DIN 11864-3 & DIN 11853-3 Form A Aseptic Clamp Fittings – European Stainless Steel (DN10–DN100) or 1/2"ISO21.3 -3"ISO88.9
High‑performance aseptic clamp fittings for pharmaceutical & chemical industries
The German standards DIN 11864‑3 and DIN 11853‑3 define stainless steel clamp fittings for aseptic and hygienic applications. Type 3 refers specifically to aseptic clamp connections (tri‑clamp compatible), while Form A denotes an integral O‑ring groove (O‑section) machined directly into the ferrule. The seal is positioned between the male and female ferrules, ensuring a dead‑leg‑free, cleanable joint.
These fittings are widely used in:
Pharmaceutical sterile processing (WFI, SIP/CIP skids)
Biotechnology & fermentation
Chemical industry with high purity requirements
Aseptic food and cosmetic lines
