These joints reduce stress, vibration, and noise in piping systems by providing a point of flexibility to absorb movement. 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.

Position the expansion joints as close as possible to anchor points. 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).

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.
