Muc Off No Puncture Hassle Tubeless Sealant, 1 Liter - Advanced Bicycle Tyre Sealant with UV Tracer Dye that Seals Tears and Holes Up to 6mm, Pink

I love the applicator and the fact it has measurements on the side. I made the mistake of buying injector and it clogs constantly while this one if it clogs I just massage the tube and it usually gets removed. If not I remove the bottle and work it back down in the bottle. I see that some people got solid bottles or broken bottles. That's annoying and I did get a broken bottle my first order, I returned it and the new one came in perfect condition. If you already have a bottle save the caps, lids, and application tube to save the return process.

Great sealant other than the color. Total joke. Works amazing. Great value for the money. Like all sealants just don’t make a mess and it’s not messy. Good thickness. It saved me on my rim tape leaking long story but I prefer muc off rim tape now. I suggest 20 more ml than you think you need. It’s worth it.

Good value

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.

I like this stuff because it's easy to clean up and so far in 6 years of using it I haven't had a single flat tire, even though there have been times where I've seen the evidence of it working, as shown in the picture. I started out with another very popular brand, but found that it was harder to clean up, smells worse, and is more expensive. The easier clean up also applies to changing tires. It just doesn't seem to make the same chemical smelling mess some of the other brands do.

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.

This is the fifth time that I've bought this sealant. It is really good but, unfortunately, this last 1L bottle came defective or tampered, it is impossible for me to know. I got the bottle, had my MTB wheels ready for them and, when I opened the transparent protective cap, I noticed the sealant was not viscous at all, it is extremely liquid. Also, it has a really particular smell that is not the usual kinda sweet odor that Muc-Off sealant has, and the most telling thing, the liquid is gray in color, not the fluo pink characteristic color of this sealant. I thought of giving it the benefit of the doubt thinking that maybe it was a new formula or something because the label is different from my previous bottle, went to get my ultraviolet flashlight and, oh surprise, it doesn't glow as the original Muc-Off sealant with its fluorescent dye that I use to identify my sealed punctures. So, I think I got ripped off and I worry that people that have never used this product will use it and suffer not having the puncture protection thay paid for, and not cheaply at all by the way. I'm immediately returning this bottle, my MTB bike will be in standby until I get a new bottle of original Muc-Off sealant since now I have empty tubeless tyres on them... I hope the new order gets me the real thing and that this gets flagged because, once again, I worry other people will fall in this scam. Will obviously update this review once I receive an answer because the product, the original one, is great! PS: in the photos, the left one, is my used and depleted previous bottle, and the right one, is the new fake one...

lo mejor en su tipo

I always buy muc-off tubeless sealant for my mountain bike, also have muc-off valves. It's an easy process if you have a tool to remove the valve. I noticed my tyres were losing pressure a bit quicker than they should as they are worn & have a few battle scars like cuts. I decided to top them up with the sealant which has done the trick & prevents future leaks. I usually re seal every 6 months. The 1 litre bottle is better value for money & lasts a while. The bottle cap was damaged when arrived but Amazon rectified the issue. Bought before & will be buying again. Recommended.

Not sure if the mixture is really that thick. Pls refer to the photo. Its not sealing the tyre.

Utilizzo il Muc-Off No Puncture Hassle Tubeless Sealant sulla mia eMTB, e devo dire che è uno dei migliori sigillanti che abbia mai provato. Offre una protezione eccellente contro le forature, mantenendo le gomme in perfette condizioni anche su terreni accidentati e con ostacoli imprevisti. Facile da applicare e senza sporcare L’applicazione è semplicissima grazie alla pratica confezione con tappo dosatore. Il liquido ha la giusta consistenza per distribuirsi uniformemente all’interno del copertone senza creare grumi o blocchi. Inoltre, la formula UV permette di individuare facilmente eventuali perdite con una luce specifica. Protezione immediata e duratura Ho testato il sigillante su diversi terreni, dai sentieri fangosi ai percorsi rocciosi, e ha sempre sigillato rapidamente piccole forature senza perdere pressione. Anche dopo mesi di utilizzo, il prodotto resta attivo e mantiene la sua efficacia senza necessità di rabbocchi frequenti. Ottimo per uscite impegnative Perfetto per chi, come me, usa la eMTB su percorsi tecnici e accidentati. Mi ha già salvato da diverse forature che avrebbero potuto rovinare l’uscita, permettendomi di continuare a pedalare senza problemi. Inoltre, la compatibilità con alte pressioni lo rende adatto anche a un utilizzo su bici gravel o da strada. Rapporto qualità-prezzo eccellente Il Muc-Off No Puncture Hassle ha un prezzo competitivo considerando la qualità e la durata nel tempo. Non secca rapidamente e mantiene le sue proprietà sigillanti più a lungo rispetto ad altri prodotti provati in passato. Conclusione Se cerchi un sigillante tubeless affidabile e di lunga durata per la tua eMTB, il Muc-Off No Puncture Hassle è la scelta perfetta. Facile da applicare, protegge in modo efficace da forature e ti permette di affrontare qualsiasi uscita senza preoccupazioni. Consigliatissimo!

Bardzo wykona butelka. Mleko działa tak jak inne - zatkało dziurę więc działa.

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.
