It provides dual protection: the frangible stem can be broken manually to quickly close the tank’s emergency and vapor recovery valves, and a built‑in fusible element melts automatically in a fire to relieve line pressure and close those same valves. It is a single‑use safety component designed to meet DOT 49 CFR §178.345‑11 and CSA B620 requirements.
