DIN 11851 Blue Seal (Rubber)

• Material Composition: Made from food-grade rubber, the blue rubber seal is chosen for its excellent compatibility with various chemicals and its suitability for use in food, beverage, and pharmaceutical industries. The blue color is often used to help ensure visibility and detectability in processing environments.
• Sealing Efficiency: The rubber seal is specifically designed to create an airtight and watertight seal between the coupling faces of DIN 11851 fittings. This efficient sealing prevents leaks, maintains pressure stability, and ensures the integrity of fluid transfers, which is crucial in sanitary applications.
• Temperature and Chemical Resistance: These rubber seals are capable of withstanding a wide range of temperatures and are resistant to many chemicals, making them suitable for various processing conditions. This versatility is essential for maintaining operational reliability across different media and environmental conditions.
• Hygienic Design: The smooth and non-porous surface of the rubber minimizes sites where bacteria can harbor, contributing to the overall hygiene of the processing system. The use of food-grade materials ensures that the seals do not contaminate the products they come into contact with.

DIN 11851 fittings, known for their hygienic design and secure sealing capabilities, are specifically crafted for use in industries where sanitary conditions are crucial. These fittings feature a union that consists of a round slotted nut, a male part, a liner, and a seal, which are standardized according to German DIN standards.

• Food and Beverage Industry: DIN 11851 fittings are extensively used in food processing and beverage production facilities for connecting piping and equipment. They facilitate the sanitary transfer of edible products like dairy, juices, sauces, and other liquid foods.
• Dairy Industry: These fittings are integral in dairy processing plants, used in systems handling milk, cream, and other dairy products to ensure hygienic conditions and prevent contamination during processing and transfer.
• Brewing Industry: In breweries, DIN 11851 fittings are employed for connecting stainless steel pipes and hoses used in brewing, fermentation, and bottling processes. Their hygienic design is crucial for maintaining the quality and purity of beer.
• Pharmaceutical Manufacturing: DIN 11851 fittings are used in pharmaceutical production, particularly in processes that require sterile conditions, such as in the manufacturing of medicines, vaccines, and other sensitive pharmaceutical products.
• Wine Production: In the wine industry, DIN 11851 fittings are used in grape processing, fermentation tanks, and wine transfer lines, where their ability to maintain a clean and secure environment helps preserve the taste and quality of the wine.
