Professional Applications & Engineering Value
This SBR rubber flat washer is engineered to address common sealing and vibration challenges in industrial assemblies. The polyester fiber reinforcement significantly enhances structural integrity, preventing deformation under load and extending the washer's lifespan in high-stress applications. With a Durometer 70A hardness, it offers ideal flexibility for creating tight seals while dampening vibrations in machinery, automotive, and plumbing systems. The material's inherent chemical resistance protects against degradation from oils and solvents, making it suitable for industrial sealing in harsh environments. Its ability to withstand temperatures up to 170°F ensures reliable performance in equipment exposed to moderate heat, reducing maintenance needs and downtime.
Specification Summary & Compliance
This washer features an inner diameter of 0.77", outer diameter of 1.125", and thickness ranging from 0.047" to 0.077", designed for use with 3/4" screws in inch-based systems. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial components.
