Toroidal seal POR

NBREPDMfor hydraulic fluids

Hunger precision O-Rings and toroidal sealing rings are used as static seals. By selecting suitable materials, a wide range of sealing problems involving different fluids, pressures and temperatures can be solved. The sealing effect is based on the principle that the installation space in one direction is smaller than the profile diameter. As a result of the elasticity of the material, the ring deforms and provides an adequate seal, even in the pressureless state. The onset of pressure increases the deformation and thus the sealing effect. It is important to keep the gap behind the ring - as seen in the pressure direction - as small as possible so that the sealing material cannot flow into the gap. This would cause the destruction of the seal. It is also important to select the correct shore hardness which should be correspondingly higher at higher pressures.
