1-1/4" ID x 2" OD x 1/8" EPDM Rubber Flat Washers Non-Conductive Electrical Isolation Auto Repair Battery Terminal 5 Pack

These EPDM rubber flat washers provide electrical isolation, cushioning, and surface protection for automotive, powersports, and electrical mounting applications. The 2" outside diameter distributes clamping force over a larger surface while helping reduce vibration and preventing metal-to-metal contact. The 1/8" thickness provides durable cushioning for battery terminals, grounding points, wiring brackets, chassis hardware, and electrical enclosures. EPDM rubber offers excellent resistance to water, moisture, UV exposure, ozone, and temperature extremes. Commonly used for battery connections, chassis grounds, electrical panels, wiring mounts, equipment brackets, and general maintenance where a non-conductive spacer is required. Material properties are provided for general reference only. Buyers are responsible for verifying suitability for their specific application.
