Benefits of our Sealings

  • highest sealing function
  • pure graphit or silicone procure permanent elasticity (no embrittlement by oxygen or high temperatures)
  • heavy duty by sealing function in force shunt
  • blow-out proof by chambered sealing rings in nuts
  • easy to assemble, without maintenance, because no tighten up of screws necessary
  • highest stiffness in flange connection, screws and bolts prestressed perfectly
  • highest insulating function, up to 5 (7) kV alternating voltage - no electrical breakdown
  • functionally reliable for life by insubstantial water absorption
