  • connection ducts having a bellows-like structure provide the desired flexibility and leak-proofing, after some period of time they tend to become deformed under the working conditions and are torn or punctured becoming unable to function.
  • o-rings are assembled between the connection ducts that move relative to each other to provide flexibility and leak-proofing, however, the o-rings are insufficient in attenuating the vibrations in this type of connections and are worn away in the course of time due to friction.
