Experience the perfect propane tank duo with this Flame King refillable cylinder bundle. The set includes a 16.4 oz green tank and a 14.1 oz blue welding cylinder, both designed for safe and legal refilling. The green tank offers versatile compatibility with standard 1LB propane appliances, while the blue cylinder's tall, skinny design is specifically engineered for better grip during precision tasks like welding, soldering, and culinary torching applications. Both tanks feature high-grade steel construction and come complete with caps and 2mm (5/64") Allen keys. The blue cylinder's specialized shape makes it ideal for detailed work such as caramelizing sugar on creme brulees, melting cheese, or precision welding, while the green tank serves as your go-to for general propane applications. This eco-friendly bundle helps reduce environmental waste by providing a reusable alternative to disposable tanks. As the only DOT-certified refillable and transportable 1LB tanks on the market, these cylinders offer a safe, legal, and cost-effective solution for your propane needs. Both tanks can be easily refilled in your backyard, making them a convenient and sustainable choice for both professional and household use.
