AC Charging Hose Tube, 72" HVAC Gauges Hoses Refrigerant Charging Hose for R134A R12 R22 R502 Manifold Hose Set, 3pcs

The hoses take a lot of strain during the summer months. These are extra durable and seal perfectly.

I needed some replacement service manifold gage hoses due to the deterioration of the little round seal in the angled connection fittings. The Burst pressure ratings are the same as my old Brand name hoses. These new hoses look good well made and safe to use. The O.D. size of both the hoses and the connection fittings are a little smaller and is why they cost less than brand name hoses. How long will they last time will tell.

When I connected them to the system the hoses developed bulges all up and down the sides of the two I used ...it looked like they were leaking inside the liner...I have never had this happen with refrigerant hoses...I was afraid I will lose all the refrigerant in the system as well as the oil and refrigerant I had added if I continued to use them and they burst...I was charging a vehicle using R-134a at 95° which is well within the advertised range for the product...I contacted the seller who said he contacted the manufacturer and I was told this was normal since the hoses weren't leaking; also that they bugles would go away once the pressure was relieved...I know from experience that this is not normal for refrigerant hoses and the hoses did stay deformed after all pressure was removed...I am returning the hoses and would recommend caution with this product

High and low pressure lines are correct, yellow line has wrong ends and will not connect to my gauge set. Nice quality set if you get the right ones.

Hoses are standard to do replacement

The ac hose are direct fit.

These hoses are not the best quality in the world but they work and get the job done so I guess that's all that matters.

Bought these to replace my 8 year old Yellow Jacket Type II hoses. These hoses looked like a good deal given the price. Thankfully I actually tested them prior to actually using them on a job. Specifically, they will NOT hold a vacuum. I tested each hose separately using a vacuum pump, digital vacuum gauge and a hose connected directly from the vacuum pump. My pump will pull down to 80 microns give or take, with a digital gauge connected directly to the vacuum port. Connected a ball shut off directly to the pump and attached each hose to that and to the digital gauge. That way, I could test the hose for leak down also. 2 hoses managed to get down to 240 microns. The third would only get down to 2800 microns. All three of them would not hold a vacuum for more than 1-2 seconds before loosing vacuum rapidly. Upon closer inspection I found the seals in each hose were made of plastic. Not rubber as one would expect. I believe that is the main cause of the leakage.Returned and bought real Yellow Jacket hoses. 2-3 times the price but…
