HVAC 油圧スイングツールキット 銅管用 3/8インチから1-1/8インチまで拡張

Great product been using for about a year now every day use no issues

Robust feel and easy to swage. Keep in mind that with every pump you want to rotate the tool 90° to prevent your line set from cracking. The feel/operation of the swage tool is smooth but you may have to press down a bit to really get it to expand. As much as I hate the price point, sometimes you just got to bite the bullet to get something good and this was it.

Same quality as Hilmar at a fraction of the price. Absolutely one the best tools purchased this month

I gave 4 out of 5 starts because I had to make an adjustment to achieve perfection. I purchased the 90 degree model that is a bit more expensive. I doubt there is much difference in the two function wise just hand comfort wise mostly. The fact that it comes with the wide range of copper size dies in the box and is 6 times cheaper than the name brand with the same number of dies is a great value. First going to address some things I saw in other reviews. During testing I made at least a dozen swages in both 3/8 and 3/4 SOFT HVAC copper (The kind that comes rolled up). Not one split at all even when the tool over-travelled. I had some new 3/8 and 20 year old 3/8 and 3/4 and not one split. I did not need to anneal the copper but I was prepared to. I do not find it "Cheaply made" as others have said in reviews. It is heavy, sturdy and I think for my lighter, non professional needs will be just fine. I saw one reviewer claimed there was some kind of oil or lubricant all in the package because it leaked out the hydraulic fluid and it did not work. Impossible, this thing is pneumatic which means it uses air. Maybe the grease tube they include leaked but it would not prevent it from working. They include several spare seals in the package in case of seal failure which is nice. The tubing cutter worked very well and I believe has a space wheel in the body (I haven't opened it yet). The reamer also worked very well, I was surprised because the head seems to wobble a bit more than my others but it did a great job cleaning up the copper after a cut. One of the things I like about buying cheaper over-seas knock-off products is they are usually easy to tweak to get the value of the often 5 times the price name brands. That is what I did to stop the over travel where it made the swage too large and the fit was very very loose. See photos. How did I fix the over travel? Without a tubing die installed you will note there is an metric Alan wrench style set screw on the side of the metal collar the die attaches to. That prevents you from unscrewing that part from the rest of the unit. If you loosen that set screw and while there is no pressure in the system you can unscrew that outer cap so it will come off easily and reveal a large heavy duty return spring inside and the remainder of the parts. I considered what causes the over-travel of the tool making the swages too big I knew that meant the tool moves too far outwards. I printed a few spacers with my 3D printer to gauge what was the best size to prevent it moving as far. For MY unit, meaning your mileage may vary, I printed a 19mm ID, 28mm OD and 4.5mm thick 100% solid infill washer/ring/spacer printed from PETG. The 100% solid infill is because as you squeeze down on the handle when it is bottoming out anything not solid crushes in. Even with 100% solid part it still crushes a little and shapes itself to match the heavy spring. With the outer collar removed and the spring off place the part over the cone and press it all the way down against the surface that the spring comes into contact with and reinstall the spring and outer collar and test. Keep in mind different printers do different things so for example if you find it not returning to relaxed state when you open the side valve your OD might be too large so adjust. Making that change the 3/8 is just a little loose meaning if I put two parts together and turned sideways they would slip apart. The 3/4 however was snug enough to stay together. With a 1/2 penny adjustment this unit will perform very well for my needs.

Awesome tool never buy another copper fitting
