Professional Applications & Engineering Value

These Buna-N rubber flat washers deliver critical sealing solutions for food industry equipment where contamination prevention and chemical resistance are paramount. The FDA-compliant material formulation prevents leaching while maintaining flexibility across temperature extremes from freezer applications to hot washdown cycles. Engineered with precision inch dimensions (0.216" ID x 0.438" OD) for No. 12 screws, these washers create reliable seals on mixing equipment, filling machines, and processing conveyors. The 60A durometer hardness provides ideal compression recovery for repeated use, while the white coloration enables quick visual inspection for wear or contamination in regulated environments.

Specification Summary & Compliance

Manufactured to exacting dimensional standards with 0.216" inner diameter and 0.438" outer diameter in inch system measurements. These flat washers meet FDA 21 CFR 177.2600 for food contact applications and comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives. The Buna-N rubber construction maintains performance across the specified temperature range of -20°F to 175°F while providing consistent sealing capability for No. 12 screw applications in food processing and industrial equipment.
