Rubber Washers

Used for sealing, spacing, and vibration control in plumbing, automotive, electrical, and general hardware applications. Non?conductive rubber construction provides a stable seal against metal or plastic surfaces and supports equipment where cushioning and moisture resistance are required.

Used for spacing, mounting, vibration control, and electrical insulation in automotive, marine, industrial, and electronic assemblies. Commonly used as rubber spacers, EPDM washers, vibration dampeners, and non?conductive rubber bushings for bolts, brackets, panels, and machinery. Made from high?density EPDM rubber with a medium?firm durometer that provides compression strength, shock absorption, and long?term flexibility. The material resists weather, UV, ozone, water, salt, and common automotive fluids while maintaining stability across a wide temperature range. Installs easily with bolts, screws, studs, or brackets and performs reliably in indoor and outdoor environments. Suitable for compressors, motors, lighting fixtures, electronics, marine equipment, and general fabrication. Multiple inside diameters, outside diameters, thicknesses, and pack quantities are available.
