BelleoneR134a Refrigerant Recharge Kit, AC Recharge Hose Kit with Gauge, R134a Freon Can Tap Recharging Hose with Detachable R134a Quick Coupler, R134a Self-Sealing Adapter for AC Refrigerant System

I have used this on several different vehicles now. Simple to use, easy to read gauge. Hoses are a bit longer than most other similar tools.

GOOD.

I can't really tell if the T-valve opens or closes, so I just do this...screw on can really fast and then adjust the t where it stops leakingThen attach to the low pressure port and adjust the T some more. When you see the gauge "bump up" you know it's opening or open.Holding the charge can upside down helps.This refreshed my 2003 trailblazer AC and now I have ac for the summer. I am thankful that I didn't have to buy an almost $50 can from walmart, and could instead use some generic R134a self-sealing cans I got from Harbor Freight for a MUCH BETTER VALUE.Even for a one-time-job, this will save you money over other conventional AC hoses/charge "kits" (like AC Pro)You'll also maybe need more than one can if it's not a tallboy. I had to use two stubbies to fully fill my system up to the green-band range on the gauge.So glad this works!

This recharge kit was just what I was looking for. I have used it several times and it has worked great. Also a good value.

Works like it should, much better than the cheap ones you get at the parts store that don't have a gauge. Brass fittings instead of the plastic ones that break. I do hvac work and have a couple of sets of gauges but didn't want to put a different refrigerant through them so this was a cost effective way to charge a car.

Easy to assemble, easy to use, and great quality! I got my car AC charged in no time and had no issues attaching to standard R-134a freon! Highly recommend for price, quality and of course the overnight shipping!

Update 8/30/24 - After trying to put freon into my 99 Sienna and thinking it failed I took it to an auto shop. They said the freon wasn't low and there were no bubbles in the site glass. So the recharge kit must have worked and added a portion of the can. The connecting hose, as I said, is very short and it's difficult to make the connection on the low side because the schrader valve is so far back. With the gauge only 8" away you can't read it and it gets in the way when you're trying to connect. The gauge didn't appear to move during the process but the can was cold, so I figured the freon was leaking from the can instead of going into the A/C line.If your connection to the low side is near the front of the vehicle this device might work for you. Before ordering, find the low side connection and if it's more than a foot from the front I would look for a different recharge kit. If you do get this one, make sure the connection needle to the freon can is fully retracted before screwing it onto the can. I can't comment on the gauge since it was nearly under the front cowling. What I could see was the needle going up when the compressor was off and down when the compressor engaged. Other than that it didn't move. Better instructions would have also helped so you know what you're looking at.-------------------------------------------I have a 1999 Toyota Sienna and the A/C was working but on really hot days it took a while to cool down, longer than usual. It was serviced the previous summer. The site glass showed freon (I know it's R134a but let's call it freon) but when the compressor cycled off I got a burst of bubbles and then nothing visible. Compressor cycles on and a burst of bubbles and the site glass fills.The low side connector is way back on the line, right side of the van. The hoses are 8" each so I had about 18" total to work with, including the gauge and brass. I can't see what I'm doing because the gauge is in the way (see pics). At first I thought they had the wrong connector but then I found the quick disconnect adapter and made the connection. I had already connected the can of freon but not pierced it. With the device connected, can pierced, I start the car with front and rear fan on full, recirculate, full cold setting.It's next to impossible to see the gauge because of the short hoses. On the outer edge I can see the needle pointing to about 32. The can gets cold but pressure doesn't change unless the compressor cycles off and then it jumps up to 45, compressor cycles on and pressure drops to 32 again. Can was cold and but none of the fittings were getting cold.I checked the quick disconnect and it seemed to be firmly on the low side fitting okay. I wasn't able to pull it off unless I compressed the brass coupler ring. I swiveled it but nothing made any difference.When I started there was freon in the site glass, none when I stopped. It seems I lost gas instead of gaining any. Gauge never changed from 32 unless the compressor cycled off.On 2 previous vehicles, with a different device, I was able to charge up the freon with no problems, so I have the skill to perform this task. Since the can was cold the freon was going out, just not to the low side. I don't know where it went. Since I can't see anything in the site glass when the motor is running it appears that I lost freon in the system instead of gaining any.I do not recommendI am returning the device.

Easy to use. Good quality
