoses 130/160 bar
  • maximum working pressure 80 bar (contact us for higher WP),
  • very high burst proof values;
    • DN-2.0 mm > 450 bar,
    • DN-5.0 mm > 400 bar,
    • DN-5.0mm CO2 > 600bar.
  • absorbing all possible multi directional vibrations,
  • ozone-, UV-, and oil resistant,
  • fitting sizes 7/16" and 5/8" UNF (SAE 1/4" and 3/8"), 6.0 mm ODS and for 6.0 mm compressions fittings (Ermeto®, Walpro)

REFFLEX® quick easy assembly or prefabricated hoses

Sophisticated tools are available for preparing the best quality connections with REFFLEX® hoses and fittings.
The work bench tool is the ideal choice for series production, while the hand held tool does the job on site.

For the DN-5.0 mm range with crimping fittings an electrical crimping tool is available, for even faster installation.
The DN-5.0 mm screw fittings do not require special tools at all.

We also offer prefabricated hoses, ready to use.
