Statotherm V Cover seal V881-… For a larger view, please mouseover the image.
Statotherm V Cover seals V881 are made from pure graphite (purity > 99%) with internal stainless steel inserts for seal spaces with larger gaps and/or higher pressures e.g. for power plants at high temperatures and up to approximately 1,000 mm diameter.
  • Suitable for sealing of larger gaps
  • Easy installation and removal
  • No damaging of the seal surfaces
  • Very good extrusion properties
  • Ensures operating safety
  • No hardening
  • Long service life
