How to choose the ideal hygienic seal for your equipment

Hygienic Seals: reliable sealing in demanding hygienicprocesses

In sectors where cleanliness, safety, and sterility are non-negotiable—such as the pharmaceutical, food, cosmetics, or biotechnology industries—having certified, highly reliable components is key. In this context, hygienic seals are essential to ensure a hygienic, durable seal compatible with CIP/SIP cleaning systems.

At JIOrings we offer a wide range of hygienic seals in stock, manufactured from compounds that comply with the main international standards: FDA, USP Class VI, CE 1935/2004, among others. This makes us the ideal supplier for machine manufacturers, system integrators, and maintenance departments seeking certified, ready-to-ship solutions.

Available approvals and standards

When it comes to safety and hygiene in industrial processes, material certifications are crucial. All our hygienic seals can be manufactured from compounds that meet the strictest market standards:

• FDA (U.S. Food and Drug Administration)
• USP Class VI (biocompatibility for pharmaceutical applications)
• CE 1935/2004 (food contact compliance in the European Union)
• 3-A Sanitary Standards (equipment for the dairy industry)
• KTW-UBA (potable water applications, Germany)
• ACS (potable water approval, France)
• WRAS (potable water use, United Kingdom)
• EN 681-1 (sealing in hydraulic applications)

These certifications not only guarantee the chemical and thermal compatibility of materials but also ensure their safety and resistance to demanding use conditions.

Finally, remember that on the JIOrings online store you can easily purchase your hygienic seals with complete confidence. During the purchase process, you can not only select the type of seal but also easily add the certifications and/or approvals you require, such as FDA, USP Class VI, or CE 1935/2004. All in one step, quickly, clearly, and adapted to your application’s requirements.
