Gasket for the food and beverage industry DIN Union

Product Overview
DIN Union refers to fittings compliant with the DIN 11851 standard. DIN Union Gaskets are specifically designed for DIN fittings and are commonly used on pumps, processing equipment and machines that follow DIN 11851. The DIN union features a conical weld liner that sits slightly inside the male part on top of the seal to ensure correct alignment when tightened.
