[Closed] Is Stans Fluid Magic?

ive never had the fluid seal a puncture in 5 years of using tubeless. I use it when I first fit the tyres to seal the inside of the sidewalls but I dont bother after that.

OP I guess the gaps are too big in the valve.

I've watched sealant (art-latex mix) seal flats during several rides.

There shouldn't be any sealant near the valve. It can clog them up over time actually.

nosedive do you use like a teaspoon of fluid or something ?

I use a mixture of latex (and other things) with some joes no flats stuff i got cheap. I got home from a ride once and accidently knocked a thorn out of my tyre...It wouldnt seal at all! Took the tyre off and found the the latex had all gotten out. Must have been quite a lot of punctures for that to happen 😐

I got a stans syringe that screws on the valve (after you remove the inner) and injected the fluid through that!

I think the amount of air that goes through teh valve probably pushes the sealant away?

I use the syringe as well. You put it in and it then drains away to the tread area of the type. That's why you Ned all the shaking if the bead won't seal. There's no sealant there naturally.

the valve's on the inside radius of the wheel and the thorns are on the outside and the gloop normally stays on the outside

Are you serious? What happens if you get a puncture on a ride then?

If it's a small puncture that seals instantly how would you know?

How come riding the bike will seal the bead properly then?

I don't know but Caffelatex is. Goes from that gloopy swishing around noise to foamed up silence in one spin. Hasn't not done its job thus far...

I have had a few mid ride.....oh got a puncture tyre goes a bit soft. Stop pump it up a bit to get home. Park bike in garage with mental note to fix puncture. Forget for about 4 days, then go to get bike, find tyre still hard and just carry on again. Have also changed tyres and found thorns in them that were not letting air out.
Have happily run all my tyres tubless, tubeless ready (bontrager) and plain old cheapo wire beed WTB non tubless. Good slug of sealer and crack on!

What patentlywill said

Installation involves sloshing the wheel side to side to get solution on the beads, and when you ride the solution will be flung to the outer surfaces. When you're faffing with the valve the wheel will be stationary, solution runs to bottom of tyre etc. When you deflate the tyre there's no solution being pushed through the valve. Innit?

Also, if you pierce a tyre with a thorn or even nail, you do not remove any material from the tyre. When you remove the thorn/nail the incision will close up, the cut edges will be in contact with each other, and be more easily filled by the latex/particles in the sealant.

The valve hole is acually a 'hole', and is significantly bigger than the latex particles, and so will not seal.

yesiamtom - I usually use 1 scoop of fluid, I thought that was normal? good point made though, perhaps I am getting small punctures and I'm not noticing them sealing.

poppa - I usually just check for pointy things and then put a tube in.

nearly all my punctures were pinch punctures which I dont get with tubeless so running the tyres dry after initial sealing hasn't seemed to cause me any problems. (cue massive stranding episode in the dark peak for being smug)
