Professional Applications & Engineering Value
This SBR rubber flat washer is engineered to address critical challenges in industrial assembly, including vibration-induced loosening, fluid leakage, and surface damage. The polyester fiber filler reinforces the structure, preventing extrusion under high bolt loads and ensuring consistent performance in heavy-duty applications. With a Durometer 70A hardness, it provides the ideal balance of flexibility and resilience, creating reliable seals in plumbing, automotive, and machinery systems. The 1" ID and 2.5" OD dimensions ensure precise alignment with standard fasteners, while the black SBR rubber material offers excellent resistance to compression set, making it a cost-effective solution for long-term vibration isolation and gasketing needs.
Specification Summary & Compliance
This flat washer features an inner diameter of 1", outer diameter of 2.5", and thickness range of 0.110-0.140". Manufactured from SBR rubber with polyester fiber filler, it maintains a Durometer 70A hardness and operates effectively up to 170°F maximum temperature. The product is fully compliant with RoHS 3 (2015/863/EU) regulations, ensuring it meets the latest environmental and safety standards for industrial components.
