Design notes

Please observe our general design notes in → Technical Manual.

Gap dimensionThe decisive factor for the function of the seal is the largest gap dimension occurring during operation on the non-pressurised side of the seal → Technical Manual. The permissible value is determine by the pressure as well as the profile width and profile height.

Fitting & installation

When fitting the Omegat OMS-S the elastomer profile ring is first placed in the hous-ing groove, then the profile ring is deformed to a kidney shape and sprung into place.During this process it is to be ensured no sharp kinks are produced in the PTFE profile ring and that the sealing edge is correctly arranged in relation to the direction of the pressure. The entire fitting operation is only allowed to be performed over rounded edges.

The catalog details are based on the experience of many years of research in the development and production of seals in the Freudenberg Group and correspond to our current level of know-how.The sealing action of many catalog products is, however, not only created by the component itself. In many cases – depending on the specifi c application – it depends signifi cantly on the other parameters, such as installa-tion point, counter surface, pressure, operating temperature, media to be sealed, lubrication, effects of vibration and any ingress of dirt from outside. These and other unknown factors in

practical use may noticeably infl uence the functioning of the seals. Against this background generalised statements on the function of the catalog products are not possible. Details in this catalog merely represent general and non-bin-ding reference values which make no claim to be valid for every application. We therefore recommend you to always discuss specifi c applications with our consultancy service. In the event of very high and special loads, for example due to aggressive media, the seal should be selected in co-operation with us; trials to check the functional reliability are often indispensable.
