This is made great. No leaks. The gauges worked fantastic. After watching some YouTube videos I was able to fix my air conditioner myself. Someone recommended shut offs here. I don’t. I bought some and didn’t use them. Not necessary. I just used this kit and a tap for the Freon found here. gohantee R134A Can Tap,... https://www.amazon.com/dp/B085VYKR87?ref=ppx_pop_mob_ap_share My ac uses R22 and this worked great. It’s up and cooling again. It’s going to get even better though. I put a 4 oz can of stop leak Freon and a 15 oz can of Freon in it. The blue gauge needs to get to 75-80 so it can be much better than this. For this price you can have an American made tool and check your ac even if it’s working. If it’s low and you fill it yourself your bills will go way down. I love this thing. So great to know I can fix acs for the price of Freon now that I have this. Can’t wait for my new can to show up so I can use this to make my ac work way better than it is now. It went from not being able to cool. To working well. But having this I know it’s very low and can be much better. This can save you a ton. It’s something you need but might not even know it. If paying people a ton of money to do something simple isn’t your thing pick this up. Check out You Tube too. Depending on your situation you may need a vacuum. I may have benefited from one. But this and Freon seems to be working well enough I don’t think it’s necessary.

Used this to install a mini split heat pump. The hoses feel of rather high quality, and the connections/valves inspired confidence. The threading was smooth and the fit quite nice. The valves closed tightly and didn't leak, and pressure gauges worked as expected without jumping around or jittering. Does not come with the adapter for mini split systems, but this is not a problem with the product.

Firstly, I didn't have any problems with leaking like other folks had...maybe I got luck but I had no issues. I hand tightened everything down and it was perfect. The quality feels solid too, just like the professional manifold set for cars I got from my work. The gauge is nice and steady, no bouncing or flicking. It fit our R410 perfectly as well, I didn't have any trouble threading it on. Double check your units, but our low pressure line (blue hose) went to the higher of the two fittings! Also as far as storage goes, I just keep the yellow end attached to the tank with all valves closed, including the one from the tank, and tuck the rest into a box. Given the troubles others are having, maybe I just got extremely lucky, but I'm one of those folks that, if I didn't have bad luck, I'd have no luck... Anyway, I recommend this set. Got our a AC up and running in literal minutes. We over heat so easily and have pets, so this probably saved our pets lives, and us a lot of misery.
