The assembly of the O-Rings

The efficiency and the duration of the O-Rings' seal are connected to the preservation of the chemical and physical characteristics. An incorrect job or an incorrect assembly, such an example could provoke superficial scratching to the ring, could be the cause of decay of the capacity of the seal and of the accelerated ageing of the compound.

The assembly phase subject the O-Ring to physical stress which can compromise the integrity, it is advised therefore to observe some rules to avoid the compromise of the seal capacity with an inaccurate assembly. The replacement of an O-Ring involves stopping the system and, sometimes complex, maintenance actions that must be planned to reduce the economic impact. The reduction of the effect duration of the ring seal due to an incorrect assembly, involves an increase in system running costs.

In this charter we show which are the most frequent risks and how to avoid damage to the rings.
