    Customized barrel stock matching

    We customize the blanks based on the required seal ring dimensions (e.g., barrel stock with inner and outer diameters close to the finished product dimensions). This reduces turning effort, improves material utilization, and reduces raw material costs.

Why choose a large seal

Large seals are subject to extremely demanding requirements. As the size of machinery increases, not only do material and energy costs rise, but so does the need for seals that withstand extreme conditions. Especially for demanding applications, special high-performance plastics with increased wear resistance are required.


For example, large seals are used in the following applications:

  • Power plants/hydropower/turbines

  • Mining and tunnel construction

  • Large hydraulic presses

  • Pipelines

  • Shipping
