Professional Applications & Engineering Value
These neoprene rubber flat washers deliver critical sealing performance in demanding food industry applications where contamination prevention is paramount. The FDA-compliant 21 CFR 177.2600 material formulation resists degradation from food substances, sanitizing chemicals, and thermal cycling between -30°F and 220°F. Engineered with 55A durometer hardness, these flat washers provide consistent compression recovery that maintains seal integrity under vibration and pressure fluctuations. The white rubber construction offers visual cleanliness monitoring while the precise 0.29" ID and 0.688" OD dimensions ensure proper seating on 5/16" fasteners, preventing leakage points in processing equipment, mixing assemblies, and food handling machinery.
Specification Summary & Compliance
This flat washer features inch system dimensions with 0.29" internal diameter, 0.688" outer diameter, and 0.062" thickness specifically engineered for 5/16" screw size applications. Manufactured to FDA compliance standard 21 CFR 177.2600 for food contact surfaces, with additional conformity to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives. The neoprene rubber material maintains consistent performance across the specified temperature range while providing the durability required for industrial sealing applications.
