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

Worked like a champ ! Easy to draw the sealant from my bulk source and just as easy to inject. No leakage whatsoever. My previous use of sealants always seemed to end up in a bit of a mess......not this time! BTW used Stan's sealant which has worked well for me.

Worked as advertised. Good value!

This was my first time using tubeless tires. I bought tubeless ready rims, tires, and the special air connectors. I used this kit to add liquid via the air connector. It was precise and there were no leaks or spills even when I changed the needle end piece over to the flexible end piece with liquid already loaded. Cleanup took only a minute. It's my understanding that each rim company has their own filling suggestions. Mine now has them written on with permanent marker. I doubt I'll need to but I'd buy this again.

This is cheap and works very well with Presta valves. However the valve on the syringe is rather weak (others have reported the same issue) and broke at my third set of tires. ( I dropped it :( ). Nonetheless, I got 18 months out of an $8 tool, not bad considering that the top blue brand costs 3 times this.

This is the sort of tool you use 2 or 4 times a year. It works perfectly when it’s new hopefully will work for years.

The Thinvik 3.5 oz/100ML Tubeless Sealant Injector for Stans No Tubes Sealant makes adding tubeless bike tire sealant super easy and accurate. Deflate the tire, remove the Presta valve core with a cheap core tool, measure sealant, squeeze it in the open valve hole with the plunger, close everything back up, and rock-and-roll baby! It is easy to clean up, and will last a long time. It seems like a good value for the price, and I would buy again, though I doubt I ever will need to, unless it gets stolen.

Works good

Well designed

使いやすくコスパもいい

Muy bien y antes de tiempo.

Ottimo prodotto

Funktioniert super. Eventuell die dichtmilch durch ein kleines Teesieb in die Spritze füllen, weil die Milch manchmal Klümpchen enthält, welche die Spritzenspitze verstopft. Habe Continental Revo Seal als Dichtmilch verwendet.

The syringe for the product was not included so i have ended up with a very expensive tiny tube. If i could leave 0 stars i would
