Special seals

Special seals

Special seals are designed for demanding applications where standard sealing elements are insufficient. We offer:

  • Sealing rings for high-pressure washers – resistant to pressurized water and fluctuating temperatures. Made from abrasion-resistant materials to ensure long service life and tightness in cleaning systems.

  • Rotary seals for excavator slewing columns – used in the rotating joints of construction equipment. These seals prevent hydraulic oil leakage and protect against ingress of dirt and moisture.

  • Custom seals – manufactured according to customer specifications, including non-standard shapes, materials, or operating conditions (e.g., high pressure, unusual media, extreme temperatures).

Thanks to advanced materials and precision engineering, our special seals provide durability and performance even in the harshest operating environments.
