Flame King 454 g Refillable Propane Cylinders 4-Pack, 485 ml Steel Tanks with DOT Certification

Flame King 1LB empty propane cylinders are reusable, DOT-certified 16.4 oz tanks designed to be legally and safely refilled for camping, grilling, and outdoor gear.

If you’re tired of buying disposable 1 lb propane canisters, this four-pack from Flame King offers a long-lasting alternative built from high-grade steel with powder-coat protection and certified testing. Each cylinder uses Flame King’s patented refill valve, meets DOT and TC standards, and is UL1769 listed. They’re made to work with the same appliances that accept single-use canisters—so you can refill at home or at a refill station and reduce both cost and waste over time.

How do these refillable 1 lb propane cylinders work with my outdoor appliances?

The Flame King 1LB tanks are sized and threaded to fit appliances that accept standard 1 lb disposable cylinders, including many stoves, heaters, and grills. They replace disposable bottles without adapter changes and connect the same way for convenience and compatibility.

• Standard 1 lb cylinder dimensions and valve interface for common appliances
• Patented Flame King valve designed for safe refilling and transport
• Works with portable stoves, camp grills, and small heaters that accept 1 lb canisters
• Sold in a four-pack for multiple devices or spares

What safety certifications and testing do these tanks have?

Each Flame King tank is DOT- and TC-certified and undergoes X-ray and hydrostatic testing to ensure structural integrity. The tanks are designed to be legally refilled and transported, unlike single-use disposable canisters that are not intended for refilling.

• DOT-compliant design and transport approval
• X-ray and hydrostatic pressure testing during manufacture
• UL1769 listing for portable cylinders
• 12-year certified service life in the U.S. (10 years in Canada)
