If these O-rings deteriorate they can be picked up by metal detection systems. Made of Buna-N rubber, they resist animal oil, vegetable oil, and water. O-rings are sized to the SAE standard AS568. All include material certification with shelf life, test report, and traceable lot number.
Metal detectable O-Rings and Rubber Seals are used with detection equipment to identify contamination. Over time and repeated clean in place, sterilization, and processing equipment components in food, beverage, and pharmaceutical processing equipment can degrade. As elastomer seals degrade, there is a high risk of rubber fragment contamination. Metal detectable O-rings and Seals are designed to work with Inline X-ray detection, Metal detection and Magnetic separator equipment for immediate contamination alert. Different base materials like FKM, Silicone, EPDM and Buna-N are filled with a unique combination of magnetic metallic fillers so easily detectable allowing systems to quickly reject contaminated product and trigger equipment PM to drastically reduce the potential of contamination of the final product. We have found the metal detectable O-Ring and Seal market is NOT one material fits all detection equipment and requirements. If the more popular materials do not work, Marco Rubber is equipped to offer fast prototype runs of custom formulated materials to confirm performance.
