Professional Applications & Engineering Value
These EPDM rubber flat washers deliver critical sealing performance in demanding industrial environments where temperature fluctuations and chemical exposure compromise ordinary components. The Durometer 65A hardness provides ideal compression characteristics for creating reliable seals without over-compression that could lead to failure. Engineered for 3/8" screw applications, these black rubber washers effectively prevent fluid ingress, dampen vibration, and compensate for surface irregularities in plumbing, HVAC, automotive, and electrical enclosures. The temperature resistance from -20°F to 212°F ensures consistent performance in both freezing conditions and high-heat environments, while the EPDM material offers excellent resistance to weathering, ozone, and steam degradation.
Specification Summary & Compliance
This flat washer features precise inch system dimensions with 0.355" ID, 0.812" OD, and thickness ranging 0.078-0.108" for consistent 3/8" screw compatibility. Manufactured from EPDM rubber with Durometer 65A hardness for optimal sealing performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial applications worldwide.
