Metal Detectable O-Rings Gaskets and Seals

Metal Detectable O-Rings, Gaskets and Seals are used in the food and beverage industry to meet stringent safety standards during the manufacturing process.  Unlike other industries where chemical or temperature resistance is the key criteria in the selection of a sealing solution, food and pharmaceutical applications must also meet strict hygiene challenges.

Metal detectable sealing solutions help reduce the risk of product contamination by early detection and containment of contamination.  They decrease the risk of polymers finding their way into the finished product and supply chain.

Over time, processing equipment components in food, beverage, and pharmaceutical applications can degrade.  As elastomer seals degrade, there is an increased risk of rubber fragment contamination.  If the rubber from a standard seal were to break down and find its way into the product, it would be extremely difficult – if not impossible, costly and very time-consuming to detect.  If you are using standard seals, you must consider changing to metal detectable seals to manage your operational and product risk.

What Are Metal Detectable O-Rings, Gaskets and Seals Made From?

Metal detectable gasket and seals are manufactured from Silicone, Nitrile, EPDM and FKM compounds combined with ingredients which are visible to metal detectable scanning equipment.  Should a fragment of elastomer be detected, the production line can be stopped immediately, and any contaminated products can be quickly removed, well before they reach the supply chain.  Fragments as small as 2mm can be identified by metal detector equipment.

Benefits of Metal Detectable O-Rings, Gaskets and Seals

The following are benefits of using Metal Detectable sealing solutions:

  • Easily detect lost elastomeric fragments
  • Reduce production downtime
  • Prevent product recall
  • Reduces product loss
  • Stops distribution of contaminated product

Kemtron can supply metal detectable O-rings and gaskets that:

  • complies with regulation (EC) No 1935/2004 for articles intended to come into contact with food
  • conforms to US FDA 21 CFR177.2600 for rubber articles intended for repeated use with food

Our metal detectable seals are designed for microbial, high-temperature and mechanical applications.  They can easily substitute standard seals used in OEM equipment.
