Abstract
A pressure indicator is disclosed having a coupling body and an indicator member positioned within the coupling body. The coupling body has an open first end and an open second end, an inside surface and an outside surface extending from the open first end to the open second end. The inside surface surrounds a coupling body cavity. The outside surface is threaded adjacent to the second end. The coupling body is sized and dimensioned to be threaded into a bung hole of a static storage container. The indicator member is positioned within the coupling body cavity in a sealing relationship. The indicator member, biased to a first position, is movable from the first position within the coupling body cavity to a second position outside of the coupling body cavity responsive to the coupling body being exposed to a pressure within the static storage container above a predetermined pressure threshold.
