  • Nice tank but....
Pattern Name: Tank Cylinder
Amazon sells Flame Kings 30 lb tank which is a better value!!! 2 of these tanks hold 5 more gallons of propane than the 40lb tank, but cost virtually the same. Both size tanks are very well made and are light enough to carry even when full. The tanks come with an OPD valve (Overfill Prevention Device) which is a great safety feature. The 40lb tank, as well as the 30lb tank, give me the ability to not have to store and rotate gasoline, as I no longer have to worry if my gas is fresh. This is my 2nd Flame King tank, my 1st being a 100 gallon. I look forward to many years of reliable use from my 40lb tank as I've gotten from my 100 gallon tank. ... show more

  • My go to tank for generator use
Pattern Name: Tank Cylinder
My experience with the Flame King YSN401b 40 Pound Steel Propane Tank has been nothing but positive. 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." ... show more

  • Solid Tank
Pattern Name: Tank Cylinder
Bought this for a propane powered generator. The tank arrived well packaged and intact. It seems well made and sturdy. Filled it about two weeks ago. No signs of leakage. Also purchased the base to help stabilize it and prevent it from being knocked over while in use.

  • Prepper item
Pattern Name: Tank Cylinder
The bottle is pretty tall, and to fill then transport most places want you to have it properly secured in a bed of a truck or to the walls of a van. I was going to move in a trailer but that darn trailer bounced around too much when I hauled a cement mixer, and I am not going to make that mistake again. I plan on buying another and maybe a smaller tank, regulators and hoses to move gas between tanks as needed too. ... show more
