For all the HVAC techs and DIY plumbing folks out there, this Holigie eccentric flaring tool is seriously versatile. This heavy-duty tool can handle pipes from 4mm all the way up to 19mm (that's about 0.2 to 0.7 inches), covering pretty much every common size you'll encounter. What's really cool is it works with multiple materials - copper, aluminum, even thin-wall stainless steel pipes. The 45-degree cone gives you perfect flares every time, and the point access reaming means you can get into tight spaces without issues. The alloy steel construction makes this thing durable enough for professional use, but it's still manageable at about 2.3 kg (5.1 pounds). You get the main flaring tool plus a pipe clamp in the package, giving you everything you need for most flaring jobs. Whether you're working on condensers, heat exchangers, coolers, or boilers, this tool simplifies the whole process and actually makes flaring kind of enjoyable. The design reduces operator fatigue, which is huge when you're doing multiple flares in a day. Just a heads up - they might send either the new or old version randomly, but both work great. If you do any kind of pipe work regularly, this flaring tool will quickly become one of your most-reached-for tools.
