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.

Polyamide capillary hose

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® hose has the following excellent properties:

  • highly flexible, bending at extreme short radius
  • absorbing all possible multi directional vibrations


Various fittings

REFFLEX® offers a full range of straight-, angle - and T-connectors. The flared nuts for both DN-2.0 and DN-5.0 fittings are made of hot-forged brass, as is 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 with all 1/4" flare fittings.
