TWINFLEX S

Feature

  • High Efficiency for Vibration and Noise Isolation
    The twin sphere makes the spring constant small, decreases the body natural frequency and increases the
    efficiency of vibration absorption.
  • Withstandability
    It can withstand a bursting pressure of over 5.0MPa and a maximum working pressure of 1.6MPa and with
    the combination of excellent formative technique and strong chemical fibre.
  • Large Displacement Absorption for Eccentricity, Axial Movement and Angular Movement
    Since it can absorb large displacement, TWINFLEX screwed type flexible rubber joint is most appropriate
    for the protection of pipe line system. For example, it can prevent the destruction of connecting pipe
    due to earthquake and subsidence of ground.
