Thinvik 3.5 oz/100ML Tubeless Sealant Injector for Stans No Tubes sealant.BikeTubeless Sealant Syringe for Presta Schrader Valve Core Removal Tool and Other sealants

Worked great after I figured out how to use it. Hint: use both the tubes for the injector so you can hold up the end of the joined tubes to prevent sealant from leaking!

Wishing I'd bought this years ago! We used with both schraeder and presta valves and it worked extremely well. As I stated in the headline: it was easy to use, quick and efficient. No more messing with removing the tire from the rim and pouring in. I thought about buying the more expensive brand names but so glad I went the frugal route and bought this one. Just buy it!

Easy to use with Stans fluid, numbers easy to read, nozzle fits into presta valve. The valve removal tool works perfectly.This is now in my tool kit for tubeless tire work.

I've used this syringe with Stan's sealant in the past. Thought I would try a different sealant, that is suppose to seal tire sidewalls well. This sealant had much larger particles than Stans. Well, this syringe worked well with Stans, but was extremely hared to use with a sealant that had large particles; the particles clog the thin syringe tube. The particles also clog the syringe itself! Messy and not sure I am able to get those larger particles into the tire at all. Looking for a syringe now that has a larger diameter tube and syringe connector.

Super easy to use, solid seal and several options to fit a value. Great quality and it comes with a core tool! How nice is that! I had one but now I have a spare to keep on my bike.Pro-tip: clean it and the nozzle immediately after use. I use Stans sealant, and the latex will dry and you’ll be throwing this away if you don’t clean it before it’s too late! Warm water immediately after use (suck up some water and squeeze it back out several times) works great.

Works perfect. Makes installing sealant a breeze. Super smooth. Clean it after use and save it till next time.

Con: Syringe tip broke off after about 5 uses, and started leaking profusely. I glued it, but TBD how long that holds up -- the permanently mounted tube is not nearly as transportable as it used to be in the "unscrewed" state.Pro: When it worked, it worked well with Stan's, and was no-mess, easy-to-clean, a 5 minute job to add sealant.

There's definitely a touch for this. If you try to inject too much of the sealant at once into a Presta valve and don't stop every ounce or so to let air out of the, the sealant will spurt out of the valve. Great product.
