Food Grade O-Ring Kits Available
International Seal supplies food grade O-ring assortments for a range of hygienic processing and maintenance requirements. Kits may contain commonly specified dimensions or be configured around particular machinery, product-contact conditions and elastomer specifications.
General Food Grade O-Ring Assortment Kits
General food grade O-ring kits provide selections of sealing dimensions for suitable food and beverage processing equipment. These assortments can support replacement requirements across compatible pumps, valves, fittings and processing assemblies where food-contact sealing components are specified.
Material grades and compliance documentation should be confirmed according to the intended application.
Food Grade Silicone O-Ring Kits
Food grade silicone O-ring kits contain selected silicone rubber sealing rings for applications requiring suitable food-contact properties and temperature resistance.
Silicone is commonly specified for selected food-processing equipment, hygienic assemblies and specialist sealing applications. Suitable compounds may be available with documentation supporting FDA or European food-contact requirements.
Food Grade EPDM O-Ring Kits
Food grade EPDM O-ring kits provide sealing selections for applications involving water, aqueous processing media and compatible cleaning conditions.
Suitable EPDM compounds are commonly used in hygienic equipment, dairy processing machinery and water-handling systems, subject to the required food-contact compliance and operating conditions.
Food Grade FKM O-Ring Kits
Food grade FKM O-ring kits contain selected fluoroelastomer sealing rings for demanding processing applications involving elevated temperatures, compatible oils and chemical exposure.
Food-contact suitable FKM compounds can be considered where increased chemical and thermal resistance is required. The selected compound must meet the relevant application and compliance specifications.
Metal Detectable O-Ring Kits
Metal detectable O-ring assortments can be configured using specialist elastomer compounds containing detectable additives.
These materials are used in selected food-processing applications where the ability to identify seal fragments within a detection system forms part of the facility’s contamination-control strategy.
Detectability depends on the compound, fragment size, equipment sensitivity and processing conditions. Suitability must be validated for the intended detection system.
Food Grade O-Ring Kit Materials
Food grade O-ring assortments can be specified using a range of elastomer materials selected according to the processing environment, operating conditions and relevant food-contact requirements.
| Material | Typical Food Processing Applications |
|---|---|
| Silicone | Food-processing machinery, hygienic equipment and suitable elevated-temperature sealing applications |
| EPDM | Dairy processing, aqueous food systems, water-handling equipment and compatible cleaning processes |
| FKM (Viton) | Elevated-temperature equipment, compatible oils, fats and specialist chemical processing applications |
| NBR (Nitrile) | Selected food-processing machinery, compatible oils and general equipment sealing requirements |
| Metal Detectable Elastomers | Food-production equipment requiring additional seal-fragment detection capabilities |
Suitable food-contact grades must be selected for each application. The designation of an elastomer as silicone, EPDM, FKM or NBR does not automatically establish food-contact compliance.
Material selection should consider operating temperature, pressure, cleaning procedures, chemical compatibility and any required regulatory documentation.
Food Grade O-Ring Compliance
O-rings used in food-processing equipment may be subject to specific food-contact material requirements depending on their intended use and the market in which the equipment operates.
FDA 21 CFR 177.2600
FDA regulation 21 CFR 177.2600 specifies requirements for certain rubber articles intended for repeated food-contact use in the United States. Suitable elastomer compounds may be formulated to comply with these requirements, subject to the relevant composition, extraction limits and conditions of use.
FDA compliance must be established for the specified material and application. It should not be assumed that every O-ring within a general assortment is compliant.
EU Regulation (EC) No 1935/2004
Regulation (EC) No 1935/2004 establishes the general framework for materials and articles intended to come into contact with food within the European Union. Applicable food-contact materials must satisfy the relevant regulatory requirements, including restrictions concerning the transfer of substances to food.
Regulation (EC) No 2023/2006 also establishes good manufacturing practice requirements for food-contact materials and articles. Specific elastomer compliance may require additional supporting assessments and documentation, depending on the material and intended use.
Food-Contact Documentation
Where food-contact compliance is required, International Seal can review available supplier documentation and material specifications during the quotation process. The relevant requirements should be confirmed before ordering, particularly where sealing components will be exposed to food products, elevated temperatures or repeated cleaning cycles.
Food Grade O-Ring Kit Applications
Food grade O-ring assortments are used across food and beverage production environments where suitable elastomer sealing components are required for machinery servicing, maintenance and replacement applications.
Food Processing Equipment
Food grade O-ring kits can support maintenance of compatible production machinery, processing assemblies and components operating within food-manufacturing environments.
