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.

It works well. It will pull sealant up and then the small cannule fits inside the valve with the core removed.

Every tubeless tire owner should own a kit like this since refilling sealant is super easy and isn't something you should be paying a local bike shop for. The kit is a great value since you get the syringe and a core removal.

Great value. Arrived faster then local shop could get it in stock. Valve removal tool durable enough to toss in saddle bag and use multiple times. Keeps the mess down and easily cleaned for continued uses.

Love the no mess ease of use.

If you run tubeless, this is a must. So much easier to put the juice in AFTER the tire is locked in place. Also, about every 6months to a year, it is good to re-juice, and with this you don't have to open the tire.

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.

Used with Stans, worked great, no mess, easy to clean, no clogs or drips when syringe was full. Valve core tool worked well, aluminum, good quality.
