DIN Union

A "DIN union" is a sanitary fitting designed for piping systems, particularly in the food and beverage industry, that complies with the German DIN standard. These fittings are manufactured according to the specifications established by the Deutsches Institut für Normung (German Institute for Standardization).

Key Features of DIN Unions

1. Standard Compliance
DIN unions adhere to the DIN 11851 standard, which specifies the design and dimensions of stainless steel screw pipe connections used in sanitary applications.

2. Applications
They are commonly utilized in industries such as brewing, winemaking, and dairy production, where hygienic connections are essential. These unions are valued for their ease of disassembly and cleaning, making them ideal for environments with strict sanitary requirements.

3. Components
A typical DIN union includes:

• A male component with a round slotted nut
• A female component with a liner
• An EPDM (ethylene propylene diene monomer) gasket for secure sealing

4. Distinguishing Features
Compared to other sanitary unions, such as RJT or BSM, DIN unions have unique thread profiles and dimensions that differentiate them while maintaining high performance in sanitary environments.
