About Pipe Expansion Joints

Select the right expansion joint by measuring the size of your pipes and comparing types of joint movement.

Chemical-Resistant Pipe Expansion Joints with Flanged Ends

The PTFE body on these expansion joints has a super-smooth surface that stands up to corrosive chemicals. Joints have a triple-bulb design that provides excellent vibration absorption, reducing stress on your piping system. The flanges mate with a same-size flat-surface Class 150 flange without the need for a gasket. Limit rods are attached to the flanges to prevent overextension.

Clamp-On Pipe Expansion Joints

Slip these joints over your pipe ends and tighten the band clamps for a secure hold. Joints have a triple-bulb design that provides excellent vibration absorption to reduce stress on your piping system. They also have reinforcing rings for extra support during pressure surges and in vacuum applications.
