Cartridge filter end caps: DOE, SOE, 222 and 226 explained

Cartridge filters have two main end designs: double open end (DOE) and single open end (SOE). A DOE cartridge seals by compressing its flat gaskets, while an SOE cartridge seals by seating its 215, 222 or 226 O-ring adapter in the housing socket.
