Flame King 20-lb Horizontal Propane Cylinder, White — Low-Profile Tank with Built-In Gauge

The Flame King YSN201HZL is a 20-pound horizontal steel propane cylinder designed for low-profile outdoor appliances like fire pits, fire tables, patio heaters, and RV connections.

If you need a compact, refillable propane cylinder that sits low and blends with outdoor furniture, this Flame King horizontal tank was built for that purpose. It arrives empty and pre-purged, fitted with a Type 1 Overflow Protection Device (OPD) valve and a built-in gauge so you can refill and use it right away. Powder-coated steel gives it weather resistance and a clean white finish to match many patio and RV setups.

How does this tank fit into fire tables and outdoor heaters?

The low-profile horizontal shape lets the tank hide neatly under or inside many fire table cabinets and heater bases. Its collar handle design makes installation and removal easier without sharp edges to snag surfaces. Because it’s DOT approved and hydrostatically tested, it meets standard safety and refill requirements for consumer outdoor equipment.

• 20-pound capacity for longer run times than small disposable cylinders
• Horizontal form factor for discreet placement in furniture cavities
• Collar handle for safe handling and quick swaps
