Aupoko R134A Valve Core Quick Remover Installer, High Low Pressure Valve Core Remover Tools Kit for R13A Refrigerant Air Conditioner System

The tip that unscrew the valve was too wide and didn’t hold the valve in the tool when pulling it out. I had to screwed it back with the tool and adjust the tool tip a little with a plier, using the new valves to make sure it will stay attached to the tip of the valve removal tool and don’t fall off. That adjustment worked and I was able to make the repair.

They must have taken feedback and improved the design, as this worked perfectly to remove my low side AC service valve (didnt try or need the high side).It's true that the shaft of the driver isnt perfectly centered inside the coupler, but it was easy enough to eyeball it and wiggle the driver onto the valve core. It also had a snug fit, which let me remove the valve without falling off, so no need to crimp down the prongs like others have noted.It took a total of 10 minutes to do this, taking my time and figuring out how to get the prongs to mate with the valve core but it was an easy job and can save you lots of money.Sadly, my valve core had leaked for some time before i caught it, so air got into the system, so it requires an evacuation anyway, but this is still a great tool to have in your collection.Also, it did come with a few valves and a separate valve driver to loosen or tighten the valves one you get it seated.

These are well made and fit the high & low side R134 ports. However the tool does not fit the larger schrader cores found in Dodge and Fords.I thought I got a mis-assembled tool and sent it back. The replacement also lacked a large extractor for the high side. Luckily my leak was low side, so it's repaired and maybe I'll never have to replace the high side.

The tool will not hold the schrader valve after unscrewing, it will just drop back down. Tried a dab of grease as others suggested but i still couldn't get it to stick.Additionally, while dry-testing, there is not enough clearance for the ball-valve to close - you have to back off the threading multiple turns.The two prongs broke after trying to get the valve out.Ultimately - this is a single use tool and it cannot perform its one function. Don't purchase it.

it worked very well, it did the job

I recently used this on my car. I was able to remove both high and low side valves with these core removers and it did not leak. It appears to be a well made unit. However, there are two things that made this a pain to use.1. It didn't grab the cores firmly for either removable or insertion. There's a little fork on the end of these. In my experience with house AC unit core removers, that fork generally grqbs and engages the core tightly enough that you can hold it vertical and not have the valve core fall out of the forks. That was not the case with this. Having read the reviews and saw others having this issue, I used Vaseline and gummed the end of the removal rod and it did work ok. It just should not be necessary to do that. On the upside, the removal tool was able to engage the cores and turn them out without issue.2. When pulling a core out after unscrewing it from the fitting, you slide the removal tool (and the attached core) out past the cut off valve then close the valve behind the core and then unscrew and remove the core removal tool piece from the body of the valve and then put a new valve on the removal tool fork and screw it back down and then open the valve and insert it into the fitting. That's what should happen. This issue I ran into is there was not enough clearance for the cut off valve to close with a core attached to the tool. It's close but it doesn't quite clear. The only option was to slowly unscrew the removal tool back up its threads to get the valve to shut. We are talking a 1/16 of an inch so, you not having to run the cap all the way to the end of the threads, but it is daunting, particularly on the high side where there's enough pressure to launch that tool like a bullet. Nothing bad happened, no freon was lost, but it's poor design and should not be necessary. Had the valve body been a bit longer this would not be an issue. Could this just be a fluke of the cores themselves? Maybe, but I used the cores provided to replace the originals and ran into the same issue. It's possible since they hang so loose in the core remover fork they are just sagging down and not letting the valve close. Still a design issue as the remover fork should fit a bit tighter. So the bottom line is, the units work, they don't leak and are well made, but they could have thought about the design a bit more to make them safer and easier to use.

The thing just saved me $40bux in freon in it's first use.. and was able to use one of the valves supplied in the kit to replace mine, it could be a little better like if it was magnetic I kinda had to fish the valve out of the ball valve part but the pressure in the system pushed the old valve out and nothing leaked so the gas lost was minimal.. it was very easy to use as I seen a video for the $200 named brand version of the same tool, this cheaper(probably Chinese copy), worked totally fine for me.. Hope I don't need it again but if I do, it's already paid for itself ¯\_(ツ)_/¯

Did what I needed it to do. Had a Schrader valve leaking on my 96 suburban, it held pressure (to a point), which I was able to slow by tightening the cap well, but still wasnt a full chargeThis made it easy to remove and replace the schrader without popping open the system, it took me 4 tries to get the valve out1. As soon as you loosen the valve the pressure will push the plunger back, if you aren't prepared for this it feels like the stem came with it; it did not2. got the stem tool pushed back in and felt the valve stem spin, pulled the plunger out and removed it but did not get the valve stem3. tried again with no luck4. slightly bent in the tines on the tool and tested with a spare schrader, had a much better grip, pushed the tool back in and gave it a push and turn and was able to get the shrader valve in. Reassembly was quick and easy, I added a few oz of freeon to my system and it seems much happier now

Worked great for changing the valve steams didn't leak any freon easy to use well worth the money.

My first attempt on the low pressure side was as others have commented on, a disappointing experience with the Schrader valve out but not in the tool when extracted. After giving up on that occasion I played with the tool gap and could see you can make it more snug. Today I had another go and despite my best efforts the low pressure side once again began to defeat me. This time I decided to open and shut the tap quickly (with the tool removed) and as another reviewer commented the Schrader valve shot out into the air and as it did so I recall thinking I hope I can find it as I have no idea which size to replace it with. Anyway it bounced off the garage door and onto the drive. The new one was an easy fit. The high pressure side was text book, the tool fitted perfectly and extracted the valve on the first attempt. The system is now regassed and holding pressure I am happy to recommend this aircon valve replacement kit but patience and inginuity will be required. Good luck.

The low side tool would not grip the scheader valve and pull it out. I read Jon S's review who had the same problem and I slightly bent the tines to tighen the gap as he did and it now grips well. I will dock a star for the improperly set tines and time waisted figuring out the fix. I was getting close to deciding to return it.

Item missing from package.unable to use it.

Le système n’est pas étanche et le gas s’échappe. La tige peut même être propulsé avec vitesse si elle n’est pas garde fermement. Impossible d’enlever les valves avec les tiges. Les valves restent accrochés.J’ai essayé sur une Honda Accord 2005 et Insight 2010.
