    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.

    Pipe Expansion Joints with Threaded Ends

    Connect male threaded pipe to these expansion joints to add a point of flexibility in your line that reduces stress, vibration, and noise. These joints have a double-bulb design that absorbs more movement and vibration than other expansion joints. Made of neoprene, they’re more abrasion resistant than silicone rubber joints. Their flexible body is reinforced with nylon for added strength.

    Shown Installed on a Flanged Pipe

    Connect different pipe sizes in your line while adding a point of flexibility between them. These expansion joints absorb movement between two connected pipes to reduce stress, vibration, and noise. Their flanged ends mate with same-size Class 150 flanges without the need for a gasket. Each flange is supported by a zinc-plated steel plate. The body of these expansion joints is reinforced with cord for added strength.
    Your pipe system must be rigidly anchored on both sides of the expansion joint to control expansion or contraction of the line. When proper anchoring cannot be provided, limit rods (sold separately) are required.

    Pipe Expansion Joints with Socket Connection for Plastic Pipe

    Reduce stress, vibration, and noise in your plastic socket-connect piping system by creating a point of flexibility. These expansion joints have a double-bulb design, so they absorb even more movement and vibration than other expansion joints. Their body is EPDM that's reinforced with nylon for added strength.
    Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
