This Propane Cylinder is a hassle-free solution for your BBQ needs. Pre-purged and vacuum-filled at the factory, this 5-pound tank eliminates the need for purging. Made from high-grade steel with a powder-coated finish for rust prevention, it's built to last. For safety, the built-in overfill protection device (OPD) valve stops gas flow when the cylinder is full. Ideal for many summers of grilling enjoyment.
