Professional Applications & Engineering Value

These EPDM rubber flat washers deliver exceptional engineering value through their specialized material properties and precise dimensional specifications. The EPDM rubber construction provides outstanding resistance to weathering, UV exposure, and compression set – critical factors where traditional materials fail. With their 0.141" ID perfectly matched to No. 5 screws, these washers eliminate installation issues while the 0.281" OD provides adequate bearing surface. The Durometer 60A hardness ensures optimal sealing without over-compression, making them ideal for electrical enclosures, plumbing connections, automotive assemblies, and HVAC systems where reliable sealing against moisture and environmental elements is paramount. Their ability to maintain performance across extreme temperature fluctuations from -40°F to 212°F makes them suitable for both indoor and outdoor industrial applications.
