Rubber Hose Type expansion joints

These expansion joints allow for reduced vibration in fluid, slurry, and/or gas transportation or piping systems under pressure or vacuum at varying temperatures.

Product Description

Features:
  • Transportation or piping systems that carry fluids, slurries or gasses under pressure or vacuum at varying temperatures.
  • Reduction of vibration
  • Dampen sound transmission
Advantages:
  • Easy installation
  • Flanges are not in contact with medium, which enables lower grade material
  • Galvanic surfaces/ coatings possible
  • Gaskets can be eliminated
  • Manual production
  • Special measures (length, diameter, flanges) → custom made
