A DIN blank disc is a solid, circular stainless steel component used to seal off a pipeline or port within a DIN 11851 union system.
Key Features and Material
Function: The blank disc is inserted into the DIN male part, and the round slotted DIN nut is tightened to compress a D-shaped or P-section gasket against the disc's face. This creates a secure, leak-proof, and hygienic closure for any unused ports.
Material: The blank disc is made from high-grade 316 or 316L stainless steel. This ensures maximum corrosion resistance, as it is a "wetted" part that comes into direct contact with the product in food, beverage, and pharmaceutical applications.
Standard: Manufactured to the German standard DIN 11851.
Hygienic Design: The smooth surface finish and design that fits flush within the union help to eliminate crevices where bacteria could accumulate, supporting efficient Clean-In-Place (CIP) systems.
