Expansion Joints with Flanged Ends
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.

Expansion Joints with Sealing Flanged Ends for Plastic Pipe
- For Use With: Alcohol, Water
- Temperature Range: -20° to 250° F
- Maximum Pressure: 220 psi @ 72° F
- Maximum Vacuum: 24 in. of Hg @ 72° F
These joints reduce stress, vibration, and noise in plastic piping systems by providing a point of flexibility to absorb movement. Joints provide a tighter seal than other expansion joints because the flanges are molded into the body for a wide sealing surface. 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.
