10 PCS Air Conditioning Valve Cap, High and Low Pressure Air Conditioning System Port Sealing Kit, 0.5 "/13 mm 0.6 "/16 mm A/C Service Repair Cover, Universal for Most Cars (Black)

Perfect fit for standard sized caps! They are made from high quality material, with o-ring inside of cap it offers great functionality with no leaks, great value for the money.

Works exactly as designed on my Land Rover LR2 and LR4

There are not that many options in sizes when it comes to AC high and low pressure fittings yet the high pressure cap did not fit

They did the job

The high pressure caps have rubber gaskets, but the low pressure caps do NOT have rubber gaskets, so they will not work to prevent leaks in case you have a known or unknown leak of the schrader valve

It seems I'm always missing one of these and the do help protect the system

Be advised: The low pressure side caps included in this kit don’t fit a 2016 Ford Fiesta - they’re too big. I was in a bind and used electrical tape to hold it until I get the right size.

Absolute garbage product. These replacement caps ended up costing me way more money than what they cost. I checked the fitment before ordering and it was a match for my vehicle, so I ordered them to replace a missing cap. I only needed one and installed it and seemed to fit as it should only to realize I had no cold A/C about 3 days later, since the only thing I had done was replace the cap 3 days earlier I checked to see if it came off only to find that the center nipple (with no rubber gasket by the way which I later found out needs one) had broken off jamming inside the port and letting all the refrigerant to leak out as it was causing a pressure on the port to release it kind of like a tire valve when you press on it. I had to unjam the port and take it into a mechanic to have the refrigerant refilled at a cost of $125 as it was completely empty. This product should not be allowed to be sold and seller banned they are responsible for an unnecessary expense.
