Style 1101LW

General Rubber’s Style 1101LW lightweight rubber expansion joints are designed with lower spring rates for reduced reaction forces and greater movement capabilities within a compact body. This optimally designed lightweight construction represents the most cost-effective arrangement for low pressure applications. The construction includes full rubber flanges, a high-grade leak-proof tube, a seamless cover, multiple layers of high-strength tire cord and hot dip galvanized steel retaining rings. Additionally, they are designed to absorb large all-directional movements, reduce noise and vibration, have a cycle life in the tens of millions, compensate for misalignments, provide access to piping and equipment and relieve pipe and anchor stresses.
