Poly Disc Couplings (COUP DISC POLY 2 5/8 008030)

COUP DISC POLY 2 5/8 008030|POLY-DISC flexible couplings use a non-metallic disc molded of a polyurethane compound to transmit torque. A special heat treatment after molding, refines the physical properties of the disc that allow it to remain pliable to cushion shock loads and still have resistance to most common chemicals such as acids, alkalis and petroleum products. The disc has an operating temperature range of -90 ? F to +170 ? F.
