Professional Applications & Engineering Value

These M5 metric flat washers engineered from premium fluorosilicone rubber address critical sealing challenges in demanding industrial environments. The specialized material composition provides outstanding resistance to extreme temperatures, chemicals, and compression set - solving common failure points in automotive, aerospace, and chemical processing equipment. With precise 5.3x10mm dimensions and 60A durometer hardness, these washers create reliable seals that maintain integrity under vibration and thermal cycling. The blue fluorosilicone rubber washers prevent fluid leakage in M5 fastener applications while withstanding aggressive media that would degrade standard elastomers, delivering extended service life and reduced maintenance costs in high-performance sealing applications.

Specification Summary & Compliance

Manufactured to precise metric dimensions with 5.3mm inner diameter and 10mm outer diameter, these flat washers feature a controlled thickness range of 1.320mm-1.820mm for consistent compression performance. The washers comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial applications. The fluorosilicone rubber material maintains its mechanical properties across the specified temperature range from -80°F to 450°F, providing reliable performance in accordance with industrial sealing requirements for M5 fastener systems.
