This is a self-sealing 12 oz can of R-134a refrigerant with a built-in leak sealer and lubricant, meant to top up an automotive AC system that has lost charge. The self-sealing top lets you use a standard recharge hose and disconnect without losing gas, and the added sealer and oil address small leaks and compressor lubrication in one step. It suits DIYers with an older R-134a vehicle whose AC blows warm and who want a quick top-up rather than a full evacuation and recharge. Against plain refrigerant cans it adds sealer and lubricant; against professional service it cannot pull a vacuum, measure the exact charge or fix a real leak.

Lowest price we've seen: $25.54 on Nov 2 at Kleen-Rite Corp; highest $35.16 on Nov 1. Tracked across 2 stores since Nov 1.
Owners generally report it does what a top-up can do: AC that blew warm comes back cold for a while, and the self-sealing can is easy to use. Many note the result is temporary and that a real leak or a low system needs professional service.
