Sealing elements

This group includes a wide range of various types of shaped sealing elements used in numerous fields. The main types of sealing elements are, for example, O-rings, X-rings, sleeves, scraper rings, shaft sealing rings, V-rings.

Overview of sealing elements

  • O-rings

An O-ring is a rubber sealing element used for the prevention of undesired leakage or loss of a liquid or gas. It may be used for dynamic as well as static sealing.

  • X-rings

Their main advantage in comparison with common O-rings is their possible use in rotary sealing, higher stability in a filled space, lower radial prestressing in the groove and thus lower friction and wear.

  • Sleeves

Sleeves are among the most important sealing elements of the moving parts of hydraulic and pneumatic devices with straight sliding motion.

  • Scraper rings

Scraper rings serve to scrape impurities from the piston surface, protecting themselves, the medium and the cylinder from damage.

  • Compound piston seal KO3

A five-piece compound seal used for hydraulic systems, with easy assembly on a single-piece (non-segmented) piston.

  • Shaft sealing rings

Shaft sealing rings (HTK) serve to seal moving parts of machinery components and units filled with oil, grease, and other liquids.

  • V-rings

All-rubber axial pressureless sealing elements of rotary shafts and bearings. Wide range of use in mechanical engineering, water treatment devices, rolling mills, etc.

  • Circular profiles

Rubber circular profiles serve mostly in the production of sealing O-rings by gluing, and for sealing lids, flanges, etc.

  • Silicone square profiles

Manufactured with the same technology as silicone tubes, used in special applications where circular profiles or tubes may not be used.

  • Rubber films

A starting material for cutting or clipping various shaped sealing elements, pads, and special parts. May also be used as insulation.
