Pipe Expansion Joint Reducers with Flanged Ends
 |  |
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.
