Professional Applications & Engineering Value
This Santoprene rubber flat washer is engineered to address common industrial challenges such as fluid leakage, component corrosion, and mechanical failure under extreme temperatures. Its black Santoprene material offers inherent resistance to chemicals, ozone, and weathering, making it ideal for applications in automotive, HVAC, and machinery where sealing performance is critical. The 64A durometer hardness provides a balance of softness for effective vibration dampening and firmness to maintain seal integrity under pressure. With an ID of 0.29" and OD of 0.562", it ensures a secure fit for 5/16" screw applications, reducing the risk of loosening and enhancing overall system reliability in high-temperature and chemical-exposed environments.
Specification Summary & Compliance
