Professional Applications & Engineering Value
Engineered for demanding industrial environments, these M18 metric flat washers solve critical sealing and insulation challenges where conventional materials fail. The fluorosilicone rubber composition delivers outstanding resistance to fuels, oils, solvents, and extreme temperatures (-80°F to 450°F), making them ideal for automotive, aerospace, and chemical processing applications. Their precise 19mm ID x 34mm OD dimensions ensure perfect fit with M18 fasteners while the Durometer 60A hardness provides optimal compression recovery and vibration dampening. These blue washers maintain sealing integrity in high-temperature assemblies, preventing fluid leaks and electrical conductivity in harsh operating conditions where thermal cycling and chemical exposure would degrade standard rubber components.
Specification Summary & Compliance
Manufactured to precise metric dimensions with 19mm internal diameter and 34mm outer diameter, these flat washers feature a controlled thickness range of 1.32mm-1.82mm for consistent performance. The fluorosilicone rubber material meets industry standards for high-temperature applications with Durometer 60A hardness rating. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for global industrial use.
