Filter Cartridges which are compatible with Filter Housings sold by Boshart.

The majority of filter housings and filter cartridges used in the water industry are double open ended (DOE) cartridges which are designed to seal at both the top and bottom by compression against the round knife type seat seal in the filter head (top) and in the filter bowl (bottom) this seal can be directly against the filter media in the case of a string wound or spun poly depth cartridge, or against a plasticised end cap on PAC type carbon and or pleated type filter cartridges, other types such as cannister type GAC granular carbon or carbon block cartridges will seal against rubber gaskets incorporated on the ends of the cartridges.
