PFA-lined milk pipe fitting with flanged connection
EN 1092-1 B1

Our PFA-lined milk pipe fitting, compliant with DIN 11851, combines proven hygiene technology with the highest level of chemical resistance. The flange connection, compliant with EN 1092-1 Form B1, enables a secure, standards-compliant connection to piping systems in plant engineering—ideal for demanding processes in the chemical, pharmaceutical, food, and beverage industries.

The PFA lining reliably protects all surfaces in contact with the medium from corrosive and aggressive substances while providing a smooth, non-stick surface that prevents deposits and simplifies cleaning. This makes this assembly perfectly suited for corrosive, high-purity, or hygiene-critical applications.

Key Features:

• Corrosion protection via PFA lining – maximum 
   resistance to acids, alkalis, and solvents
• Hygienic design per DIN 11851 – easy to clean,
   CIP/SIP-compatible
• Flange connection per EN 1092-1 B1 – easy integration into 
   standardized piping or equipment connections
• Long-term leak-tightness and mechanical stability – 
   even under thermal and chemical stress
• Versatile application – from process connections in the  
   pharmaceutical industry to aggressive media in the 
   chemical industry
• FDA-compliant in PFA and PFA-AS versions
