## Description

desertcart.com: Flame King YSN401 Steel Propane Tank Cylinder With Overflow Protection Device Valve, 40 Lb, White : Tools & Home Improvement

Review: Good tank - Arrived in good shape. A bit heavy once filled, but still able to maneuver it as needed. Bought these for use with my portable tri-fuel generator. Propane lasts forever whereas gasoline goes bad over time so I decided this was a good investment to store the propane until it's needed.
Review: Well made - Well made

## Features

### ⭐⭐⭐⭐⭐ Heavy-Duty Tank That Does Its Job
*by E***N on December 11, 2025*

The Flame King 40-lb tank feels solid, filled easily, and the valve works smoothly. No leaks, no issues—just heavier to move around than smaller cylinders. So far it’s performed exactly the way I expected.
