Standard-type / Rubber Expansion Joints


As a standard-type cross-sectional structure, RFF, SFL, and SFF types are available.

We propose an optimal cross-sectional structure based on client needs. (e.g. diameter, flange standards, design pressure)


  • Excellent flexibility and resilience, as the main material is rubber.
  • Durable structure strengthened with reinforcement rings and material inside the rubber.
  • Rubber packing is not required between it and the opposing flange as the contact surface is rubber. (Rubber flange structure).
  • The material of the inner surface rubber of the expansion joint can be selected according to the fluid flowing inside allowing for usage in a wide range of applications.
  • The interplanar distance can be tailored to meet client needs as the expansion joint is made-to-order.
