1/4" ID x 1-1/2" OD x 1/16" EPDM Rubber Flat Fender Washers, Non-Conductive Washers for Electrical Panels, Control Cabinets, Junction Boxes & Equipment Enclosures (10 Pack)
Industrial EPDM rubber flat fender washers designed for electrical equipment, enclosure hardware, and general maintenance applications. The large 1-1/2" outside diameter helps distribute clamping force across a wider surface area while providing cushioning and surface protection under mounting hardware. EPDM rubber creates a non-conductive barrier between fasteners and mounting surfaces, making these washers suitable for electrical panels, control cabinets, junction boxes, and equipment enclosures. The all-weather EPDM material resists moisture, UV exposure, ozone, and temperature extremes commonly encountered in indoor and outdoor service environments. These washers help reduce vibration, minimize metal-to-metal contact, and protect painted, coated, and finished surfaces from wear caused by hardware movement and clamping pressure.
