    Followed BASIC instructions and both leaked air. Did not form a tight seal.

    I like these better than the Stan’s brands because they have a rubber gasket under the washer that threads onto the stem. It helps to keep it tight.

    Was getting a leak around the valve stem on a mountain bike. After put this in it fixed the issue. Great product. Need to sell it with larger quantity.

    They installation was simple. The rubber ring was a nice addition to keep the seal air tight. Good to know you can get good quality tubeless components without spending a small fortune.

    Just got these and threw them on with my new plus size maxxis minions on i35 rims and they fit great, feel super durable, and seal perfectly. 10/10

    Used to replace a damaged valve stem on a wheel with a 2 year old tape job. Wheels held air on the first try, no problem. I didnt use the extra o-ring, but I did dip the rubber end in some sealant before installing, which always helps.
