DIN 11864-3 & DIN 11853-3 Aseptic Unions

This range of aseptic fittings has been developed by the German hygienic industry to meet the exacting needs of the pharmaceutical, food and fine chemical industries. 

Three designs of pipe fittings have been tailored to accept 2 different types of aseptic seals that effect a smooth interface within the pipe work whilst simultaneously achieving a metal to metal seat behind the joint.

The seal sections used are referenced as “Form A” and “Form B” and both have distinctive profiles that are easily recognised.  Form A is an O Ring Joint whilst Form B is a 2-part Square section seal with a secondary internal diamond section. (Form B is not commercially available).

The Type 3 design is based on the 3A Clamp union and uses the flange diameters common to the Metric DIN 32676 Standard.   

Available with optional lengths to suit Orbital and Manual Welding, these unions have been designed to match tube and pipe specifications including DIN 11850 / 11866; ASME BPE 2022 and BS 4825 Part 1 and also the DIN11866-B / ISO 1127 Standard for schedule pipe.
