A valve assembly for use with a self-sealing collapsible storage bag, the valve assembly having a first portion comprising a housing that has a sealin g surface and contains a valve mechanism. A second portion has a sealing surfa ce that is configured to mate with the sealing surface of the first portion. A snap mechanism is configured to allow the first and second portions to be snapped together with their respective sealing surfaces facing each other to form a substantially airtight seal. In operation, the first and second portions are positioned on opposing sides of a panel of a plastic storage ba g, and snapped together so as to sandwich the panel between the first and secon d portions of the valve assembly. The plastic bag is pierced in the area of th e valve assembly either during installation of the valve assembly, or later by insertion of a nozzle. Gas or fluid such as air may be selectively removed from or added to the interior of the storage bag through the valve mechanism .
