A sealant liquid is a liquid that is inserted into tubeless tires. It is available when a puncture of the tire reacts in a chemical/physical way on the air outlet point, immediately closing the hole.
We were tired of the constant cycling legends about the miraculous mixes to put into tubeless tires. So, we bought six different brand products among the most common ones on the market. Then, we tried to test them in the most technical way possible. Here are the top 6 best tubeless sealants!

Top 6 Best Tubeless Sealants
Top 1: Muc Off No Punctual Hassel Tubeless Sealant
Muc Off remains a constant force in tubeless, as they have refined their sealing formula. Muc Off appears to be gaining popularity, having burst onto the scene several years ago. They performed well in our sealant test and have branched out into several new formulations for specific applications.
Additional particles come in a small bottle attached to the larger sizes of Muc Off. So, you can customize the sealant level to suit your specific riding conditions. Do you want to have better protection at the cost of a shorter lifespan? No problem, the choice is yours. The smaller Muc Off bottle comes with a handy tube to fill your tires directly. If you choose the larger bottle, you will need to provide your syringe to fill them.
Pros
- Efficient
- Fast sealing of tires and tubeless flats
- Multiple choices of size
- Versatile
Cons
- A little prone to clogging the valve
Top 2: ZEFAL Z Rose Tubeless Sealant
ZEFAL Z is a brand of latex-based tire sealant. ZEFAL Z sealants are still latex-based, but they include additives to improve seal performance and puncture protection. These features help seal leaks effectively as they come in different sizes and shapes. It will form a matrix to seal the hole with the latex, making it a good track pump to pressurize the tire.
This function would make it difficult to inflate a tube if you have a flat or a significant loss of pressure while on the road. ZEFAL is the best-known tire sealant on the market.
It is the best tire filler and can work wonders on bicycle inner tubes. ZEFAL is a fibrous binder that means that it contains many microfibers in solution. Most tire refill bottles have an easy-to-install valve and cover removal tool.
You need to use the cover to remove the valve from inside the valve body of your bike tube. Spray a free amount of putty, then close the valve. We can do it while we install the tube in the bike, even before using it on the outside of the bike. It is a good sealer for holes made of oddly shaped objects like screws or wood chips. Anything that creates a defect is sealed better by ZEFAL than with other products.
ZEFAL’s biggest downside is not a long-term solution. Based on corrective experience, ZEFAL can be extended and maintained for several weeks and months. It creates a physical barrier when plugging a hole, unlike some other bicycle tire sealants. For this reason, ZEFAL is a temporary viable solution. It will keep your tires safe during the ride and give you peace of mind for a better experience.
Pros
- Stable over time
- Innovative formula
- High efficiency
- A temporary viable solution
Cons
- High price
Top 3: Stan’s No Tube Tire Sealant
Stan’s tubeless tire sealant is super viscous and effectively coats the inside of tires. Its neat applicator pack fits directly onto Presta valves, so there is little mess or waste. Stan’s tube was the most effective sealant in the test at quickly sealing even the largest holes and sealing.
Stan’s tubeless putty worked effectively. It’s fine formulation was stable at low temperatures but scratched when warmed up. So, it could lose its effectiveness if you ride in warmer climates.
Although we have not reviewed this sealant, we have used it frequently. It effectively seals the tire to the rim and resists small holes well, even if it is quite liquid. It remains quite liquid and therefore does not need to be refilled too often.
The smoothness means we are not sure how well it will cope with a bigger gash. Luckily, we did not have to deal with that when we used tires with this putty. It is also quite inexpensive that makes it a budget purchase. Using a blend of liquid synthetic polymers gives Stan’s Tubeless NTLR its latex-like behavior as it becomes solid when exposed to rapid evaporation. Thus, it repairs holes in this process.
As the wheels spin, centrifugal force drives the standard liquid sealants against the outer circumference inside the tire. Stan’s tubeless NTLR foams and can be forced to puncture any area of the tire carcass.
Pros
- Easy to apply
- Stable over time
- High efficiency
- Versatile and affordable
Cons
- No negative comments included
Top 4: Joe’s No Flats Super Sealant For Bicycle Tire
Joe’s B8 Preventative contains a foaming agent that bubbles up when you get a dish, although Joe’s B8 has found that it is not effective at sealing the holes. As a tubeless pillar is preventative, Joe’s B8 latex formulation is thin. It covers the inside of the tire well and is not affected much by heat or cold, making it an effective option all year round.
