Flame King Liquid Propane Gas (LPG) Fuel Tank

Flame King LPG Fuel Tanks: Built for Safety, Engineered to Last

When it comes to storing and transporting liquid propane gas, few names carry the same weight as Flame King. The brand has built its reputation as a propane storage specialist, and nowhere is that expertise more evident than in its lineup of LPG fuel tanks. These aren't generic cylinders — they're purpose-engineered vessels designed to meet the rigorous demands of RV owners, outdoor enthusiasts, tradespeople, and homeowners alike.

Steel Construction and Industry-Leading Certifications

Every Flame King LPG fuel tank starts with a foundation of high-grade welded steel. Tanks are powder-coated for corrosion and rust resistance, ensuring they hold up to the outdoor environments they're built for. Critically, all portable cylinders are manufactured to Department of Transportation (DOT) or Transport Canada (TC) specifications, and the facilities producing them operate under a Quality Management System certified to ISO 9002 requirements. Select tanks also carry ASME certification, making them suitable for a broader range of stationary and vehicle-mounted applications. Each tank is x-ray and hydrostatically tested before it ever leaves the factory.

Pre-Purged and Ready to Fill

One of the most practical advantages of Flame King LPG tanks is that they arrive pre-purged and vacuum-ready for filling — saving owners the time, cost, and hassle of purging a new tank themselves. Tanks are sold empty in compliance with shipping safety regulations and can be filled at any licensed propane dealer or refill station.

Safety Features That Matter

Flame King tanks in the 4–40 lb range include a mandatory OPD (Overfill Protection Device) valve, a critical safety mechanism required by U.S. law for portable cylinders in this size range. Many models in the lineup also feature a built-in fuel gauge, giving users accurate at-a-glance propane level readings so there are no unwelcome surprises mid-cook or mid-trip. Ergonomic collar handles make lifting and transporting even larger cylinders more manageable.

The Right Tank for Your Application

Flame King's LPG tank lineup is designed to cover a wide spectrum of real-world use cases. Whether you need a compact cylinder for a portable grill, a mid-size tank for an RV or trailer heating system, or a larger vessel for extended outdoor work, the standard-size connection valve ensures compatibility with RVs, propane-attachable heaters, and a wide range of other accessories.
