ABSTRACT:
An automatic locking pressure regulator or valve for a fuel tank. The regulator or valve includes locking means which prevent loosening of the regulator or valve from a standard fuel cylinder valve outlet connection. In a preferred embodiment of the present invention, the locking mechanism is coupled to the base of the regulator or valve, and protrudes into the threads on the standard fitting on the fuel cylinder to prevent one-way rotation of the pressure regulator or valve.
