Vector Formula 14 filtered 14x premium butane gas is highly recommended for all high performance Vector and other gas torches and lighters. This ultra-clean butane is refined up to 14 times, while most other butane are refined 1 to 3 times. Jet torch and turbo lighters require ultra pure Vector gas to produce highly efficient jet flames. Do not use other cheap brands as they will clog the internal burner cylinder and affect the performance of the lighter. Vector butane is at the top of the butane class providing the best quality of butane available.
