Encapsulated Orings Rings are mostly employed in sealing static machine parts against products in liquid or gaseous form. Under certain preconditions it is also possible to use them as dynamic sealing elements in axial, rotary and oscillating movements.
As the rings are subjected to higher temperatures and pressures, extrusion can be constant, causing excessive product deformation. Such situations require the use of special seals that resist high temperatures and higher pressures due to the types of materials used in their manufacture.
