DIN 11864 O-rings
Aseptic 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:
PPE offers DIN 11864 O-rings in a range of elastomer materials to provide the optimum performance in any application. The range includes EPDM, VMQ (silicone), FKM, and FFKM (Perlast® perfluoroelastomers). See the full material range in the drop-down section below.
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.
