With our tire sealant injector tool, adding sealant is clean and straightforward — moreover, you’ll never run the risk of having too little sealant to keep your tubeless tires safe. While it’s true that sidewall cuts are often way bigger than 6mm, or an irregular shape, very few manufacturers say their sealant will plug tears bigger than this so it’s a valid cut-off point. Tubeless wheels feature a rim shape that is optimized to work with tubeless tyres, but they will work fine with tubes too.

KOM only recommends using low-ish viscosity sealants that don’t use large particles, such as Stan’s, Orange Seal, Finish Line, Caffelatex, and Slime tubeless sealant. Even testing in a stand is fraught with challenges as it's an ideal situation and these sealants will do a good job under an ideal scenario.The spray is strong enough to break the latex droplets allowing isoprene molecules to link to each other forming a solid plug. When setting up road tubeless tires with sealant you might have a bottle with a pointed cap that lets you squirt it into the mounted tire through the valve (you first must remove the valve core).

The kit originally only used the two longer pieces of tubing, but they added a valve (above, bottom-left), which can manually stop the flow of sealant. You never run into the issue where you can't get the core to stop leaking air because it's partially clogged.Speaking of valve stems, KOM Cycling representatives said that their injector is compatible with most valves (one notable exception is E*thirteen). Worried that our Tubeless Tire Sealant Injector won't work with your favorite brand of tubeless tire sealant, like Stan's No Tubes Tire Sealant? The obvious downside is that it only works with small punctures, so it’s perfect for race day situations where the road is smooth and it's unlikely you'll encounter a large puncture. Like Stan’s original sealant, it performs well with smaller holes, but doesn’t plug larger ones as well as top performers.

Muc-Off is one of the leaders in tubeless technology, so it’s no wonder that its sealant is among the best.

You’ll just have to adjust the dosage to account for the different wheel and tyre sizes, according to the manufacturer’s instructions. If you use a syringe to add it through the valve once the tyre has been seated it “will plug any syringe or valve hole you try to pump it through”. With an 80mm or longer valve, the injector straw would not reach all the way down to the bottom of the tire, meaning that you couldn’t remove as much sealant. The thing is that with a good pump and tape that is set up correctly, you shouldn't need extra flow to seat tubeless tyres.When we first squirted the full 140ml there didn’t seem like much left in the bottom of the tyre, but we needn’t have worried because this luminous pink gunk sealed the 2.
