Product Overview
The Flame King YSN5LB‑GAUGE is a 12.8‑inch high, 8.1‑inch square portable propane tank designed for the serious outdoor adventurer. Crafted from high‑grade welded alloy steel, the cylinder is powder‑coated to protect against rust and the harsh elements of backcountry use. Weighing just 9 pounds, it balances durability with manageable weight, making it easy to carry in a backpack or attach to the brand’s dedicated propane backpack system. A built‑in gas meter gauge provides real‑time fuel level readings, while an overfill prevention device (OPD) valve safeguards against accidental over‑filling. Certified by DOT and Transport Canada, this tank meets rigorous safety standards for both U.S. and Canadian transport.
Usage

The Flame King tank excels in a variety of outdoor scenarios. Whether you are setting up a camp stove for a weekend trek, powering a portable heater during ice fishing, or running a small grill at a remote picnic, the tank delivers consistent, clean‑burning propane. Its compact dimensions fit comfortably in standard propane backpacks, and the easy‑hold collar allows one‑handed placement on a tripod or stove. The built‑in gauge eliminates guesswork, so you can plan refills before you run out, extending your time on the trail. The OPD valve adds an extra layer of safety when refilling at a gas station or using a portable refill kit.
Why Choose Us
Flame King’s reputation for rugged outdoor equipment is backed by meticulous engineering. The alloy steel shell is welded, not bolted, providing superior structural integrity that resists dents and punctures. Powder coating not only gives a sleek finish but also creates a barrier against moisture and corrosion, extending the tank’s service life. Each unit undergoes X‑ray and hydrostatic testing, ensuring it can safely contain up to 20 pounds of LPG under pressure. DOT and Transport Canada certifications mean you can transport the tank across borders without additional paperwork. The inclusion of a built‑in gauge and OPD valve, features often sold as accessories, are standard on this model, delivering true value.
