Threaded Ends OG101

Rubber expansion joints are perfectly suitable to protect the pipe against thermal stress and vibrations and therefore help to avoid annoying defects or cost-intensive system shutdowns. Our rubber expansion joints from the OG series are applicable universally and absorb lateral, angular and axial vibrations. Besides our standard expansion joints with bellows made of EPDM or NBR in connection with zinc coated steel flanges or socket connection, we also offer special executions. Our PTFE or Hypalon coated expansion joints are nearly indispensable for chemical industries.
