Radial seals - Import export

XXL O‑rings are typically used as static radial or static axial seals in mechanical, power plant, plant and heavy equipment engineering. The special stagevulcanization production technology is also suitable for single or small lot production of smaller O‑rings with a nonstandard inside diameter.

The X‑ring is a continuous, seamless vulcanized ring with a special profile which is derived from four O‑rings arranged in a square crosssection.The particular advantage of the X‑ring is that it cannot roll or twist. The squeeze required to maintain an effective seal is also relatively low.The X‑ring is used in mechanical and automotive engineering, preferably as a static radial or static axial seal. Other applications are for linear or rotary motion of plungers, pistons, tappets, dampers and valve, bearing and piston rods, etc.

The POLYPAC® - Balsele is a compact rod seal consisting of an elastomeric sealing element and an integrated fabric reinforced base. Due to the radial pre-load an excellent sealing performance will be achieved even at low pressures. The fabric reinforced base prevents the seal from extrusion.
