Recently had a friend recommend the Z-pipe insert for zippo lighters. If you are like me you don't like the taste of zippo lighter fluid and prefer a butane lighter. I have tried other zippo type lighter inserts and haven't yet found one that really lasts and has a deep reaching flame, until now. The z-pipe fits a standard zippo lighter and they make 2 models, a torch and a pipe lighter. I have the pipe lighter for obvious reasons. It fist snugly, has a metal construction, and holds a good deal of fluid. The flame level was a bit low for my taste at first even turned all the way up because it has a black tab that keeps you from turning it higher, but that will easily pop off with a knife tip. I took that piece off, adjusted the flame to where I wanted it, and popped it back on. Now I have a great long lasting lighter that reaches deep into even my big pipes and I also get to use one of my cool sentimental zippos. I would highly recommend these, and they are less than $15.
