Ideal for road, gravel and cyclocross riders who want a tubeless sealant that handles higher tyre pressures, simple top-ups and everyday puncture protection.
The Muc-Off Road & Gravel Tubeless Sealant is the brand’s road-, gravel- and CX-specific formula for riders who want dependable sealing at higher pressures than a typical off-road setup. It uses a water-based synthetic latex formula with sealing particles designed to plug punctures quickly, while also helping seal porous tyres and small bead-to-rim gaps. For fast road bikes and mixed-surface gravel bikes, that makes it a smart choice when you want a cleaner, more pressure-friendly tubeless setup.
In practical use, this sealant is easy to work with. You can add it through a Presta valve or pour it directly into the tyre, and the water-soluble formula makes cleanup less painful than many messier sealants. The 80 ml pouch also suits gravel riders well, because it matches the brand’s recommended fill for many 30c to 45c tyres in one hit. If you’re running narrower road rubber, one pouch can cover a tyre with some left over depending on width.
Where this product makes the most sense is for riders who want road-and-gravel-specific tubeless protection rather than a one-formula-does-everything option. It’s compatible with CO2, works up to 110 psi, and has a claimed in-tyre life of 3 to 6 months. In Australia’s hotter, drier riding conditions, it’s worth checking levels more often, especially through summer or if your local temperatures regularly push above 35°C.
Built for road, gravel and CX
This formula is made specifically for faster, higher-pressure tubeless setups rather than broad MTB use.
Seals larger punctures
Claimed to seal holes up to 7 mm, giving you more chance of riding home instead of stopping for a tube.
High-pressure capable
Designed to work at up to 110 psi, which is important for narrower road tyres and firmer all-road setups.
80 ml pouch suits gravel well
The pouch size lines up neatly with the recommended 70–80 ml fill for many gravel tyres from 30c to 45c.
Presta-valve friendly application
You can add it through a Presta valve stem or straight into the tyre, which keeps setup flexible.
Water-based, water-soluble formula
Easier cleanup helps keep tubeless maintenance less messy when you’re topping up or changing tyres.
CO2 compatible
Handy if your ride kit includes CO2 for fast reinflation after a puncture repair.
Zero ammonia and zero natural latex
A useful option if you want to avoid those ingredients while still getting synthetic-latex sealing performance.

Advanced synthetic latex
We use an advanced synthetic latex formula to give you fast puncture sealing without relying on natural latex, making it a strong option if you want tubeless protection with an allergy-free approach.
Biodegradable mineral flakes
These sealing particles help plug larger holes quickly, so you can keep rolling instead of stopping trailside.
Natural fibre sealant particles
Natural fibre particles work with the sealant to close punctures fast while keeping the formula more environmentally considered.
Advanced polymers
Advanced polymers help the sealant coat the inside tyre wall evenly, so protection is spread right through the tyre and ready when a puncture strikes.
Project Green
This product sits in the Project Green range, giving you a more eco-conscious option with biodegradable ingredients and refillable packaging formats.
Great for
Maybe not for
This sealant is for tubeless tyres only and is not recommended for non-tubeless setups. Recommended fill is 40–50 ml for 23c/25c road tyres, 50–60 ml for 28c road tyres, and 70–80 ml for 30c–45c gravel tyres. It can be installed through a Presta valve or directly into the tyre. In hot, dry conditions above 35°C, check and top up more frequently.
vs Orange Seal Endurance
Orange Seal Endurance is the longevity-focused alternative if your priority is stretching the time between top-ups.
vs Stan’s Race Sealant
Stan’s Race Sealant is the workshop-style option often chosen for stronger sealing emphasis, but it is less convenient for valve-through installation.
vs Peaty’s Holeshot Biofibre Tubeless Sealant
Peaty’s Holeshot Biofibre is a strong like-for-like rival for riders chasing fibre-assisted sealing and ride-on puncture management.
One 80 ml pouch is especially handy for gravel
For many gravel tyres in the 30c to 45c range, the pouch gives you the brand’s full recommended fill in one go. That keeps setup simple when you’re refreshing one tyre or setting up a fresh wheelset.
Road riders should measure, not guess
On 23c to 28c tyres, you usually won’t need the full pouch per tyre. Measuring the fill more accurately helps keep the wheel lighter and avoids wasting sealant.
Prep the inside of a new tyre properly
If you’re setting up a brand-new tubeless tyre, clean out any mould-release residue first. That small prep step can make initial sealing more reliable, especially on tyres that weep a bit through the casing.
Hot weather means shorter check intervals
In Australian summer conditions, sealant can dry faster. If your riding is regularly in temperatures above 35°C, it’s smart to inspect it earlier rather than waiting the full service window.
Bike care, tubeless and workshop products with roots in racing and rider-led development.
Muc-Off is a British cycling brand that began in 1991, originally linked to X-Lite UK and the development of an early twin crown bicycle fork. The company grew from its now-signature pink bike cleaner into a much broader range covering cleaning, lubrication, tubeless setup, workshop tools and puncture protection.
Today, Muc-Off is known well beyond bike wash products, with an in-house R&D focus and an expanding catalogue aimed at road, gravel and mountain biking. Its tubeless range sits alongside maintenance and workshop products, reflecting the brand’s evolution from bike care specialist to a broader performance accessory brand.
