- Consistent Durometer 60A hardness maintains sealing integrity and vibration dampening across the entire operating temperature range.
- Fluorosilicone rubber construction provides excellent chemical and oil resistance for harsh industrial applications.
- Precision dimensions (0.12" ID, 0.312" OD) ensure perfect fit and optimal sealing for No. 4 screws, reducing installation errors.
- Variable thickness (0.019-0.043") accommodates minor surface irregularities for improved sealing contact and pressure distribution.
- RoHS 3 and REACH compliance guarantees environmental safety and regulatory acceptance for global industrial supply chains.
- High-visibility blue color enables easy identification and quality control during assembly processes.
Professional Applications & Engineering Value
These fluorosilicone rubber flat washers deliver critical sealing solutions where standard washers fail. The fluorosilicone material combines silicone's flexibility with enhanced chemical resistance, making these flat washers ideal for automotive, aerospace, and chemical processing equipment exposed to fuels, oils, and extreme temperatures. The 0.12" ID precisely matches No. 4 screw requirements while the 0.312" OD provides sufficient bearing surface. Engineers specify these washers to prevent leakage, absorb vibration, and maintain seal integrity from -70°F to 450°F, solving common gasket compression set and thermal degradation issues in demanding industrial applications.
Specification Summary & Compliance
Manufactured to inch system standards with precise inner diameter (0.12" ID), outer diameter (0.312" OD), and thickness range (0.019-0.043") for No. 4 screw applications. These fluorosilicone rubber flat washers maintain Durometer 60A hardness throughout the specified temperature range. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety standards for industrial components.
