Fittings are available in the following sizes:
tube from 4 up to 14;
thread of M5 to 1/2.

The 55000 series has been produced using innovative material such as last generation technopolymeric.
Thanks to the use of these new materials, we've been able to realise very light and safety fittings.
The use of thechnopolymeric fittings ensures to avoid dangerous eletrical phenomena and in case of overpressure there won't be any formation of splints. This is thanks to the materials features, they are ductile and not conductive.

 

The collet is made in stainless steel ensure the perfect tube clamping with every kinds of materials without damage the surface.
The connection between the tube and the fittings ensure a total tightness even in severe conditions such as impact and vibrations.
The particular geometric shape of the seal ensure the perfect tightness even with vacuum.


The "short" taper thread has been designed to offer the following advantages to the users:

  • reduced overall lenght;
  • smaller hex dimensions compared to the parallel threads;
  • to allow the assembly with different female threads both taper as well as parallel;
  • to ensure the right tightening also with surfaces not perfectly flat, without spot-facing, concave convex and with different kinds of chamfers or radius.
 

Torque specifications
Minimum torque: 5 Nm             Maximum torque: 7 Nm

All of threads from this range (also the M5), have been equipped with tightening parts which allow the direct assembly of the fittings, reducing the installation time.

All the straight fittings, with "short" and parallel threads can be assembled also with Allen wrench and it is possible to use them in reduced spaces.
