Super Tech R-134A Refrigerant Charging Hose with Gauge

This charging hose works great for r-134a coolant. It is made with high quality materials is small and portable and easy to use. I find the gauge very accurate and it's simple to attach and unscrew from different types of units. Overall very pleased with this and recommend this to anyone looking for a good gauge for refrigerant.

I really like this refrigerant charging hose, its simple design and uncomplicated gague makes it my favorite. The 90 degree push and lock coupler makes connecting and disconnecting assembly a breeze. The gague goes up to 200 psi . Its also very affordable, and durable as wellive been using this brand for a while I've never noticed any leaks.

Bought this to recharge my ac in my Honda Pilot. It worked great and I had no problems. I wasn't sure how to work it but followed the directions on the box and all went well.

The house is thick and well designed. The fittings are nice and tight to avoid any leaks. The pressure gauge is very easy to read and it is a nice size the ends have safety valves to prevent the hose from snapping and causing an accident. I live in a very hot state so this will be of some great use

The Super Tech R134a Auto A/C U-Charge Hose with Gauge and Can Tap is a convenient, user-friendly tool designed to help vehicle owners recharge their air conditioning systems with confidence. Featuring an easy-to-read pressure gauge, it allows users to monitor system levels in real time to help prevent overcharging. The durable hose and secure can tap provide a tight, reliable connection to standard R134a refrigerant cans, while the quick-connect fitting makes attachment to the vehicle's A/C service port fast and simple. Ideal for DIY maintenance, this U-Charge hose offers a practical and affordable solution for restoring cool air and improving overall A/C performance.

The hose feels sturdy and not like it's going to explode in your hand the second you hook it up, which is always comforting. The gauge is easy to read and doesn't make you squint or guess, even if you're not an A/C wizard. Everything threaded on smoothly without leaks, so that was a nice surprise. It made topping off refrigerant way less annoying than expected. I only docked a star because the hose could be a little longer for awkward engine bay setups.

Did the job okay. I had a little bit of trouble attaching the coupler to the low side valve - you have to kind of feel it around to make sure it is centered and seated just right before releasing the coupler to lock it on. It's like filling a bicycle or car tire that has a schrader valve with air. I lost a little bit of refrigerant that was already in my car's ac system fumbling around a bit in order to get it seated. Other than that, everything went just fine. The gauge seems to be accurate but who knows for sure - you trust what it tells you and in my case it seemed to be accurate although I added a whole 12oz can of refrigerant and the reading never changed and was always in the green and steady at around 40-45. They say that your car's a/c system is a closed system and if you need to add refrigerant, then your car's ac system most likely has a leak. I could be wrong but I suspect that over time, the constant transferring of refrigerant from liquid to gas and back again by the compressor somehow weakens the effectiveness or somehow depletes it slowly causing a car (over time) to not blow as cold as it originally did. The hose could be a little longer to make it a little easier but luckily my car's low side port is up high and right up front near the radiator. The only reason I can think of as to why they make the hose so short on these things is so that you don't lose refrigerant as it's traveling from the can, through the hose to the intake valve on the low side port. My car is now blowing nice cold air again! ** Note ** Be careful using this thing. Read up on doing it and watch some videos on youtube to help you do it. There are some things you need to know, so educate yourself and be careful. Protect your eyes and hands for safety.

This came up as a blessing in disguise as I had some of my cars to be repaired. I have used this product couple of times and it's super easy and convenient to use. Highly accurate and reliable tool for anyone who likes to work on his cars . I feel it's reliable and relatively easy to use. Easy to use and can be used anyone who is a DIY person who likes to work on his car, his Ac unit or any vehicle. Highly recommend

Works to add freon from self sealing cans, but the gauge is not accurreate. Readings were way higher than my manifolld set which makes it impossible to know if you are adding correct amount of freon. Also you can't use can tap alone with manifold gauge as the connection to hoses on it are compressed fittings and not srew on allowing to seperate from the hose and gauge. It will get you by in a pinch, but add refigererant knowing that you could be overcharging or undercharging due to inaccuracy of gauge.

Defective and/or poor quality. I return it because it seems to leak at the snap-on fittings that connects to the car. Pressure was fluctuating excessively as the fitting was rotated or moved slightly. I verified this with a hose from a different supplier, $30. I used AI to find a better product.
