Aseptic Union Male Series A DIN 11864 DIN

Key Features

• DIN 11864-1 Form A Compliance – Manufactured to the German aseptic standard, ensuring compatibility with DIN 11864 series components

• Dead-Space-Free Sealing – O-ring sits in a precision-turned groove with metallic centering, eliminating crevices where product residues could accumulate

• Orbital Welding Ready – Extended welding ends support both orbital and manual welding for seamless integration into hygienic piping systems

• High-Grade Stainless Steel Construction – Available in 316L (1.4404/1.4435) with delta ferrite content < 1% for optimal weldability and corrosion resistance

• Superior Surface Finish – Product-contact surfaces precision-turned to Ra < 0.8 µm (Hygiene Class H3), meeting the highest hygienic standards

• Wide Size Range – Available from DN10 to DN150 to suit diverse system requirements

• High Temperature & Pressure Rating – Suitable for sterilization temperatures up to 150°C; pressure rated up to 40 bar depending on size

Key Advantages

• Maximum Process Safety – Dead-space-free design minimizes contamination risks and ensures sterile operation in critical applications

• Superior Cleanability – Optimized for CIP (Clean-In-Place) and SIP (Sterilize-In-Place) processes, reducing downtime and enhancing productivity

• Reliable Sealing Performance – O-ring-based sealing system with FDA and USP Class VI-compliant elastomers ensures leak-free, hygienic operation

• Versatile Applications – Suitable for pharmaceutical (WFI, pure steam, API synthesis), biotech (cell culture, fermentation), food & beverage (dairy, juice, beer), and fine chemical industries

• Long Service Life – Premium stainless steel construction with 3A certification delivers exceptional durability under repeated sterilization cycles

• Interchangeable Design – Standard DIN 11864 configuration ensures seamless compatibility with existing aseptic piping systems

How It Works

The DIN 11864 Male Union operates as part of a three-component aseptic screwed connection system:

1. Assembly – The male union is welded to the tubing end (via orbital or manual welding)

2. Sealing – An O-ring (EPDM, VMQ, or FKM) is placed in the precision groove of the male part

3. Connection – The liner (female part) is brought into position against the male union

4. Securing – The union nut is threaded over the connection, compressing the O-ring to form a dead-space-free, hygienic seal

5. Centering – Metallic centering ensures precise alignment of both components

This design provides a detachable yet secure connection that maintains sterile integrity while allowing for easy disassembly during maintenance or process changes.
