KOM Cycling Tubeless Sealant Injector Syringe and Presta Valve Core Removal Tool by Designed for Stans No Tubes sealant and Other sealants …

The KOM Cycling Tubeless Sealant Injector Syringe is a great piece of kit for bike maintenance. If you you run a tubeless setup on your bike, this sealant injector will make the setup & maintenance easier & cleaner.The syringe holds 2oz (60mL) of sealant & has 2x 4.25in (110mm) sections of tube (3mm outside diameter) & a valve attachment for a total tube length of 10in (250mm) if you connect all. This is important if you are filling from a larger bottle of sealant & the fluid level is low. The tube fits both schrader & presta valves, just remember to remove the valve core.The set I purchased came w/the red anodized aluminum valve core tool. If you want this tool, be sure to choose it in the option when purchasing. The other option is a small plastic valve core tool. This plastic tool work just as well, I have one that I keep on my MTB, just in case. If you lose or misplace things easily, definitely pay the extra for the aluminum tool. The plastic tool is tiny, only a couple cm long. The aluminum tool is more than twice as long & the red anodizing makes it much more visible.This syringe is not a “must have” tool to go tubeless, but it sure makes it easier & less messy. I like that the tube goes through the entire valve stem into the tire, minimizing the amount of sealant inside the stem. This should help save on valve cores getting gummed up w/sealant. I’ve been using the syringe w/Stan’s NoTube sealant & it works flawlessly. After each use, I clean the syringe. I get a cup of warm soapy water, suck it up into the syringe & eject out 2-3 times. I then do it again w/fresh water for a rinse. This gets all the sealant out of the syringe & tube. I’ve been nothing but pleased w/the KOM sealant injector.Thank you for taking the time to read my review, I hope you found it helpful.

Love the no mess ease of use.

Does what its supposed to. Use it on a tubeless mtb. All the shutoff valves are overkill, but no big deal. Clean well after each use

I bought this for my first time setting up tubeless, and the whole thing was super easy to use. It was well worth the money.

Exactly as described, recommend

I read some reviews about how this would not work with Orange sealant, but I just used this with some Orange Endurance sealant and it worked perfectly. Just used the 2 clear hoses so I could stick the hose into the Presta valve stem and dump the sealant right into the tire with no mess at all. Super easy and the Orange Endurance sealant sucked up into the plunger and pushed out with ease.Great product, and refilling my 29" wheels with 4 oz each of Orange Endurance sealant took about 5 minutes total to do. Afterwards, just suck up some water to flush out the hoses and pop the plunger out and rinse it off and you're good to go for next time.

This sealant injector does the job perfectly! The modular design allows you to easily pull sealant from the bottle and then switch heads and inject it directly into your valve stem. No drips and no mess! Just make sure to rinse it thoroughly after each use to avoid dried goopy sealant in the syringe. Bonus that they include a valve stem puller!

Far far better than trying to put the sealent in the side of the tire and then mounting the tire. Metal presta valve core remover works great.
