    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

    These expansion joints have a double-bulb design for extra movement and vibration absorption. The flanged ends rotate for easy bolt hole alignment during installation. They mate with a same-size flat-surface Class 150 flange without the need for a gasket. Joints have a flexible body that is reinforced with nylon for added strength.

    Limit Rod

    Limit Rod Sets—Attach limit rod sets (sold separately) to the flanges to prevent overextension where anchoring is insufficient. To accommodate the thickness of the limit rod mounting plate, use bolts that are 7/8" longer than the bolts connecting the expansion joint to the pipe flange. Each set of limit rods requires eight bolts (not included).

    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.

    To attach joints, connect to unthreaded male socket-connect fittings or pipe using a PVC primer and cement (also known as solvent weld).
