Tyre Sealant in Tubes

[TK-Sp3cialiSt]

It depends on the pressure you run, as well as a few other things. I have sealant in my road bike tubes, but only to stop slow punctures and air from leaking out over time... Works well, but always have a spare for actual punctures as i does not seal pinchea and piercings

I have done exactly this in my childrens bicycles, Daughter has 20" bike with tubes, also on my boys balance bike, Have used Ryder sealant.

we went to Magalises for a week a short while ago, first day one wheel lost a bit of air because of all the thorns, just pumped the wheel up again and with the pressure in the tube the sealant was able to block the puncture.

 

About 3 weeks ago I bought myself a new bike, and riding exactly where my kids ride I had a puncture in the first week, Still no punctures on my children's bikes. (I have since then gone tubeless on my other bike.)

 

Have a look at the following youtube clip if the valve has not got the removable core.

Haha, as a noob I ran this way for a while. Fluid tyre sealant from Makro, works like a bomb. 95% of the time, for the other 5% have them carry a tube. Takes all of 5 minutes.

Paulm you can buy tubes with the sealant already inside. Both Spez and Giant sell them. Other makes too. No mess no fuss. Been running these in my 26er for yonks. When you get a puncture some sealant will seep out between tyre and tube but not really a problem if not frequently changing tyres. Takes care of all small punctures but not cuts, snakebites or big holes

cuts, snakebites or big holes

Those were the only types of punctures I got when I was running slimed tubes, with tyre liners....

Ha ha...stands to reason. I guess all the little holes just quietly looked after themselves.

 

Liners and slime tubes? You must be riding some very rough country.

Tubes with sealant works better than tubes with no sealant, my 26" still has sealant but my 29" have been converted to tubeless. Small punctures can easily be fixed without patch and solution by inserting sealant into the tube fitting it to the wheel and pumping it up.

Sealant in the tube won't seal your most common puncture, the snakebite. Going tubeless prevents snakebikes from happening as you have no tube.

Does not want to go tubeless.

Does not want slimed tubes.

 

Yes sealant in tube works.

 

Youtube is also your friend.

The last straw for me was riding Van Gaalens, getting snakebite, trying to patch said snakebite, spending more time mending the bloody tube than riding, eventually giving up, and walking back next to the road.

 

Got picked up by Eric who hapened to pass me on his way back to the farm.

 

It was quite late on a saturday afternoon and the sun was getting low.

Perhaps someone needs to explain the difference between slime and sealant?

 

Wait I know... people think slime is sealant, but it's snot.....

[HOEKVLAG]

I've never seen sealant work in tubes - road or MTB - even though on most of the occasions the rider was convinced that it works perfectly. Therefore I don't trust it at all. Maybe I'm just the bearer of bad fortune...

 

Tubeless systems on the other hand...

Before I started using this I use to get flats all the time. Tubes were like a monthly expense for me. Even buying the slime filled ones didnt help. I got fed up and headed to lbs for tubeless conversion. When I got there the guy recommended i try this first.

Now it may just be co-incidence. But its been at least 6 months since my last flat.

I have never had a flat since using this.

I've changed tyres 3 times and actually re-used the same tubes I filled these with.

 

Bear in mind that I run schrader valves. I just prefer them.

I use a small valve removal to to take out the valve and deflate the already slime filled tube.

A few drops will squirt out when deflating but thats it.

When I say deflate I mean actually deflating it entirely. Not just enough to change the tube.

When I changed tyre widths I bought a new tube to match and filled it with this.

I deflated the old one entirely of air so I could put it in my camelback as a spare. Just incase.

The mess is barely noticeable if any at all.

 

I was on a ride recently where a buddy running tubeless got a flat. I laughed at him the same way

guys running tubeless laughed at me before I started using this. Never looked back.

Incase you're wondering, the tubes I used were giant and continental. The tyres I ran them with included ardents, xkings and blackjacks

Now it may just be co-incidence.

Has to be. I'm with RocknRolla on this one - Slime is NOT a sealant. And, yes, I did try it myself. Before going tubeless (bless the day!), I tried Slime in tubes (Conti) with Mounting King and Race King tyres. I still got flats on just about every ride (sometimes even multiple punctures on a single ride). Added tyre liners out of desperation. That, plus Slime in tubes, just resulted in extremely heavy wheels. STILL got flats. Trying to fix a flat whilst out riding is no fun - everything inside the tyre is slick and green. Add some dust, sweat and tears to the mix to concoct a special blend of hellishness that both you and your bike will get covered in.

 

Perhaps real sealant would work better in tubes than that green snake oil, but if the OP rides his bike just a couple of times a year, how many flats could he be getting?

I used slime in tubes for years, worked perfectly, wouldn't ride tubes any other way. Got some pretty serious holes that the slime sorted out perfectly, some from broken bottle etc. Even got a pinch flat one day that needed a patch, squeezed the slime away from the area of the hole, did the patching exercise and was back on the road. Granted tubes can't handle embedded debris like thorns/nails etc as well as tubeless as the thorn can make multiple holes if it is not removed in time, the key is to properly inspect your tyre if there is any air loss while out riding. Sealant like Stan's is not great for tubes, must be the slime stuff that lasts for the life of the tube, doesn't dry out of need topping up.

 

Just a heads up on the presta tubes with none remove able valves, you can still remove the valve lock nut off the shaft with pliers, then carefully slide the shaft into the tube(holding/pinching it to one side in the tube wall so it doesn't lost) feed in the slime and then carefully thread the shaft back up the valve stem and put the locknut back on. Not easy but doable.
