Professional Applications & Engineering Value

These clear polyurethane rubber flat washers deliver exceptional engineering value through their unique material properties and precise dimensional control. The polyurethane rubber construction offers superior resistance to oils, chemicals, and environmental factors that typically degrade standard rubber compounds. With a Durometer 70A hardness rating, these washers provide optimal compression and recovery characteristics, making them ideal for applications requiring consistent sealing performance and vibration isolation. The transparent nature allows maintenance teams to visually inspect for proper installation and wear without disassembly. Commonly specified in industrial machinery, electronic enclosures, and precision equipment, these washers solve critical challenges in environments where both chemical resistance and vibration damping are paramount for operational reliability.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.286" inner diameter and 0.375" outer diameter, these flat washers maintain consistent thickness between 0.053" and 0.073" for reliable performance. The inch system measurement ensures compatibility with standard 1/4" fasteners. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees these components meet the latest environmental and safety standards for industrial applications worldwide.
