A disposable tamperproof shipping valve for containers of fluids, especially those under pressure. The valve of unitary, one-piece construction incorporates a tamperproof, hermetic seal and includes a means for opening a check valve in an external dispenser for fluid flow control. It is amenable to ready insertion into the filling opening of a fluid shipping container. There, the valve remains sealed until the sealing ring is broken for fluid dispensing and consumption or use.
