Contamination Detection and Pharmaceutical Processing
Metal detectable O-Rings and Rubber Seals are used with detection equipment to identify contamination. With time and repeated cleaning, sterilization and processing equipment components in food & beverage, and pharmaceutical processing equipment can degrade.
As elastomer seals degrade, there is an elevated 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 identification.
A variety of base materials like FKM, Silicone, EPDM and Buna-Nitrile are filled with a unique combination of magnetic metallic fillers for detectability. This allows systems to quickly reject contaminated products and trigger equipment PM to drastically reduce the potential of contamination of the final product.
Marco Rubber supplies metal detectable o-rings, seals, sanitary gaskets, x-rings, and any custom shape desired. We know metal detectable O-Rings and Seals are NOT a one material fits all sealing solution. If our popular materials do not meet your requirements, Marco Rubber is equipped to offer prototypes of custom formulated materials to match the performance you seek.
Metal detectable o-rings and seals are in stock and available to buy online. For assistance with material selection or custom materials, contact us to consult with an expert.

The information on this page is to the best of our knowledge accurate and reliable. However, Marco Rubber makes no warranty, expressed or implied, that parts manufactured from this material will perform satisfactorily in the customer's application. It's the customer's responsibility to evaluate parts prior to use.
The temperature ranges presented on this page are approximations for dry air service only and should not be used to determine design specifications or end-use temperature limits. Actual temperature range of a compound in an end-use application is highly dependent on part type, hardware configuration, applied forces, chemical media, pressure and thermal cycling effects, and other factors. The most practical way of determining an end-use temperature range is testing in the actual application conditions. Consult a Marco Engineer for more details.
