DIN11864 O-Rings
Aseptic DIN11864 O-rings – according to DIN 11864 (form A) – are commonly used in DIN 11866 pipe couplings.
The coupling comprises of a male and female ferrule (which include an O-ring groove) and a clamping device. This aseptic pipe connection is widely used in hygienic processing applications in industries such as:
- Food, dairy and water
- Pharmaceutical
- Biotechnology
PPE manufactures various hygienic connectors to fit aseptic pipe couplings including; HyClamp™ sanitary gaskets, IDF gaskets, RJT O-rings, DIN 11851 D-seals and SMS seals.
