O - R I N G S

Used for the tightness of two elements without moving (static tightness) or two parts on moving (dynamic tightness).

We have available the most extense range of measures, from 1 to 1.000 mm. of inner diameter.

Static tightness :  The o-rings are able to resist up to 1.000 bar with an adecuate material.

Dynamic tightness : It must be distinguished between two systems: HIDRAULIC and PNEUMATIC.

In dynamic tightness of HIDRAULIC SYSTEMS, compression and deformation of the o-ring make this was able to adapt on the surface.

In dynamic tightness of PNEUMATIC EQUIPMENTS, it is recommended to reduce the friction of the o-ring in its axial displacements because of the lack of lubrication.

For this reason the o-rings deformation will be maintained in a maximum level of 6% and a minimum one of 2%.

O-rings must be combined some specific conditions for their running:

* Resistance to environment (oils, steam, chemical products, etc.)

 

* Resistance to operation temperatures.

* Resistance to permanent deformation.

* Resistance to wear and tear.

* Elasticity.

* Operation pressure.

On the points above mentioned, it will be depend on the election of the appropiate material for the o-ring (nitrile, silicone, viton...). Our technical department will advice you the adecuate o-ring according your necessities.
