In food-grade industries, maintaining the highest level of safety, hygiene, and efficiency is of utmost importance. Union Metal‘s DIN 11851 fittings have emerged as a reliable solution for fluid connections in such industries, offering a range of benefits that contribute to seamless operations. This article will introduce the key features and advantages of our DIN 11851 fittings, focusing on their application in food-grade environments and their overall contribution to safety and hygiene.


Compliance with Sanitary Standards

Union Metal’s DIN 11851 fittings meet various sanitary standards, including DIN11850/11851, SMS1145, 3A, RJT, IDF, ISO, and MACON. These standards ensure that the fittings adhere to strict guidelines for cleanliness, quality, and safety. By conforming to these standards, Union Metal’s DIN 11851 fittings provide peace of mind to food-grade industries, assuring them of reliable and compliant fluid handling solutions.


High-Quality Materials

The fittings are manufactured using high-quality stainless steel 316L or 304, which offers excellent corrosion resistance and durability. The use of these materials ensures that the fittings can withstand harsh operating conditions, including exposure to corrosive substances and frequent cleaning processes. Stainless steel also eliminates the risk of contamination, as it does not react with food or beverage products, maintaining the integrity and quality of the fluids being handled.


Versatile Size Range and Customizability

Union Metal’s DIN 11851 fittings are available in sizes ranging from 1″ to 4″ (DN25 to DN100), providing flexibility to accommodate various pipe diameters in food-grade applications. Additionally, these fittings can be customized with custom sizes and logos, allowing businesses to align them with their specific requirements and branding.


Wide Range of Gasket Options

The fittings come with a choice of gaskets made from silicon rubber, EPDM, VITON, or PTFE. This variety enables businesses to select the most suitable gasket material based on the specific needs of their application. Gaskets made from these materials offer excellent sealing properties, ensuring leakage prevention and maintaining hygienic conditions during fluid transfer processes.


Applications in Food and Beverage Industries

Union Metal’s DIN 11851 fittings find extensive application in food, beverage, dairy, pharmaceutical, beer, biotechnology, and cosmetic industries. These fittings are designed to handle the unique challenges posed by these sectors, including the need for hygienic fluid connections, as well as resistance to corrosion and high pressures. The fittings facilitate smooth production processes, ensuring the safety, quality, and integrity of the end products.
