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

Love the mega size bottle, gets the job done no issues at all.

Kept my new hairdo from getting ruined in even the strongest wind. The bright color and unique texture were an unexpected bonus! Tends to get bugs stuck in it though….

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.

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.

Works great. Went through a ton of thorns with no problem!!

Works great. Seems to last longer in Az Summer.

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.

Good quality, will buy again

Bekanntes Produkt, bekannte (Top-) Performance. Schnell und zuverlässig geliefert.

Good product no problems with it.

Utilizzo il Muc-Off No Puncture Hassle Tubeless Sealant da un po’ di tempo sulle mie ruote tubeless (MTB e gravel) e devo dire che è uno dei migliori sigillanti provati finora. Anche se la confezione era già aperta, il prodotto si è dimostrato perfettamente efficiente: consistenza fluida, nessun grumo, e ha sigillato un piccolo foro da 4–5 mm in pochi secondi senza far perdere troppa pressione. Si applica facilmente con il beccuccio fornito, anche tramite la valvola presta. Il colorante UV è una trovata geniale: con una lampada UV ho individuato subito dove aveva lavorato. Nessun odore fastidioso (non contiene ammoniaca). Dopo settimane di utilizzo, il liquido è ancora attivo e non si è seccato. Consiglio pratico: Agitatelo bene prima dell’uso e controllate che la valvola sia libera, così entra in modo uniforme. In sintesi: Sigilla rapidamente, non sporca troppo e dura nel tempo. Anche acquistato “usato”, si è rivelato super funzionante e affidabile. Ottimo per chi cerca un prodotto di qualità professionale per bici da corsa
