GOTH Perhk Bicycle Tubeless Tire Sealant Injector Syringe Kit, Included Sealant Injector and Presta Valve Core Removal Tool?60ml?

The fitting that goes into the valve once you've taken out the core is a little small so it requires quite a lot of pressure on the syringe plunger, otherwise it works very well. It's fairly easy to clean, just suck up some water with the syringe a few times until it runs clear and you can put it away for the next time.The valve core tool is great and it comes with a couple of spare valve cores too.

No fuss and no mess. Simple

Great value for money. Solid syringe and pipes that screw in easily. Just don't tighten them too much or else they may crack. The aluminium valve core remover also works well and is easy to use.

Its a syringe, with a tap and some tubes, core remover and a couple of presta cores. The core remover worked well, was easy to remove it, easy to suck up the sealant (Stan's no tubes - normal, *not* race) into the syringe, turn the tap to off to stop leakage, insert the small tube into valve, set tap to open and inject sealant into tyre, all with no mess or sealant all over the place. Easy to clean. It did the job.Its a useful tool which should last a good while, most important for me is no mess. Enabled me to remove wheel, tyre, clean tyre of old stuff, remove core, re-seat, new sealant, replace core, inflate, wheel back on for the front tyre of my road bike and clean up _everything_ in under 10 minutes.Might not be the cheapest way/solution, but its quick and clean.

First Issue was the valve, upon screwing it into the syringe the Thin Brittle Plastic on the Syringe snapped, OK I can silicone that to seal it.Second issue was the 2 x straws look nothing like the product images & do not fit the valve, therefore the whole kit is useless & maybe only the valve core removal tool worth keeping.The rest is in the Recycling Bin & Amazon have refunded the price paid.

I read some reviews that suggest this isn't fit for purpose but it worked fine for me. I used Muc-off tubeless road tyre sealant and some of the chunkier bits of rubber did clog the thin tube but they were easily fished out with a small screwdriver. I gave it all a good rinse out after use and the syringe, valves and tubes cleaned up perfectly so absolutely fine for repeat use. I'd definitely recommend this system if you're switching to tubeless tyres with removable valve cores and want to avoid the mess of pouring tyre sealant directly into the tyre then trying to get it onto the rim! I had no mess at all with the syringe.

Bought this to help with swapping MTB tyres over.Removing the old sealant through the valve was easy enough with the small tube, as long as it wasn’t forced all the way down.Re injecting the “new” sealant into the new tyre was just as easy.Only downside I can find is the threaded joints can come undone a little too easily.Wish I’d bought sooner!

The only real issue - but it's a big one - is that the syringe spout and the tube attachments supplied are really quite narrow. This means that the tubeless tyre sealant often does it's job and blocks it - doh! Not super useful.
