Professional Applications & Engineering Value

This polyurethane rubber flat washer is engineered to address common industrial challenges such as metal-on-metal corrosion, vibration-induced fastener failure, and thermal expansion mismatches. Its clear polyurethane material provides excellent resistance to compression set, making it ideal for gasketing, sealing, and insulation applications in machinery, electrical enclosures, and plumbing systems. The Durometer 70A hardness ensures it absorbs shock without deforming permanently, while the temperature range from -10°F to 150°F allows reliable operation in both outdoor and heated industrial settings. By maintaining a secure fit on 1" screw sizes, it extends equipment lifespan and reduces maintenance frequency.

Specification Summary & Compliance

This flat washer conforms to inch system dimensions with an ID of 1.063", OD of 3", and thickness tolerance of 0.110-0.140". It meets industry standards for material performance and is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in regulated industrial and commercial applications.
