• Durable Metal Bonding: Permanent adhesion between aluminum and neoprene prevents seal dislodgement, extending service life under dynamic loads.
• Versatile Industrial Application: Ideal for electrical enclosures, automotive systems, and machinery where vibration resistance and environmental sealing are critical.

Professional Applications & Engineering Value

This aluminum washer with a bonded neoprene seal addresses common industrial challenges such as fluid ingress, thermal cycling, and vibration-induced failures. The metal-bonded construction ensures the neoprene rubber remains securely attached, providing a consistent sealing barrier that compensates for surface irregularities. With a temperature range of -40°F to 250°F, it performs reliably in outdoor equipment, HVAC systems, and automotive components exposed to seasonal extremes. The black neoprene seal offers UV and ozone resistance, while the aluminum washer body resists corrosion, reducing maintenance needs. Engineers value its compliance with RoHS and REACH for global supply chain integration, making it a trusted choice for No. 10 screw applications demanding durability and regulatory adherence.

Specification Summary & Compliance
