wile007Bike Tubeless Tyre Sealant Injector Tire Repair Tool Kit Filling Tool,with Schrader Presta Valve Core Removal Tool,20ml

this item works but needs to have much higher volume, 20ml is way too small

Bought this when I realised that I needed to top up the tyre sealant in my bike's tubeless tyres. It didn't come with instructions and, although simple to use, it took me a while to work out that Presta valves connect to a screw inside the nozzle. In order to fill each tyre with sealant I also had to re-fill the piston as it wasn't big enough to deliver the volume that my 700c x 28mm tyres needed. I got pretty messy refilling it when I'd bought it thinking that it would help stop the mess!

This simple and obvious how it works. No need for plunger if your valve isn't blocked, if it is use plunger.Very robust kit and comes with spare seals.

It works - bit loose but not a problem

Thought I would try putting the sealant through the valve as I have seen others do, initially it went well, although you do tend to get a blockage after a while with the little particles, so you will need something to clear the blockage.I guess that issue won't just happen with this one, but with all of them.
