    Because the flanges are molded into the body for a wide sealing surface, these joints provide a tighter seal than other expansion joints. Each flange is supported by a zinc-plated steel plate. Flanges mate with a same-size flat-surface Class 150 flange without the need for a gasket. Joints reduce stress, vibration, and noise in metal piping systems by providing a point of flexibility to absorb movement. They have a flexible body that is reinforced with cord for added strength.
    Mount these expansion joints as close as possible to anchor points.

    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).

    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.
