Professional Applications & Engineering Value

These neoprene rubber flat washers deliver critical engineering solutions where vibration damping and environmental sealing are paramount. The Durometer 55A hardness provides optimal balance between flexibility and compression resistance, effectively absorbing shock and preventing loosening in machinery, automotive, and electrical enclosures. Their temperature resistance from -20°F to 180°F ensures reliable performance in both freezing and moderate heat conditions, while the precise 0.49" ID and 1.062" OD dimensions guarantee proper fit for 1/2" screw applications. This combination addresses common industrial pain points including equipment wear, seal failure, and maintenance downtime.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.49" inner diameter, 1.062" outer diameter, and thickness range of 0.078-0.108". These flat washers comply with inch measurement system requirements for 1/2" screw size applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and restricted substance adherence for industrial use.
