I have been in the HVaC field for 15 years, I owned a HFreight flaring tool and a nice yellow jacket one. the yellow jacket was garbage from day one. caused a lot of problems. This tool is awsome, it has an automatic stop release so you cant over tighten, the pipe stop i figured i would never need but turns out it is convenient. I always lube the flaring tool with a single drop of zoom spout so it doesnt gall, and fastest easiest flares and most perfect flares i have achieved this fast.the handle is large so your not struggling toward the end, little physical force.its very solid. I believe this will last close to when i retire. I will buy this for my next one.Just to clarify i pulled my scrap 3/4,1/2,and 3/8 and flared all of those before posting this.
