Muc-Off Tubeless Sealant

Muc-Off Tubeless Sealant Kit

Tubeless Sealant is hard to live without these days unless you’re one of the rare few still using tubes.  Lower tire pressures, puncture protection, and lower rolling resistance are so good without tubes, but sealant is a must.   Stan’s has coined the word like Kleenex with tissues and many riders think Stan’s = sealant.   There is a good reason for that, it works.  There are alternatives though and Muc-Off Tubeless Sealant has a unique twist with its day glow pink sealant.

Muc-Off Sealant | $12.99/140ml(4.7oz) Kit| Also available in 140ml, 1 liter and 5 liters sizes

The Muc-Off Tubeless Sealant Kit contains the 140ml pouch, measuring scoop, valve core tool and UV torch to help pinpoint where holes are located.  The 140ml pouch is designed to inject directly into your valve without removing your tire.  Personally, I would rather remove my tire to see how much sealant is left.  For my initial use, I added approx half of the 4.7oz package to each Maxxis Forecaster 2.35’s on 30mm internal We Are One Composites Agent wheels.  The handy measurements printed on the packaging made knowing how much sealant I was using a breeze.  Test rides mostly took place in fall 50-degree temps in NC but did include a week in the 80’s of Florida.

What impressed me was that after a couple of months of riding the sealant didn’t appear to have dried up near as much as other brands.  Granted I haven’t been riding in the desert with lots of pointy things, I am impressed by the longevity of the sealant.  Muc-Off sealant is a little thicker than most others, which may help?  Stan’s and Trucker Co sealants seem to dry up quickly leaving the rubbery coating and globs.  I’ll have to test this hypothesis a little longer to confirm.

Muc-Off Tubeless Sealant
After 2 months there are no globs and the sealant doesn’t look like its dried up nearly as quickly as the competition.


  • Appears to be lasting longer than other sealants
  • Biodegradable and non-ammonia based
  • No sign of big globs forming
  • Its pink!


  • More expensive than others

My Take

The sealant does cost a little more than others with 1 liter (33.9 oz) costing $39.99, but from what I’ve noticed it appears to be not drying up as quickly as others and is not balling up.  Like other sealants buying in larger volume is better especially if you live somewhere where it’s dry with lots of pointy things where sealant dries up much quicker.  Overall I liked how the Muc-Off Tubeless Sealant performed mainly due to how long it appears to be lasting.[/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]

    This may be great for MTB pressure levels. Did not seal punctures on my road wheels with 100 psi pressure until the pressure dropped to about 40 psi. This is with small holes and not the 6mm holes at 120 psi the Muc-Off product info claims to seal. No better than all the other products that may be great fro MTB but are road bike fails.

    I have both of my bikes with muc-off sealant right now, a 27.5 x 2.25 and a 29 x 2.6 and i have punctured a maxxis ardent and a forekaster on both bikes and the tiny hole on both tyres never completely seal. Always pouring little by little. I think I’ll be going back with Serfas sealant

    And I already refreshed and put some more sealant and the problem didn’t solved

      Interesting, can you see or hear where your tire is leaking? I didn’t have those issues with Muc-off but am experimenting with another brand right now that I had similar issues with until I added more sealant than I thought I needed.
