Expansion Joints

Expansion Joint
One-piece design for vertical pipe installations.

Fernco’s one-piece expansion joints allows thermal expansion and contraction of drain, waste and vent pipes and inside rain water conductor systems. Eliminating costly offsets normally used to accommodate expansion and contraction, this coupling is an ideal solution for vertical pipe installations.



  • Unique one-piece construction
  • Internal stops for positive positioning
  • Eliminate malfunctioning sliding parts
  • Eliminate jamming, freezing or leaking
  • Maintenance-free


  • Maximum test pressure: 4.3 PSI (29.6KPA)
  • Maximum operating temperature: 140° F nonconsistent
  • Consult pipe manufacturer for expansion and contraction information to determine the number of expansion joints needed for your specific application
