A valve (20) for an inflatable product. One valve includes a cap (56) that provides a double seal (58, 60) . An inner seal (58) closes an opening (66) for the valve (20) . The inner seal (58) and the opening (66) are mounted in a chamber, and the chamber is closed by a second, outer seal (60) that provides a backup in case of failure of the inner seal (58) . A flapper valve (22) may be used as another seal. Another embodiment of a valve (120) includes a rigid cap (124) . Still another embodiment of a valve (220) includes a plug (232) that is attached to a valve opening.
