Square & Rectangular Rubber expansion joints are often used to compensate for minor misalignment and offset. The design is chemical and abrasion resistant accommodates for higher pressures than the standard metal expansion joints and eliminates sediment buildup. They have an integrally flanged design where no gaskets are required and are designed to absorb noise, vibration, and shock. This single, wide arch, spool-type rubber expansion joint is provided with hot-dipped galvanized retaining rings.
