Professional Applications & Engineering Value
This clear polyurethane rubber flat washer delivers exceptional engineering value through its unique material properties and precision manufacturing. The polyurethane rubber material provides superior resistance to oils, chemicals, and environmental factors that typically degrade standard rubber washers. With its Durometer 70A hardness, this washer maintains optimal compression set resistance while creating effective seals against moisture and contaminants. The transparent design allows for visual verification of proper installation and wear assessment during maintenance cycles. Engineered specifically for No. 4 screw applications, this flat washer effectively absorbs vibration and prevents loosening in electrical enclosures, instrumentation, and precision mechanical assemblies where reliable sealing and component protection are critical.
Specification Summary & Compliance
This flat washer features precise inch dimensions with 0.125" ID, 0.206" OD, and thickness ranging from 0.026" to 0.036" to ensure proper fit and function. Manufactured from high-grade polyurethane rubber with Durometer 70A hardness, the component maintains dimensional stability across its specified temperature range of -10°F to 150°F. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components.
