3/16" ID x 3/4" OD x 1/16" EPDM Rubber Flat Washers Electrical Isolation Control Panel Enclosure Vibration Dampening 25 Pack
3/16" ID x 3/4" OD x 1/16" EPDM Rubber Flat Washers Electrical Isolation Control Panel Enclosure Vibration Dampening 25 Pack
These 3/16" ID x 3/4" OD x 1/16" EPDM rubber flat washers are designed for electrical isolation, vibration reduction, and surface protection in industrial and commercial equipment. Manufactured from durable, non-conductive EPDM rubber, these precision die-cut washers provide reliable spacing, cushioning, and load distribution around 3/16" (5 mm) bolts, screws, and mounting hardware. The 3/4" outside diameter helps spread clamping force while protecting painted, coated, aluminum, and steel surfaces from metal-to-metal contact. EPDM rubber offers excellent resistance to moisture, ozone, UV exposure, and weathering, making these washers ideal for indoor and outdoor electrical installations. They help reduce vibration, rattling, and mechanical stress in control panels, electrical enclosures, instrumentation, HVAC controls, automation equipment, machinery, pumps, compressors, and general industrial MRO applications. Commonly used as electrical isolation washers, spacer washers, vibration dampeners, and protective mounting washers for junction boxes, control cabinets, electrical panels, equipment brackets, and fabrication projects.
