Double Open End (DOE) Cartridge Fittings

Your Subtitle Goes Here
Where filter cartridges that have both ends open, a seal needs to make to the housing to close one end and direct flow through the other. The sealing mechanism typically uses knife edges on both ends, with one end combined with a blanking cap and the other end featuring a hole leading to the clean chamber of the housing.

Single Open End (SOE) Cartridge Fittings

Designed with one end of the cartridge blocked by a blanking end cap, while the other end remains open with an attached end cap equipped with built-in ‘O’ rings. This configuration provides a highly efficient and reliable seal compared to the Double Open End (DOE) configuration. In addition to the improved sealing method, SOE cartridges offer easier and more reliable installation into filter housings and have fewer loose internal components, facilitating cleaning and maintenance.
