ABSTRACT:
Sealing means for a reverse osmosis system includes an approximately cylindrical body (103) open at one end and including an outwardly stepped portion (109) at its open end which receives a cylindrical rim (121) of a cover (107). An O-ring seal (123) is seated in an annular groove (125) of the cylindrical rim and includes an outwardly projecting annular tongue (123B) which engages and seals against the inner surface of the stepped portion (109) of the cylindrical body (103). Annular filter element (105) is positioned in an upright attitude in the cylindrical body (103) and fluid moves through inlet opening (31) of the cover (107), then downwardly into the outer portion of the cylindrical body, then through the annular filter, then upwardly through the cover to an outlet (135). The liquid then moves through the other elements of the reverse osmosis system, including a boiler (29) and condenser (33), to storage tank (35).
