3 Pcs AC Manifold Gauge Hose Set with Self Sealing and Puncture Style R134A Can Taps, R134a Adjustable Quick Couplers, Refrigerant Tank Adapters for A/C Refrigerants

Every thing worked as advertised. I did note that several reviewers said the hoses don't fit. I discovered they do fit older gauge manifolds, but don't screw on as far as older R12 hoses use to. They reason why is due to the large & tall seal inside the hose ends. Just screw them on snugly and they work fine.

Seems to be good quality. Fitting all fit tight. They recharged my system with no issue.

The ring gaskets are a little oversized and in some cases hard to thread in place.

these look and feel very cheap, the quick couplers 'might' work, I doubt they will seal. I will be buying something better and more use-able. The hose fittings do not fit a good set of gauges, you will have buy adapters for all 3 hoses to fit a decent gauge set. I would not buy these, get something better. Don't waste your money on this one.

The overall quality the items in this kit is very good, with one major flaw. I purchased this kit to fill the ac system for a 1970 Chevelle that I converted from R12 to R134a. I connected the lines to my vehicle and easily added one can of R134a refrigerant using the tap for resealable cans. I connected a second can using the same tap and no refrigerant came out of the can. After struggling for two days, I discovered the major flaw. The tap/can seal was blocking the flow of refrigerant. To resolve this issue, I replaced the original seal with an "O-ring", see the photo. Save yourself a lot of frustration and replace the seal before attempting to add refrigerant.

Worth the money. Use it couple time already works well.

This hose kit is for R22, and R12 systems. These hoses don't fit the newer R134A system gages. I able to use the high, and low line connectors on my Older gages set.

It is a nice set the valves are just like the original ones that came with my manifold set
