LP Cylinder Propane Tank 40 lb. Filled

Filled 40 lb. Cylinder propane tank that conforms to DOT and NFPA 58 specifications, including an overfill prevention device. Also sold empty.

Note: When transporting Liquefied Petroleum (LP) tanks (propane cylinders), keeping them strictly in the upright (vertical) position is critical for safety and proper mechanical function. The tank features a built-in spring-loaded safety pressure relief valve designed to sit in the vapor space at the very top of the cylinder. When the tank is upright, any vented gas escapes as vapor. If the tank is laid on its side, liquid propane can cover or reach the relief valve, causing dangerous pressure spikes.
