Abstract

A connection between a fluid filter and a head is described that permits quick connection/disconnection between the two without requiring disconnection of fluid lines from the head. The head includes a lock to connect inlet and outlet fluid lines to a fluid filter using a non-threaded attachment method. The lock that retains the head to the fluid filter is flexible to allow for connection and disconnection. The head has fluid inlet and outlet ports to which fluid lines attach to flow unfiltered fluid into and filtered fluid out of the fluid filter when the head is connected to the fluid filter. The head closes the fluid filter, which has a protrusion with adjacent passageways that guide and separate unfiltered from filtered fluid.
