Viking Cylinders is the new North American brand for Hexagon Ragasco’s composite LPG cylinder, a product that has been in production since 2000. With more than 15 million cylinders sold around the world, Hexagon Ragasco is the undisputed leader in composite propane gas cylinders. Viking Cylinders previously sold in North America under the Ragasco name.
Are Viking Cylinders products safe?
Absolutely. Our cylinders are approved for use by the DOT and TC, and are actually far safer than steel propane gas tanks. Viking Cylinders propane tanks do not corrode or break down over time, and fire tests have proven they will not BLEVE. BLEVE is the technical abbreviation for Boiling Liquid Expanding Vapor Explosion. In layman’s terms this means our cylinder will not explode in a fire. Instead, the resin will burn off and the plastic liner and casing will melt. The LPG will then “breathe” through the cylinder wall and burn in a controlled manner. But don’t forget propane is highly flammable and should be handled carefully. Improper use can be dangerous.
Viking Cylinders propane tanks are produced by Hexagon Ragasco, the worldwide leader in composite LPG cylinders. (You can learn more about Hexagon Ragasco here.)

No. Only composite cylinders made by Lite Cylinder Company were recalled. Our products were not included. You can learn more about the recall here.
Aren't all composite cylinders basically the same?
Actually, no. While all composite cylinders use some type of composite material (hence the term “composite cylinders”), the product design, materials, manufacturing process, and testing procedures vary significantly from one company to another. Do not be led to believe that other companies make cylinders like ours. No other company has produced the same number of composite cylinders or maintained the outstanding safety record of Viking Cylinders.
What happens to a Viking Cylinders tank in a fire?
Ours are by far the safest propane gas cylinders available. Unlike a metal gas tank, a Viking Cylinders tank will not BLEVE in a fire. BLEVE is the technical abbreviation for Boiling Liquid Expanding Vapor Explosion. In layman’s terms this means the cylinder with not explode in a fire. Instead, the resin will burn off and the plastic liner and casing will melt. The LPG will then “breathe” through the cylinder wall and burn in a controlled manner.
What is the Viking Cylinders three-layer design?
Layer one is a blow-molded liner (HDPE) with an integrated boss for mounting the valve onto the cylinder. This creates a seamless gas barrier layer.
Layer two consists of composite fiber and resin wound around the seamless liner. This creates a vessel that has a tremendous capacity to withstand pressure. Our advanced curing process also ensures transparency, so you can see the level of gas remaining in the cylinder.
Layer three is the distinctively designed and extremely durable outer casing, which protects the pressure vessel and valve. Ergonomic handles allow for easy, comfortable lifting and are built for stacking.
Why is the cylinder translucent?
The translucency enables you to see the gas level through the wall of the cylinder, so you know exactly how much gas you have left. This eliminates the risk of running out of gas at an inopportune time. In addition, you’ll be able to tell if the cylinder was properly filled.
Are the cylinders UV resistant?
Yes. All of our materials are carefully selected to create an extremely durable product. One important feature is UV stability. UV additives are applied to the casing material to enhance UV resistance.
Will my cylinder rust or corrode over time?
Our cylinders are 100 percent noncorrosive. The selected construction materials ensure maximum chemical stability and resistance to concentrations of acids or solvents that may appear in the LPG or in the environment where the cylinders are stored or used. The cylinders don’t break down or rust, which means they don’t leave ugly stains on your deck, in your vehicle, on your boat, or anywhere else you choose to take them.
How do I maintain my cylinder?
Just clean the cylinder with soap and water. You can pressure wash them if desired, but sandblasting and painting is not necessary.
How much does a Viking Cylinders propane tank weigh?
The exact weight varies by size. On average, our cylinders are 50 percent lighter than steel propane gas tanks. Some sizes are more than 60 percent lighter than steel and 28 percent lighter than aluminum.
Is a fuel gage option available?
Our cylinders are translucent, so you can actually see the fuel level. This makes a gauge unnecessary.
Note: Did you know that most fuel gauges are unreliable? They read too full in warm temperatures and too empty in cold temperatures.
Will my cylinder come filled with propane?
We cannot ship a full cylinder, so yours will arrive empty. All you need to do is take the cylinder to your local propane distributor to be filled—the process is very simple and will even cost less than a traditional propane exchange.
How do Viking Cylinders products perform in colder climates?
Our cylinders are tested and approved down to -40°F (-40°C). However, the use of LPG in low temperatures is limited by the vaporization capability of the specific
How do Viking Cylinders products perform in desert climates?
Our cylinders are designed to withstand temperatures well above 149°F (65°C), and users who live in hot climates report that the design holds up well to regular use in steamy temperatures.
How do Viking Cylinders products perform in coastal or tropical climates?
One of the greatest benefits of the materials used in our cylinders is that they are unaffected by salt and humidity. The materials do not corrode, so the cylinders are well adapted for use in hot, humid, and saline environments.
What is the service life of a Viking Cylinders propane tank?
In the United States and Canada, our cylinders have a 15-year service life (15 years from the date of manufacture).
How do I requalify my cylinder?
Viking Cylinders propane tanks must be periodically requalified. We are the only composite LPG cylinder that can be requalified by visual inspection (a pressure test is not required). Requalification must be done by an authorized facility once every five years. You can learn more about requalification and find a requalifier here.
Note: Valves do NOT need to be replaced for requalification.
Do I need to replace the valve?
Periodic valve replacement is not required. Our cylinders use valves with M34 threads, sourced from Cavagna and Rotorex. These valves are different from those commonly found in steel cylinders and are not interchangeable. In the event a replacement valve is needed, it can be obtained through a reputable propane distribution company.
What is the warranty?
All of our cylinders come with a two-year warranty against manufacturing defects. If you think your cylinder has a problem, contact us. We are here to help!
