Orange Seal Tubeless Tyre Sealant 8, Orange, One Size

Terrible sealant. A mere 4 days after buying this, my bike was stolen! Just joking... It seems to be great sealant. The slow leak disappeared after the easy injection process. Now I just need to buy a bike to go with my remaining sealant.

I used an entire bottle to fix a slow puncture on my car that had alluded detection and repair. Recommended.

This sealant worked first time with a new set of tubeless rated Continental X King tyres which had several pinholes in the sidewall. This was discovered when I received a fine spray of the sealant in the face when inflating the tyres to about 40psi.

Easy to use, expensive - only used this as my supplying dealer used it when bike set up.

As a product, I have no problems with this sealant. I put the full bottle in my 20x4 fat tire and it quickly sealed the puncture and has held up after a further 5 mile ride. I have two criticisms though. It doesn't come with a valve removal tool, so you're expected to already have one. I didn't so I had to buy one, further delaying my repair. The 2nd criticism is that the tube is too small. I could barely get it over the schrader valve, it took some real jimmying to get it a fraction over and of course it popped right off while trying to use it so I had to quickly pause the filling and resort to syringing the rest in.

Had a persistent (and not that large) hole in my rear tyre that re-opened every time I pumped it up to 80 PSI or more with Stan's sealant. Annoying on a road bike. This stuff fixed it first time.

so far spot on

Used in inner tubes rather than tubeless as constantly have problems with tubeless set-up. Have used on many gravel rides and have not had any punctures as yet so seems to be doing a good job
