My tools for beer...
1. My DIY Beer line cleaner for my Ball Lock lines... nothing makes beer taste better than clean beer lines.
2. Teflon Tape... Leak Free CO2 stops the surprise of being out of CO2 at the wrong time.If it has threads, it get Teflon Tape.
3. My Oetiker Clamp Crimp tool. Hassle free non leaking Beer lines and CO2 lines are a God send. Worm clamps or those little plastic clamps are just not good enough to be worry free.
4. 6 in 1 Combination Beer Mechanics Wrench. Only one tool to reach for when working on my beer system the PER (LICK/FECT) tool.
These are tools/items, pretty much only used for BEER that should be in every Beer guys arsenal. As this thread is in the HOME BREWING BEER>DIY Thread I'm sticking to BEER tools used all the time in the drinking (most important part) of beer.
Hell yeah. I'm looking forward to the day that I can say that these are my most useful tools.
