No Puncture Hassle Tubeless Sealant - Advanced Bicycle Tyre Sealant with UV Tracer Dye That Seals Tears and Holes Up to 6mm

I’ve gone through a lot of tubeless sealants over the years, but Muc-Off No Puncture Hassle is in a class of its own. It’s super easy to install, coats evenly, and seals punctures fast. On my very first ride after using it, I hit a thorny section of trail and the sealant handled it instantly—no pressure loss, no drama, just kept rolling. One thing that really surprised me: it actually smells good. Most sealants have that harsh chemical odor, but this one has a much more pleasant scent, which makes setup way less messy and off-putting. Little detail, but it goes a long way when you’re working in your garage. The UV detection system is genius—I can quickly check coverage and feel confident before heading out. Plus, it lasts a long time without drying into clumps, so I’m not constantly topping it up. And when it’s time to swap tires, it doesn’t leave behind a gummy nightmare. This sealant really lives up to the “No Puncture Hassle” name. Reliable, effective, and even enjoyable to use. I won’t ride tubeless without it.

Work for tubeless setup on MTB very well and smells to good to be true.

I've had at least two punctures that I know of since switching from tubes to Muc-Off Tubeless Sealant. First was a roofing tack that went straight into my tire. I pulled it out, sealant bubbled from the hole for about a second, and then it stopped. Didn't lose any tire pressure, and the seal held. Second was a small gash in the sidewall right near the rim. Now this one didn't seal up on its own, but the sealant did reduce the amount of air escape so I didn't have a sudden catastrophic loss of pressure. It took two bacon strips to plug the hole, and then it sealed and surprisingly held for several weeks before the bacon strips popped loose, and I just replaced the tire. To be fair, that's a tough situation for any sealant to deal with, so I'm impressed with how well Muc-Off performed. Other things I like: the bright pink color stands out and is easy to see if you're hunting for a leak, it remains liquid in the tire for a long time, it smells like a fruit smoothie, and it washes away with plain water.

Can’t go wrong with this. Great seal and no leaks. Bottle will last forever and although sealant is messy coming off it’s not going in.

The real question is, "Does this product seal punctures?" The answer is, "Yes, with reservations." During the last couple of months, It has sealed four punctures for me and my riding buddies. All punctures were caused by "wire whiskers" (apparently from worn out automobile steel-belted tires), and thorns ("goat heads"/"puncture weeds"). BUT, it failed to seal a 1/8" glass cut. Could the cut have been 1/4"? Possibly. In any case, it failed to seal, and after running out of gas cartridges, there is no way to fix the hole (short of inserting a tube), because the sealant requires some pressure to force it into the puncture. Also, the first time you use this product, it isn't as mess-free as advertised. The learning curve is short, though, and subsequent times are much better. Good news is that spilled sealant cleans up easily with a damp/wet cloth. Incidentally, I now put in 60 ml. of sealant every two months, i.e., twice as often as recommended. I do not bother to remove the sealant still in the tire when I add new fluid. This doesn't seem to make a difference, and it saves a lot of work.

Works very good

Think I prefer this to Stans. I have had better outcomes and has been stable in my road bike for a while. Easy to see when you have hit something!

Use it every six months or when I replace MTB tubeless tires. No complaints.

Good product no problems with it.

Un indispensable para mí MTB. Se agradece mucho el efecto que hace a la vista para detectar fugas. La calidad parece muy buena, lo recomiendo

As usual a quality sealant from muc-off. A bit expensive compared to others but it’s worth it because the sealant is quite thick and lasts a long time. Also I have never gotten a flat tire even when the tires got punctured.

This is a messy process but works.
