Ridgid makes quality stuff so no issues there, but this type of flaring tool can be a PITA to use in some places, and a certain amount of skill is needed to get good flares. The double-flare die for brake lines can be a bit fragile, I've broken several of them. More money, but as close to idiot-proof as you can get.... https://www.amazon.com/MASTERCOOL-72485-PRC-Universal-Hydraulic- Transmission/dp/B06WD86RLH/ref=psdc_15707271_t1_B01NCYKQSN Worth every nickel to me, and I've loaned this out a few times and gotten nothing but rave reviews back. Eastwood makes a cheaper similar unit but theirs is bench-top unit only, the hydraulic can be used on the vehicle in some cases if need be.
I have a Rigid 377 that I use on 37 degree AN flares, I find it works great and has a ratching feature that as soon as you form the flare it stops from going too far, I use mostly 1/4" 304 SS tubing with back up sleeves so no double flare capacity. I have flare the new style copper/ steel tubing and it works great. I believe I bought it from Home Depot for around $115
I have a 45 and 37 degree , Rigid flare tools . Mine were made years ago in the good ole US of A . Never one is sure to date .
this tool has the 3/16" fraction stamped into the unit but they never milled the half holes on each side... it says 3/16" but... . no worries, they stamped the fractions a certain distance apart... but milled the gripping slots closer together as the holes got smaller... 1/4" is stamped beside the 3/16" hole... 3/16" stamping isn't beside any hole... gonna be fine...
