DIN NUT

DIN NUT

The DIN hygienic nut is a round, slotted nut made from Grade 304 stainless steel that is a core component of the DIN 11851 sanitary pipe union.

It is specifically designed to allow for the rapid assembly and disassembly of process lines using a specialized C-spanner or hook spanner.

Key Features and Specifications

  • Function: The nut threads onto the external thread of the DIN male part. When tightened, it compresses a D-shaped or P-section gasket between the male and the liner to create a high-pressure, hygienic, and leak-proof seal.
  • Material: The nut itself is typically made from 304 stainless steel for durability and general corrosion resistance, as it is not a "wetted" part (it does not contact the product). The internal components (male and liner) are made from the more resistant 316 grade.
  • Standard: Manufactured according to the German standard DIN 11851.
  • Design: The round, slotted design provides a secure grip for the appropriate spanner, ensuring a strong mechanical connection.
  • Compatibility: Available in both metric (DN 10 to DN 150) and imperial sizes (1" to 4") to match existing pipework standards.
