TWTADE Car A/C Repair Kit - 270PCS Rubber O-Ring Kit 18 Sizes + 40PCS Car Air Conditioner Valve Core Kit, A/C R12 R134a Refrigeration Tire Valve Stem Cores with Remover Tool

I love these!

Only needed one valve but it was cheaper to just buy this whole set.

Product work what I needed it for.

This is review of AC repair kit. It come with a lot of o-rings for your needs. I don't have any AC that is leaking at this time but I have the same o-rings in the past with the same brand and part number that works for me. They quality still looks same when compared. The only question I have is why they describe this as rubber o-ring instead of the HNBR which is the material needed for AC system as they are compatible to use with AC oils. It has a lot of sizes and make sure you compare them or refer to manufacturer to know the right size. The valve core kit also looks like it is of good quality. Size looks similar and of good quality. The tool is also sturdy and should work as described. Orings and rubber are thick. I will update this when I use them.

This has the most common valves and also the O'ring kit is quite extensive. Anyone doing auto A/C work needs a kit like this. If working on an A/C system always replace the valves, evacuate, vacuum, recharge after other work is complete.

One of the main areas for AC leaks are at the valves. Great kit that has an assortment of valves to accommodate your needs. And while your at it, replace those o-rings! This kit has all the standard sizes. Worked great and still holding.

For professional technicians.

Overall good quality o-rings and valve cores. I am finding some of the Subaru sizes dont match up to what is in the kit but it has worked find with most domestics. Overall a good kit to have on hand that should work with most vehicles. Just be aware it may not be a fit for everything.
