Bike Tubeless Tire Sealant Syringe and Presta Schrader Valve Core Removal Tool for Stans No Tubes sealant and Other Sealants Brand

Easy to use, value and easy to clean

Works great, no leaks or drips, but note that the tubing clamp is not tight shut off and sealant gets buy it into or out of the tire because the tubing is too stiff for the tubing pinch clamp. I like the product overall. Easy to disassemble and clean afterwards.

The thicker tubing of this injector allows the sealant to pass easily into the tube. My only complaint is that you have to unscrew the cap to get the plunger out to fill it.

This syringe is perfect for filling tubeless tires, it even comes with an additional rubber seal to go inside the syringe. It works well, but the white plastic tube clamp requires a great deal of force to use which is the only negative I have.

More complex than what should be required for this task. Seems durable, especially considering the price. Clamp does a good job preventing leaking just be sure you squeeze it tightly to engage. It can be difficult to thread on to a presta valve, (you either need to rotate the syringe or loosen bolt which secures the fitting). If you can find a syringe with a tapered nozzle that doesn't leak, for an equivalent or lower cost, that would be a good alternative.

This is my third tire sealant injector and it's by far the best designed one I've ever seen. The combination of the hose clamp on the tube and the removable end of the syringe makes filling attaching and dispensing sealant extremely efficient and easy. Another plus to this injector is that it is extremely easy to clean after use. This is going in my tool box and I highly recommend to other cyclists who use tubeless tires sealant

As another reviewer said, this does not thread on to a presta valve stem. This makes the item completely worthless. On top of this, the syringe is only 20mL which is a little small for the task at hand (most tires take 2-3 ounces of sealant). I'm returning mine.

I really liked the fact that this has such a tight seal, I was worried about getting the sealant all over my driveway/garage floor. Worked great, and cleaned up great.

I bought this for my mountainbike which has a presta valve stem. The tube cannot screw on, it is substantially too wide, because it only fits a Schrader valve stem. Using it on a presta valve stem is asking for trouble and it will leak profusely. Totally useless.
