CLEVIS INSULATOR (17B)The CLEVIS INSULATOR ensures electrical isolation from the carrier pipe and its support. In the event the pipe were to contact the hanger the clevis insulator prevents any metal contact between the main's clevis hanger and any supporting structures. The insulators are generally used in conjunction with Non-Conductive Rollers on clevis hangers because even minor alignment problems frequently result in pipe to hanger contact. Clevis insulator collars and bushings are fabricated from DuPont Delrin™, washers are stainless steel.
