DIN 11864-3 Aseptic Clamp Unions

Application

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

Three designs of pipe fittings have been tailored to accept 2 different styles 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 seal with a secondary internal diamond section.
