    About Pipe Expansion Joints
    industrial info icon

    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.
