I was on the hunt for a reliable propane tank and decided to give this one a go, and I'm so glad I did! Right off the bat, the OPD (Overfill Prevention Device) Valve instilled confidence in terms of safety during both use and refilling processes. This feature alone, which helps to prevent overfilling, adds an extra layer of security that’s incredibly reassuring. The white exterior has proven to be resilient against weather conditions and hasn’t shown signs of wear or rust even though it's stored outside. Refilling it has been a breeze, and I've found that it holds the propane reliably without any concerning leaks or issues. The 40-pound capacity has been adequate for our usage, ensuring we’re not constantly needing to refill it, which has been especially convenient. Overall, the Flame King Propane Tank is sturdy, reliable, and gives me peace of mind knowing that safety is prioritized with the OPD Valve. I’m very pleased with this purchase and would recommend it to anyone in need of a high-quality, dependable propane tank." Review: Well made - I have a dual-fuel 13kW generator that can operate on gasoline or propane, and I want to always have fuel on hand to run it in case of an emergency. I'm not interested in storing gasoline long-term, but propane is very easy to store. I've picked up a couple of these propane tanks and I have them filled at Tractor Supply, and then I store them outside on the porch. They're solidly made with good, tight valves that come with a dust cover for protection when not in use. They can be a little awkward to lift or move around when they're full if you're not accustomed to that, but i have a couple of them so I'm used to it. With a tank this size, my generator can run most all day at half load. I'll probably pick up a couple more of these. ## Features - EMPTY TANK: Pre-purged vacuum ready for filling with propane; built from high-grade, welded steel and powder coated for rust prevention - OVERFILL PREVENTION DEVICE: Comes with an OPD valve to prevent overfilling; required by law in most States, if your tank doesn't have this, most places won't fill it! - SAFETY: X-ray and hydrostatic tested and DOT and Transport Canada certified so you can be sure to transport safely both in the US and CA - SUIT YOUR NEEDS: With a standard-size connection valve, this large 40LB tank will connect as easily as smaller tanks, and work with RVs or trailers, propane tank attachable heaters, and other accessories. - LEADING THE INDUSTRY: Flame King, a leader in propane storage solutions, prides itself on making the highest quality, premium, refillable propane tanks on the market.
