Professional Applications & Engineering Value
This PEEK plastic flat washer delivers critical solutions for demanding industrial settings where metal components fail. Its high-temperature resistance up to 500°F prevents deformation in thermal cycling applications, while the low-temperature flexibility down to -50°F maintains seal integrity in cryogenic environments. The chemical-resistant PEEK material withstands aggressive solvents and oils, eliminating corrosion and galvanic issues common in metal washers. With precise inch system dimensions (0.141" ID x 0.35" OD) for No. 5 screws, it ensures perfect fitment in aerospace, automotive, and semiconductor equipment where dimensional stability and electrical insulation are paramount. The Rockwell M103 hardness provides lasting surface protection against embedment and wear.
Specification Summary & Compliance
This flat washer features precise inch system dimensions with 0.141" inner diameter, 0.35" outer diameter, and thickness ranging 0.036-0.045" for consistent performance. Manufactured from high-performance PEEK plastic with Rockwell M103 hardness rating, it maintains dimensional stability across the specified temperature range. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance for global industrial applications.
