Professional Applications & Engineering Value

This Neoprene rubber flat washer is engineered to solve critical challenges in industrial sealing and mechanical isolation. Its black Neoprene composition provides inherent resistance to water, oils, and weathering, making it an ideal sealing washer for outdoor equipment, automotive panels, and plumbing fixtures. The 55A Durometer hardness ensures it compresses effectively to create a tight seal under 5/8" screw heads without over-deforming, while its vibration dampening properties protect sensitive components from fatigue and loosening in machinery and electrical enclosures. With a temperature range of -20°F to 180°F, it performs reliably in varied climates, from freezer units to engine compartments, reducing maintenance needs and enhancing assembly integrity.

Specification Summary & Compliance

This flat washer conforms to inch system dimensions with an Inside Diameter of 0.615", Outside Diameter of 1.312", and Thickness of 0.110-0.140", designed for use with 5/8" screw size. It is manufactured from Neoprene rubber with a Durometer 55A hardness and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring adherence to environmental and safety regulations for industrial components.
