Slime 2080-A Tubeless Tire Valves 1¼", TR 413 45, Schrader valve stem, pack of 2 valves

It does what it says.

Excellent product. Doesn't leak, and was relatively easy to install. Should last a long time

Put these on my Cadillac XT5. Replaced all 4. They work great and keep the air in the tires. They use a battery and can last up to 5 years. These were the name brand that replaces the old ones. Can’t go wrong with them. Easy to use. If you do it at home once they are install by a dealer you will need to program them on the car. I purchased a tool from Amazon. My car started a set up from the controls inside and I went to each tire with the tool and the car would beep it recognized the tire then I would go to the next tire and then third, the fourth and after it was done, it would beep twice. The first part that you read will be the front passenger tire, then the rear passenger tire then the rear driver side, then the front driver side. After that you were done. It lets you know how much air is in each tire at all times.

It was a bit of an effort to push through from the inside to the outside of the rim but seemed strong enough to take the twisting and pushing and little pulling to get it through. Several days later the new tubeless tire matched up with this valve stem and still well pressured up!

Used this on a gas mini bikes rims. Worked great. It’s cheep and works.
