S-5916K53 0.75" ID x 2" OD Chemical-Resistant Cushioning Washers

Key Features & Benefits at a Glance

• Superior Sealing Performance: The precision raised grid pattern creates multiple sealing lines, ensuring excellent fluid and gas containment for leak-proof applications.
• Exceptional Chemical & Temperature Resistance: Made from Buna-N rubber, this washer withstands oils, fuels, and temperatures up to 200°F, ensuring long-term reliability in harsh environments.
• Optimal Vibration Damping & Shock Absorption: The Durometer 63A hardness provides the perfect balance of flexibility and resilience, effectively isolating vibration and reducing noise.
• Enhanced Grip and Anti-Loosening: The interlocking grid design increases surface friction, preventing the fastener from loosening under dynamic loads and vibration.
• Precision Inch Sizing for Easy Installation: With a 0.75" ID and 2" OD, it's designed to fit standard 3/4" screws perfectly, simplifying assembly and ensuring a correct fit.
• Durable & Consistent Performance: The controlled thickness (0.469-0.531") and grid dimensions guarantee uniform compression and reliable performance in every use.
• Compliant for Global Industrial Use: Meets RoHS 3 and REACH standards, making it suitable for regulated industries and international supply chains.

Professional Applications & Engineering Value

This Buna-N rubber raised grid washer is engineered to solve critical challenges in industrial sealing and vibration isolation. The raised grid design is not merely a surface feature; it acts as a multi-point seal that compensates for minor surface irregularities on flanges and mating surfaces, preventing fluid ingress and leakage in pump systems, hydraulic assemblies, and automotive engines. Constructed from Buna-N (Nitrile Rubber), it delivers outstanding resistance to a wide range of hydrocarbons, oils, and water, making it indispensable in applications exposed to lubricants and fuels. Its Durometer 63A hardness provides optimal compressibility, ensuring effective vibration damping that protects sensitive components from fatigue and failure. This combination of a robust sealing mechanism and durable material offers a reliable, long-lasting solution for heavy-duty industrial applications where failure is not an option.
