<p>A separation end cap (34) adapted for connecting adjacent separation elements (12) is provided. The end cap (34) may be located at the distal ends of a separation element (12) and is adapted for connection with a permeate tube (18) located within the separation element (12). In one embodiment the end cap (34) includes an inner hub (36) for receiving an O-ring to seal against an inner hub (36) of an end cap on an adjacent separation element (12). The inner hub of the end cap may be spin-welded to the outer surface of the permeate tube (18). A locking structure (52) on an outer hub (48) of the end cap co-acts with a locking structure (52) on an end cap (34) of an adjacent separation element (12) to releaseably lock the end caps and, therefore, adjacent separation elements. The locking structure (52) preferable provides a predetermined axial force on the O-ring (34) to seal the connection between permeate tubes (18) of adjacent separation elements (12). The locking structure may also provide audible and/or visual feedback that the locking of adjacent end caps has been achieved.</p> |
