Abstract
The present invention sets forth an adapter for filter cartridges and a mating cartridge which provides sealing means between the cartridge and the adapter and sealing means between the adapter and a filter head to which it is to be installed, and means for installing the adapter on a cartridge and for installing the adapter in the filter head with an aligning and locking means that ensures that all parts are appropriately positioned for proper function and at the same time will prevent physical disengagement and/or a break in the flow path from the cartridge to the filter head when the cartridge and adapter are properly installed in the filter head.
