Special designs

Certain specialised areas of various industries require at times applications which cannot be adequately realised by the use of standard components.

Specially designed expansion joints are used in these cases. The following specific design types are offered in addition to the standard series:

  • pressure balanced expansion joints for axial and lateral movement
  • elbow-conected pressure balanced expansion joints
  • chamber expansion joints
  • expansion joints, pressure applied externally
  • expansion joints with PTFE
  • single used expansion joints
  • expansion joints for food industrie
