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

This is the easiest way to add sealant to a tire is to remove the valve core and inject sealant into the tire via syringe.How It Works:1. Using the syringe, affix the long tube to the syringe, and fill with your tire sealant.2. Remove valve core using the provided valve core tool; I personally used my Park valve tool, it’s larger than the one that is provided and is easier to handle because it provides more leverage.3. Insert syringe tube through the valve, and inject tire sealant.4. Replace valve core.5. Add air pressure.6. Swish tire so sealant thoroughly spreads inside the tire.7. Go riding.TUBELESS TIRE TIPS:1. Affix tire to rim. Sometimes tires can be a pain to install. You can lube the tire with soapy water (using dish soap and water mixture) to help the beads set easier.2. Without any tire sealant, inflate tire until you hear beads set; you will hear a piping noise when a beads set. One tire has two beads, so you should hear two pops. The reason you initially inflate the tire without sealant is because if your tire pops off the rim, you will not have a mess of tire sealant everywhere.3. Once the beads are set, deflate tire and fill with tire sealant as I explained above. The easiest way to add sealant is to remove the valve and use the syringe to inject the sealant into the tire.4. After tire sealant is added, add air pressure to the tire.5. Next, you need to get the tire sealant spread around the inside of the tire to ensure the sealant will do its job. Swish tire so sealant thoroughly spreads inside the tire. Basically, you should perform a multitude of movements like wobbling the tire from side to side (all sides), rotating the tire ect... Essentially, you want to get the tire sealant to cover all the areas inside the tire.Last. this cleans up easily.

After getting some 18 punctures in two tires by riding over one puncture vine, I decided to put some old fashion green slime in my fat bike inner tubes. Unfortunately, the inner tubes have the smaller presta valves and not the larger Schraeder valves. Green slime has tubing for schraeder valves, but not for presta. I decided to buy this injector kit and I was able to do the job without difficulty. The kit contains a small plastic wrench to remove either presta or schraeder cores. The wrench includes an extra hole to attach it to a lightweight key ring. I had no trouble using the wrench, but my spokes are widely spaced on the fat bike. The wrench acts a like a handle that may hit spokes for wheels where the spokes are more dense.As shown in the picture, hoses come with the syringe. The hoses were easy to attached to the syringe. Sucking up the slime was fairly slow - maybe 2 -3 minutes to get 1/2 full syringe. The discharge of the syringe went fine. I was careful to wipe the outside of the tube with a paper towel before inserting it into the valve stem (core removed). The tube went well past the valve stem, and no slime gunked up the stem. Everything cleaned up quickly with a few water rinses. Totally reusable. Though it looks like a simple disposable syringe, the plunger seems well made as there was no leak by when pulling vacuum to suck up material into the syringe. Everything was nicely package in a box that also facilitates saving the syringe and hoses for reuse.

Switched to tubeless on my bikes and figured that for the cost of this and maintenance going forward this would be a good investment. I knew nothing about setup so took a little while but this tube went deep inside the valve so hopefully didn't gum everything up after reinstalling the core. Very little mess with the Orange Endurance sealant, easy cleanup with water. Only thing may be that the cut off valve makes it impossible to dip to bottom of the larger size sealant container so getting last few ounces out may be more tricky. In all gets an A, probably A+ if you buy the better valve core tool with it

As part of the legion of road cyclists wanting to venture the path of the tubeless road tire, I have to share my experience with this syringe setup. Looks simple enough, and it is. You have an attachment that has a shutoff valve so you don't spill sealant before injecting into the tire, an extra hose that I assume is for sucking out sealant through the valve with the core removed, and another hose that threads onto the end of the syringe and that firmly attaches to the tubeless valve itself. It also has a plastic tube that is also used for removing the valve core. I attached all the hoses, added my sealant, attached the hose to the valve on the tire. Open the valve and inject your sealant of choice into the tire. I got no mess, and no problems with the sealant I bought for this purpose. This thing just works, that's all I'm gonna say. It has everything you need and nothing you don't for this job, which was done by an absolute beginner in this case. I'm happy, which is all that matters today! Take my money anytime!

Works perfect with no mess from adding tire sealant
