O-ringuri - Etanșări
Orings are universal sealing elements used to seal against liquid or gaseous median. They are suitable for static and minor dynamic applications. Orings can be used for radial and axial sealing. The sealing occurs during installation by the radial or axial compression of the crosssection. During operation, the median pressure increases the deformation of the Oring and so increases the sealing effectiveness. For best sealing effectiveness, the Oring should have the largest possible crosssection.
During installation the correct groove size, compaction, elongation/compression should be ensured.
By static use the compaction should be 15 30% of the crosssection. By dynamic use it should be 10 18% (hydraulic), 4 12% (pneumatic).
With regard to the ID, when installed the Oring should be
stretched max 6%
compressed max 3%
