S-94240A112 0.33" ID x 0.68" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Exceptional temperature resilience with a wide operating range from -40°F to 250°F, ensuring reliable performance in both freezing and high-heat industrial environments.
• Superior sealing integrity provided by the bonded neoprene rubber seal with Durometer 65A hardness, which offers excellent compression set resistance and maintains a tight seal against moisture, dust, and contaminants.
• Lightweight corrosion resistance due to the aluminum construction, reducing overall assembly weight while providing inherent protection against rust and oxidation in harsh conditions.
• Precise dimensional compatibility with a 0.33" ID and 0.68" OD, engineered to fit 5/16" screws perfectly, ensuring easy installation and uniform load distribution.
• Durable metal-to-rubber bonding that prevents seal separation under vibration or pressure, extending service life and reducing maintenance needs in dynamic applications.
• Regulatory compliance assurance with RoHS 3 and REACH standards, guaranteeing the washer is free from hazardous substances and safe for use in regulated industries.
• Versatile industrial suitability thanks to the black neoprene seal and aluminum body, which resist UV exposure, oils, and weathering, making them ideal for outdoor or chemically exposed settings.

Professional Applications & Engineering Value

This aluminum washer with a neoprene seal is engineered to address common challenges in industrial sealing, such as fluid ingress, thermal expansion, and fastener loosening. The metal-bonded design integrates a flexible neoprene rubber seal (Durometer 65A) with a rigid aluminum washer, creating a robust barrier that maintains compression under varying pressures and temperatures. Ideal for applications in automotive assemblies, HVAC systems, and outdoor machinery, it solves pain points like corrosion-induced failure and seal degradation. By combining lightweight aluminum with a temperature-resistant seal, it ensures long-term reliability in environments exposed to moisture, chemicals, or thermal cycling, reducing downtime and replacement costs for B2B users.
