DIN11851 SEAL

Key Features

• Dead-Space-Free Sealing – Precision-fit O-ring sits in a specially turned groove, eliminating crevices where product residues could accumulate and bacteria could grow
  

• DIN 11864 Form A Compliance – Manufactured to strict DIN 11864 dimensional specifications, ensuring perfect compatibility with DIN 11866 tubing systems
  

• Multiple Material Options – Available in EPDM, FKM (FPM), VMQ (Silicone), NBR, HNBR, and FFKM to suit diverse media and temperature requirements

• Wide Size Range – Covers DN10 to DN100 (Series A), with additional sizes available for Series B and Series C tubing standards-

• FDA Compliant Materials – All elastomer materials meet FDA 21 CFR 177.2600 requirements for food contact applications

Key Advantages

• Superior Hygiene – Dead-space-free design eliminates bacterial breeding grounds, ensuring aseptic integrity in critical processing environments-
  

• Versatile Compatibility – Suitable for all three DIN 11864 connection types (screwed, flange, and clamp), offering one sealing solution for multiple system configurations-
  

• Exceptional Chemical Resistance – Material options available for aggressive media, abrasive products, and high-temperature processes-
  

• Regulatory Compliance – Full compliance with FDA, 3-A Sanitary Standards (18-03), and USP Class VI requirements

How It Works

The DIN 11864 O-Ring operates on a proven sealing principle:

1. Placement – The O-ring is inserted into the precision-machined groove on the male ferrule (or flange/liner component)-

2. Assembly – The male and female components are brought together, with the O-ring positioned between the sealing faces-
   

3. Compression – As the connection is tightened (via threads, bolts, or clamps), the O-ring is compressed between the two metal surfaces-

4. Sealing – The compressed elastomer fills all microscopic gaps between the metal faces, creating a leak-proof, crevice-free seal-

5. Metal-to-Metal Stop – The design achieves a metal-to-metal seat behind the joint, preventing over-compression and ensuring consistent seal performance-
   

6. Service – The seal can be easily inspected and replaced during routine maintenance without special tools

This design provides a reliable, hygienic seal that prevents product contamination while allowing for easy disassembly and maintenance.
