Professional Applications & Engineering Value
This metal bonded washer combines the structural integrity of 18-8 stainless steel with the flexibility of a silicone rubber seal, offering a robust solution for sealing challenges in industrial applications. The bonded design eliminates seal displacement, providing reliable performance in environments with thermal cycling, vibration, and exposure to fluids or gases. Engineers value its ability to maintain a tight seal under pressures up to 100 psi and across a wide temperature range from -100°F to 400°F, making it suitable for automotive, HVAC, and machinery assemblies where metric washers with integrated sealing are critical for preventing leaks and reducing maintenance costs.
Specification Summary & Compliance
This washer features precise dimensions: 2.9 mm ID, 25.4 mm OD, and 2-2.1 mm thickness, designed for M3 screw sizes in metric systems. The 18-8 stainless steel offers Rockwell B80 hardness, while the silicone seal has a Durometer 50A hardness for optimal compression. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory adherence for industrial use.
