Professional Applications & Engineering Value

Engineered specifically for food industry applications, these Buna-N rubber flat washers solve critical sealing challenges where temperature fluctuations and chemical exposure compromise equipment reliability. The FDA compliant formulation prevents material degradation when contacting food substances, while the Durometer 55A hardness provides sufficient compression to create leak-proof seals around No. 4 screw connections without causing surface damage. Their chemical resistance extends service life in environments requiring frequent sanitation, making them ideal for food processing machinery, packaging equipment, and commercial kitchen installations where regulatory compliance and operational safety are paramount.

Specification Summary & Compliance

This flat washer meets dimensional specifications with 0.313" OD, 0.12" ID, and thickness range of 0.019-0.043" for No. 4 screw size applications. Manufacturing adheres to FDA 21 CFR 177.2600 for food contact materials, RoHS 3 (2015/863/EU) for hazardous substance restriction, and REACH (EC 1907/2006) compliance regarding chemical registration and assessment. The Buna-N rubber material maintains consistent performance across the specified temperature range while providing reliable sealing in inch system assemblies.
