TOP HYDRAULIC AND PNEUMATIC SEALS

CUSTOM-MADE ON A SEAL MASTER MACHINE IN 24 HOURS

O-rings are sealing elements with extremely precise dimensions. They are produced by molding in tools and are primarily used for static applications or in conditions of occasional movement. The shape, material, hardness, sizes, and tolerances comply with the DIN 3770 standard, which corresponds to the DIN-ISO 3601 standard.

O-rings have a very demanding function. Their tasks range from vacuum sealing to resistance against heat, oil, greases, acids, bases, and other aggressive media. O-rings are the most commonly used type of seal in various branches of industry. Precision O-rings are a specific type of sealing element used in systems where high sealing reliability and precise dimensional adaptation are required.

Characteristics of Precision O-Rings according to DIN standard 3771:

  • High dimensional accuracy: Precision O-rings are made with special attention to dimensions to ensure accurate and reliable sealing. This is particularly important in applications requiring precise fitting and minimal tolerances.
  • High quality materials: These O-rings are made from high-quality materials such as nitrile, EPDM, FKM, or other elastomers that are resistant to wear, chemically aggressive media, and high temperatures.
  • Wide range of sizes: Precision O-rings are available in various sizes, diameters, and thicknesses to meet different application needs.
  • Low degree of deformation under compression: Our O-rings exhibit low compression deformation, meaning they retain their shape and elasticity over time and under varying operating conditions.
