Review: great performance and peace of mind! - I've been using Muc-Off Tire Sealant for a few months now and it's exceeded my expectations.

No pressure loss, no stopping, just confidence to keep going. It’s lightweight, eco-friendly, and doesn’t clump like some other brands I’ve tried.

## Questions & Answers

**Q: is this C02 compatible**
A: Most likely.... Alot of bike shops or enthusiast's use compressors to inflate tyres after applying tubeless sealant to seat the tyre etc and I've seen riders carry c02 cartridges out on the trails to re-inflate tyres.

**Q: Does this 1 litre bottle come with a tube to pour into valve?**
A: Yes, came with a clear rubber tube that goes over the valve

**Q: Can this be added to tyres that have another brand of tyre sealant already in the tyre**
A: There's no way of us answering this without knowing what the other sealant is.  Best option is to wipe out the old sealant, properly clean anything off the bead, seal and top up again.  If you're going tubeless then you'll be wanting to check sealant levels and re-seat the tyres every 6 months or so so best to start again with a single mixture.

**Q: How many wheels does 1 litre do?**
A: Depends on wheel and tyre size, but approx 10 for a 27.5 wheel mtb. There is a guide on the back of the bottle

### ⭐⭐⭐⭐ One of the best but has some important downsides
*by T***M on 10 April 2021*

I've churned through loads of different sealants in my road bikes and mountain bikes. This one from Muc-off is one of the better ones. Setup was fine, typical level of hassle seating the tyre on the rim. It's one of the thicker sealants so needed a little more time to spread around the inside of the tyre before seating. For me the most important feature of most sealants is the ability to plug a hole or a cut quickly. Here the muc-off sealant does very well, with some caveats. Firstly, you absolutely must shake and invert the bottle before filling. If you don't, you won't get any of the black sealing lumps in and it becomes pretty useless. I forgot to shake when filling one tyre, and when I ran through some sharp flints the sealant happily ejected through several small holes with no sign of sealing. Replacing the lost sealant with some that was thoroughly mixed sealed them instantly. Secondly this struggles when it's very cool and wet (so British winter/spring/autumn and, tbh, summer). On a dry day the sealant works fine at any temperature. But if your wheels are sat in cold wet puddles the sealant doesn't really solidify and continues to seep steadily through punctures. This is a bit of a disaster when you do the usual trick of putting the puncture at the very bottom of the wheel to allow sealant in; you end up with the wheel on wet ground and the water promptly de-seals the rupture. So I have resorted to drying the wheel around the puncture, then getting sealant in by spinning it fast to distribute sealant around. 30 seconds in dry air usually gets the hole sealed. All of that said... when it's working, this seals bigger holes than Stans or Orange Seal and does so more quickly. It lasts far longer too, mine has still been good after six months or so (thanks cool, damp british climate!). It's made me almost immune to the shards of glass, stone, tacks that litter the roads
