I've used all sorts of different sealants including Muc-Off and Milkit, but my go to is Orange Seal regular.kitchencity wrote: ↑Thu Jun 01, 2023 9:44 amInteresting - I've had very limited sucess with Dynaplugs even on relatively small ~3mm cuts. If do they hold pressure they almost always fail after a few hundred miles and I end-up having to pull the tyre and patch on the interior. Adding a second... third similarly fails.bobones wrote: ↑Tue May 30, 2023 1:48 pmThis. I would've given up on tubeless long ago if it wasn't for these guys. So good they can make a hole airtight even if your sealant has dried up. Needing to fit a tube is a very remote prospect if you've got a few of these in your kit.
I currently carry a mega-pill, which is not the most weightweenie friendly, but I like the preloaded tubes and the little blade for cutting the tails to stop them catching the frame or brake caliper.
I've used two packs' worth (10) now and not a single one is still in situ... i.e. I've ended up patching the tyre in all cases. There's really no scope for 'doing it wrong' on the install so I think the sealants I've used (Muck-Off and Milkit) must inhibit the bond - what do you use?
When you say "failed", do you mean the little brass tip falls into the tyre and the plug gets ejected, or do you just not get an airtight seal around the plug?
If the former, then you need to adjust your technique to avoid losing the brass tip. If the latter, then, if there is no immediate stemming of the air leak with one Dynaplug, you need to squeeze in a second (or more) along side the first right away. You don't need the assistance of the sealant for Dynaplugs to work, but they need to be a tight fit.
I'm currently riding tyres with Dynaplugs still in them, thousands of miles and many months after their initial insertion.
I really don't rate Muc-Off or Milkit and find that they continue to ooze or bubble and are not effective for permanent sealing.
