Professional Applications & Engineering Value
Engineered for industrial applications requiring superior sealing and vibration resistance, this SBR rubber flat washer delivers critical performance where metal washers fall short. The polyester fiber reinforcement provides exceptional dimensional stability under compression, preventing extrusion in high-pressure bolted connections. With Durometer 70A hardness, it offers optimal flexibility for conforming to irregular surfaces while maintaining sufficient rigidity for load distribution. The black SBR rubber material resists degradation from oils, weather, and aging, making it ideal for automotive assemblies, machinery mounts, plumbing systems, and electrical enclosures where vibration damping and environmental sealing are paramount. Its temperature resistance up to 170°F ensures reliable operation in heated industrial environments.
Specification Summary & Compliance
This flat washer features inch system dimensions with 0.375" internal diameter, 1" outer diameter, and thickness ranging 0.110-0.140". Manufactured from SBR rubber with polyester fiber filler at Durometer 70A hardness, it's designed for 3/8" screw applications. The product complies with RoHS 3 (2015/863/EU) regulations and maintains performance across a temperature range up to 170°F, meeting industrial requirements for chemical resistance and environmental safety standards.
