Stan's 2oz Sealant Injection System
A must have for easy tire sealant application and tire sealant recycling. Makes application of tire sealant quick and easy. Minimizes waste and mess of tire sealant. Allows you to measure the amount injected into each tire. Can be used to draw tire sealant out of a tire and re-inject into a new tire. Saving from waste of tire sealant when switching to new tires.
Use this once and never use a cup again.
The idea is great and I'm sure it works great with valve stems that this can thread on to, but seems it is not designed to use with the Mavic dismountable valve which has no threads to attach the injector to the valve. I'm trying the 2 oz refillable bottle next time.
You could make one yourself but it's cheap enough, just get it. Beats pouring fluid right into the tire before mounting it!
I like the idea of not having to pop the bead on the tire as the other reviewer stated. It did not come with instructions though, and the first time I used it to refill, it was a bit of a trial and error learning curve. Best thing is to go Stan's website, or you tube to figure it out. Would be nice if there was a clip to pinch off the tube when filling it up so you could release it after you've screwed it onto the presta valve.
Love not having to pop the bead on my tires. Just remove the valve core, fill the injector, and you're good to go!
