Metal Detectable O-Rings & Seals

Custom sizes and materials are available. Please talk to a sales representative for more details.

Specifically developed to meet the stringent demands of the food and pharmaceutical industries, Detectamet's metal detectable O-rings help reduce the risk of product contamination by early detection and containment of contamination.

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.

Metal detectable O-rings and seals are easily detected by most conventional metal detection techniques that are already in place on production lines. 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.

Detectamet supply a range of metal detectable O-rings and seals manufactured from Silicone, Nitrile, EPDM and FKM compounds. The seals are available in blue or black for easy product identification, and offer extended lifetime performance.

Metal Detectable Nitrile Buna-N (NBR): the most widely used elastomer for O-rings with excellent resistance to petroleum based oils and fuels, silicone greases, hydraulic fluids, water and alcohols. A great balance of working properties such as low compression set, high tensile strength, high abrasion resistance, combined with a low material costs. Temperature range -25°C to +110°C, shore hardness 70.

Metal Detectable FKM Viton: exceptional resistance to high temperatures up to 200°C and aggressive fuels & chemicals. Viton is commonly used for O-rings, as well as rotary shaft seals & gaskets. Temperature range -15°C to +200°C, shore hardness 70.
