FOOD COUPLINGS <strong>DIN</strong> <strong>11851</strong>W W W. L M C- C O U P L I N G S. C O MB.3.STANDARD<strong>Food</strong> <strong>couplings</strong> complying with <strong>DIN</strong> <strong>11851</strong> are used in the food, chemicaland pharmaceutical industries to connect rubber food hoses and stainlesssteel pipes (in compliance with <strong>DIN</strong> 11850).On request food <strong>couplings</strong> complying with <strong>DIN</strong> 11864 available.OPERATIONThe seal must be inserted correctly into the seal sitting of the male couplingbefore connection. The conical female coupling is then pushed onto themale threaded coupling. The two are secured by sliding the nut across theconical head of the female coupling and onto the thread of the male coupling.The flanged seal enables easy assembly and prevents any displacementby vacuum or pressure.Threaded food <strong>couplings</strong> complying with <strong>DIN</strong> <strong>11851</strong> have a rounded threadcomplying with <strong>DIN</strong> 405/1. This rounded thread ensures that <strong>DIN</strong> <strong>11851</strong>compliant food <strong>couplings</strong> are easy to connect by hand or using a wrench.FOOD COUPLINGS <strong>DIN</strong> <strong>11851</strong>FEATURES7.1.2.3.5.1.
