LP Propane Tank Cylinder 30 lb. Filled

Overall length: 17.56-inch; Tank height: 13.62-inch; Tank Diameter: 12.16-inch; Base Diameter: 8.0-inch. Manchester Tank Cylinders conform to DOT and NFPA 58 specifications, including OPD (overfill prevention device) requirements for 5-pound to 40-pound cylinders. 

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.
