Internal tube sealants?

Bigtalljv · 29 October 2013, 05:00

Hi,

So I have patched all visible leaks and the soap isn't bubbling anywhere I can see anymore but my ancient tubes eventually leak out. Seeing that I can't afford to re-tube I'm looking at the internal tube sealants as an option to maybe help my tubes hold air a bit more. Anybody had any experience with them? There are a couple different brand but I assume they are all very similar. Probably a lot like the sealant in my mountain bike tires. My tubes are off so now would be the time to think about flipping 7m tubes around

You've got Hyalon, try the slime?

I've actually though about taking my tubes off my boat (yes, all 128+ bolts) and trying the West Marine stuff:
WEST MARINE Sealant at West Marine
It doesn't say PVC or Hypalon anywhere but someone in the reviews said it worked on PVC.

Besides Slime being water soluble I thnk the biggest issue is that it's kind of thick. The tube sealants say they are much thinner. I think I'd get better coverage flipping my giant tubes. I imagine it's the same type of sealant that I use in my tubeless mountain bike tires, the stuff works great in there.

Your tubeless mb has far higher pressure though and centrifugal forces to spread it within the tube...?

We tried it on one of the ribs. We were told the trick is to spend the day out playing with waves straight after you put it in. It worked perfectly. Don't know what brand it was as our rib repair guy put it in.
