S-90130A080 0.99" ID x 2" OD Rubber Sealing Washers

Key Features & Benefits at a Glance

• Superior Sealing Performance: EPDM rubber construction provides excellent compression and recovery, creating reliable seals against moisture, dust, and air in industrial applications.
• Wide Temperature Resilience: Maintains flexibility and sealing integrity across an extensive range from -20°F to 212°F, suitable for both freezing and high-heat environments.
• Optimized Fit for 1" Screws: Precisely engineered 0.99" ID ensures secure fit and even pressure distribution, preventing loosening and damage to connected surfaces.
• Consistent Durability: Durometer 65A hardness offers the perfect balance of softness for sealing and firmness for long-term wear resistance under compression.
• Regulatory Compliance Assurance: Meets RoHS 3 and REACH standards, ensuring safe use in regulated industries without hazardous substances.
• Versatile Industrial Application: Black EPDM material resists weathering, ozone, and aging, ideal for outdoor equipment, plumbing, HVAC, and automotive assemblies.
• Dimensional Precision: 2" OD and controlled thickness (0.078-0.108") provide consistent performance and easy installation in inch-based systems.

Professional Applications & Engineering Value

This EPDM rubber flat washer solves critical engineering challenges in sealing and vibration management. The EPDM material delivers exceptional resistance to temperature extremes, UV exposure, and compression set, making it ideal for outdoor industrial equipment, plumbing systems, and HVAC applications where environmental factors degrade ordinary washers. Its Durometer 65A hardness ensures it conforms to irregular surfaces without losing sealing pressure, while the precise 0.99" ID for 1" screws prevents misalignment and distributes load evenly. Engineers specify this black rubber washer for its reliable performance in preventing leaks, reducing noise, and protecting metal surfaces from corrosion in demanding industrial washers scenarios.
