- Corrosion-resistant 18-8 stainless steel construction ensures long-term durability and chemical resistance in harsh industrial settings.
- Precise dimensional fit with 0.175" ID and 0.55" OD, designed specifically for No. 8 screws to prevent loosening and misalignment.
- Durable material hardness featuring Rockwell B80 metal and Durometer 50A silicone for consistent performance under mechanical stress.
- Regulatory compliance assurance with RoHS 3 and REACH adherence, meeting stringent environmental and safety standards.
- Easy visual identification through the green silicone seal, simplifying installation and maintenance checks.
Professional Applications & Engineering Value
This metal bonded washer combines the structural strength of 18-8 stainless steel with the flexibility of a silicone rubber seal, effectively solving common industrial challenges like fluid ingress, thermal expansion, and vibration-induced failures. Its robust design is engineered for high-temperature and cryogenic applications, such as HVAC systems, automotive assemblies, and chemical processing equipment, where maintaining a secure, leak-proof seal under fluctuating pressures and temperatures is critical. The bonded construction eliminates separate gaskets, reducing assembly time and enhancing reliability in demanding industrial environments.
Specification Summary & Compliance
This washer features precise dimensions: 0.175" ID, 0.55" OD, and thickness ranging from 0.047" to 0.109", tailored for No. 8 screw size applications. It adheres to industry standards with material hardness of Rockwell B80 for the metal and Durometer 50A for the seal, ensuring consistent performance. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming environmental safety and regulatory alignment for global industrial use.