Joe’s B8 is okay on small holes, but not so good once the notch is bigger. It is the cheapest sealant. Joe’s B8 was one of the most effective solutions for sealing big holes in the past, but it went downhill quickly. This B8 version of Joe lasts up to four months between recharges. The included valve injector makes it easy to fill the tire.
Joe’s B8 is arguably the most recognizable name in the tubeless cycling market. Stan’s was among the very first to produce a sealant specifically for cycling. They are both based on the same base sealant solution, with Joe’s B8 offering twice the sealant crystals to help repair larger holes.
The downside of larger crystals is that they have to be poured straight into the tire and cannot be injected through the valve core to recharge as it dries. Both sealants work well with small holes, with the racing sealer being more suited for use on gravel or off-road.
Although it plugged the sidewall holes well, it could not match the original version for the larger holes. It is one of the more expensive sealants by volume, but with its longevity and performance. In short, Joe’s B8 is one of the best tubeless sealants.
Pros
- Quick reaction
- Excellent performance
- Can fix extra-large holes
Cons
- On the expensive side
Top 5: KOM Cycling Tubeless Sealant
The KOM tubeless preventative is expensive because it works wonderfully in any situation. The cost and performance are less surprising when you find out that they have tried various recipes for six years with every brand of tire and every style of riding.
The result is a glorious mix of fast-reacting mobility, so it works great for road trips and even big sidewall cracks on mountain bikes. It lasts a long time in all weather without forming boogers, and it even smells pretty good.
KOM tire sealant still performs well in tests. In its standard form, it works and many other sealants on the market. But what sets it aside is the addition of particles. It is KOM’s name for the puncture sealant particles found in the formula.
With its introduction, KOM has since become one of the market leaders. Be sure to shake the bottle before installing or filling. The particles that help seal the large holes will sink to the bottom of the bottle.
For users who want their sealant to last longer with a little less protection, the KOM version of their sealant has claimed a life of two to three times that of the regular sealer. So, you can look up to it at nine months in moral condition before needing to be replaced.
Low cost does not mean poor performance either. The standard formula is an ammonia-free, non-allergic synthetic latex blend ideal for coating porous tires and quickly fixing small to medium-sized holes.
Pros
- Good value for money
- Non-allergic latex blend
- Perfect texture
- High protection
Cons
- Expensive
Top 6: Hutchinson Protect’Air Max Sealant
Launched with the tubeless tire of the same name, HUTCHINSON sealant is specially designed to work quickly at higher pressures. We have only been using it for a few months, but we went through a lot of thorns and other debris without experiencing significant pressure drop.
Not only does HUTCHINSON have a slight coffee tint, but the fluid and light mixture foams when forced through the holes. They create a distinctive creme while sealing. The base mix struggles to plug larger holes and keep them closed once you knock after punching, so HUTCHINSON creates an additive supplement to plug larger holes more effectively.
Pros
- Long-lasting formula
- Affordable
- Mixture without ammonia
Cons
- Does not play well with CO2
Why Should Buy Best Tubeless Sealants
The elimination of the inner tube eliminates the risk of pinching. In systems with an inner tube, to reduce the possibility of pinching the inflation pressure is increased. We should note that tires must always be inflated to the minimum pressures shown by the manufacturer.
Who Should Buy Best Tubeless Sealants
Tubeless tires with sealant glide much better than those with an inner tube. The inner tube and the tire are two independent bodies. The inner tube undergoes a local sliding regarding the tire It involves a certain dissipation of energy that is clear in greater rolling resistance.
Best Tubeless Sealants FAQs
What are the drawbacks of tubeless sealant?
The latex used to fill the tire has a rather liquid state that solidifies usually after a few months of use. It is accentuated if we leave the wheel unused. Once solidified, the latex loses its ability to repair punctures, and also the sliding of the route and safety are lacking.
How much latex in tubeless MTB?
The answer is straightforward. It depends on the section of the rubber and the diameter.
Is sealant safe for health?
One of the other most common features is that most sealants are environmentally friendly. They contain 100% ingredients that are non-toxic, non-corrosive, and flammable.
