DOUBLE CHEN HVAC Swaging Tools Kit Hydraulic Copper Pipe Tube Expander Tool 3/8, 1/2, 5/8, 3/4,7/8,1,1-1/8 Inch

Haven't gotten a chance to use it yet but it feels solid like the more expensive brands. Tested and working right out of the box. Comes with a hard shell case, a copper cutter, and a deburring tool! We'll worth the money. Everything fits well in the box too. Can't wait to use it! Paint finish was nice too 👌 very easy to use.

I purchased this tool to repair chillers with metric tubing. I can only buy imperial tubing and repair parts. I use this tool to make everything fit together. For what I save purchasing copper fitting I could buy one of these for every job. This has been a good tool without any problems. The hydraulic reservoir is a small plastic or rubbery tube inside the handle. I don't know how long until this leaks or dries up and cracked. DO NOT REFILL WITH A SYNTHETIC HYDRAULIC OIL. Most synthetic oils will eventually harm most plastic parts. Overall a good tool at a fair price.The only thing that would make it better would be to include a 1/4 inch expander. You can buy one for about $35 on Amazon and there is plenty of extra room in the case for extra expanders and accessories.

Works fine on soft copper excellent value for the money

Overall the tool works great. It will swage out the copper with no issue and so long as you anneal plumbing copper it will do the trick. The swages are slightly oversized leaving a bit of wiggle in the joints. It can be filled and it does work fine it just doesn’t allow for as good of capillary action. 3/8 will split without annealing first.

Honestly I held out for a long time buying a tool like this, but once I picked it up (and yes this one is a cheaper version of the "name Brand" ones) and used it a couple times, it became a necessity on every install.The only issue with it is it does not work on 3/8" copper because the copper does crack every time.No problem though because I just keep one of those 3/8" impact bits that swadges the 3/8" copper in about 15 seconds.No long term trial yet but this unit seems to be doing just fine for now and of course the substantialy lower price than brand name ones makes it better.UPDATE: 4-23-2023So after 9 months with the swaging kit I bumped from a 4 star to a 5 star because it has worked very well and the hydraulic pump aspect is still working very well.I also purchased a bender kit (Black Max) and between the two it is extremely rare that I need a copper fitting - maybe a 90 deg elbow once a year or so.This is not a brand name product, but it seems to be doing just as well as one.One thing to note is having to swage pipes coming out of a wall or ceiling the brazed part of the pipe is generally always facing you so that a visual check of your brazing is a piece of cake.
