5/8" ID Round EPDM Rubber Flat Washers 1" OD x 1/8" Thick Gasket Spacers for Plumbing, HVAC, Automotive, Marine, Electrical Insulation, Vibration Dampening 5/8 x 1 x 1/8 (24)

5/8" ID x 1" OD x 1/8" thick EPDM rubber flat washers designed for use with a wide range of fasteners in both industrial and household applications. These washers are ideal for sealing, spacing, insulating, and absorbing vibration across plumbing, HVAC, marine, electrical, and automotive systems. Die-cut from EPDM rubber, they offer strong resistance to water, UV, ozone, and weathering. Commonly used in compressors, motors, pumps, valves, and equipment exposed to outdoor or aquatic environments. They help prevent leaks, reduce shock, and insulate sensitive components from electric or thermal transfer. Rubber washers are also effective for noise reduction and surface protection in machinery with moving parts. Their non-abrasive nature helps extend the life of surrounding materials, making them a reliable solution for frequent-use assemblies. 5/8" Inside Diameter, 1" Outside Diameter, 1/8" Thickness – Compatible with standard fasteners EPDM material – Excellent resistance to water, UV, ozone, and environmental stress Used as gaskets, spacers, insulators, or shock absorbers in industrial and DIY setups Ideal for plumbing, HVAC, marine, electronics, automotive, and outdoor equipment Supports mechanical assemblies by isolating vibration, sealing joints, and preventing wear
