Seals for the Food Industry
O-rings create an airtight or fluid-resistant seal between two surfaces, usually between a static surface and a moving one. Due to their versatility, efficacy, and durability, they are used in a wide variety of applications in different industries, one of them being the food industry, where they play an essential role in ensuring safety, quality, and efficiency in food production and processing.
They help prevent cross-contamination between different ingredients, preventing chemicals, bacteria or external contaminants from coming into contact with food during the production and packaging process.
Compliance with regulations
They comply with strict regulations regarding hygiene and food safety, helping to prevent leaks and ensure that equipment and systems meet necessary standards.
Prevention of waste
They prevent leaks of costly ingredients, such as liquids, oils, or chemicals, which reduces the waste of raw materials and saves costs.
Efficiency in production
They allow more efficient operation of equipment and systems used in food production. This can include pumps, piping, tanks and ingredient transport systems.
Maintenance of quality
They help maintain the quality of food by preventing oxidation, loss of flavor and aroma, and exposure to unwanted environmental conditions during production and storage.
Resistance to temperatures
They withstand a wide range of temperatures and chemicals, from extremely low temperatures in freezing to high temperatures in cooking processes.
Homologaciones y certificaciones más comunes
Common Approvals and Certifications: Some of the most common approvals and certifications requested for seals and components in the food industry include:
FDA (United States Food and Drug Administration): FDA approval is essential for materials in contact with food in the United States. It ensures that materials are safe and suitable for use in the food industry.
European Union Regulation (EC) No 1935/2004: In the European Union, this regulation establishes the requirements for materials and objects intended to come into contact with food. Materials must comply with the standards for chemical migration and be safe for human health.
European Union Certification (CE): The CE mark indicates that a product complies with the health, safety, and environmental protection requirements established by the European Union. This is important for exports and marketing of seals in the European market.
NSF International Certification: NSF International is an independent certification organization that evaluates and certifies products related to food safety, including seals and components used in the food industry.
3-A Sanitary Standards: This certification applies to equipment and components used in the production of food and pharmaceutical products. It ensures that materials meet rigorous hygiene and cleanliness standards.
Moreover, we are registered in the census of food establishments of the Basque Country (REACAV) with Registration No. 39.006030/BI within the sector 'Materials and objects intended to come into contact with Food'.
The choice of appropriate approvals and certifications depends on local and regional regulations, as well as the specific needs of the products and processes of each company in the food industry. These certifications help ensure the reliability and safety of the components used in food production and processing.

What are the most commonly used seals in this food industry?
Silicone or EPDM O-rings: widely used in the food industry due to their flexibility, resistance to extreme temperatures, and compatibility with food. They are used in pumps, valves, and pipe connections.
PTFE O-rings: widely used in valves and pumps to control the flow of liquids and prevent leaks.
X-Rings: made of elastomers such as nitrile rubber, they are used in shaft seals and bearings in food processing equipment to prevent the entry of external contaminants and lubricants.
Encapsulated O-rings: combine the chemical resistance of a PTFE core with the elasticity of an elastomer layer, making them suitable for applications where chemical resistance and effective sealing are required.
Metal and Rubber Seals: seals that combine metal and elastomer to provide mechanical strength and effective sealing. They are used in processing equipment that experiences high pressures and temperatures.
