Rubber Expansion Joint Water Transmission - High Pressure Line

Thermal growth, equipment movement, vibration or pressure pulsation may generate movement in a rubber joint piping system. When this movement is not absorbed by the piping system itself, an expansion joint is the perfect solution. A Rubber Expansion Joint is flexible connector fabricated of natural or synthetic elastomers, fluoroplastics and fabrics and, if necessary, metallic reinforcements used to absorb movements in a rubber joint piping system while containing pressure and a medium running through it.

Rubber Expansion Joints are manufactured considering

  • Chemical and Temperature resistance of internal layers
  • Pressure-resistant reinforcing fabrics
  • Weather, ozone and UV-resistance of external layers

There are four basic movements that can be absorbed by a rubber Expansion Joint


  • Minimal face-to-face dimensions while absorbing large movements
  • Low Spring Rates due to inherent flexibility of rubber
  • Corrosion and Erosion resistance
  • No gaskets required for installation
  • Reduced fatigue factor
