1" ID x 2-1/2" OD x 1/8" EPDM Rubber Flat Washers, Non-Conductive Vibration Dampening Spacer Washers for Truck, Trailer & Equipment Repair, 5 Pack

These EPDM rubber flat washers are designed for heavy-duty mounting, fleet maintenance, equipment support, and industrial repair applications. The large 2-1/2" (63 mm) outside diameter helps distribute load over a wider surface area while protecting painted, coated, and finished materials from hardware damage. EPDM rubber provides excellent resistance to moisture, UV exposure, ozone, and weathering. The non-conductive material also helps isolate vibration and reduce metal-to-metal contact. Commonly used under bolts, studs, brackets, equipment supports, protective covers, frame components, and mounting hardware requiring cushioning and surface protection. Suitable for truck and trailer service, fleet maintenance, fabrication work, industrial equipment repair, electrical enclosures, machinery installations, and general maintenance applications.
