Keep your piece of mind and your nitrous safe at the same time. Used to release the possible over pressure due to a rise in ambient temperature or the overuse of a bottle blanket/heater. Nitrous pressure increases as the bottle temperature increases, for example a bottle kept at 60°F has a bottle pressure of 675 psi. Increase the bottle temperature to 70°F and bottle pressure increases to 760 psi. At 97° nitrous pressure is an enormous 1069 psi.
