Abstract
A separation end cap adapted for connecting adjacent separation elements is provided. The end cap may be located at the distal ends of a separation element and is adapted for connection with a permeate tube located within the separation element. In one embodiment the end cap includes an inner hub for receiving an O-ring to seal against an inner hub of an end cap on an adjacent separation element. The inner hub of the end cap may be spin-welded to the outer surface of the permeate tube. A locking structure on an outer hub of the end cap co-acts with a locking structure on an end cap of an adjacent separation element to releaseably lock the end caps and, therefore, adjacent separation elements. The locking structure preferably provides a predetermined axial force on the O-ring to seal the connection between permeate tubes of adjacent separation elements. The locking structure may also provide audible and/or visual feedback that the locking of adjacent end caps has been achieved
