Green isn’t good enough; blue is better. For years, propane has come in two main forms: large refillable cylinders, which are affordable to fill at service stations but too bulky for outdoor adventures, or small green bottles, which are convenient but create hazardous waste in landfills and nature. While some attempt to refill these small bottles at home, the process is often unsafe, inconvenient, and sometimes even illegal. The TapRack™ gives you the best of both worlds: a small, easy-to-carry package that is refillable at service stations wherever you go. No special adapters or tools are required.
