Ideal for road, all-road and gravel riders who want a higher-pressure tubeless sealant that is easy to top up through the valve and practical to keep on hand in the shed.
The Muc-Off Road & Gravel Tubeless Sealant 500ml is built for riders who want a tubeless setup that suits road, gravel, CX and commuting use, not just low-pressure MTB riding. It uses an advanced synthetic latex formula with biodegradable mineral flakes and bamboo fibre particles, and it can be added through a Presta valve stem or poured directly into the tyre. For most riders, the 500ml size is the sweet spot if you're topping up multiple wheels across the season.
What matters on the bike is that this sealant is designed to work at up to 110psi, seal punctures up to 7mm, and help with porous tyres plus bead-to-rim leaks as well as straightforward tread holes. In independent testing of road-focused sealants, Muc-Off has shown strong performance on small and mid-sized punctures, with competitive sealing up to around 6mm, while the biggest 7mm cuts can still be the point where you may need to stop, add air, or reach for a plug depending on tyre pressure and the size of the damage.
From a buying point of view, this one makes sense if you want higher-pressure compatibility, cleaner valve injection, and a formula that stays practical for regular maintenance rather than race-day-only use. It is also water soluble for easier clean-up, zero ammonia, zero natural latex, and suitable for riders using CO2 on the roadside. In hot Australian conditions, it's worth checking levels regularly and topping up sooner rather than later, especially once temperatures climb well above a mild winter training day.
Road and gravel pressure range
Designed to keep working at up to 110psi, which makes it a much better match for modern road and fast gravel setups than low-pressure-only formulas.
500ml refill bottle
A practical size for home use if you maintain more than one bike, refresh sealant regularly, or want enough on hand for seasonal top-ups.
Seals punctures up to 7mm
Built to handle everyday punctures and larger cuts than many road-oriented sealants claim, helping reduce mid-ride tube installs.
Through-valve application
Can be added through a Presta valve stem or directly into the tyre, so topping up is quick and less messy.
Helps with porous tyres and bead leaks
Not just for punctures — it also helps seal small casing leaks and bead-to-rim gaps during setup and after tyre changes.
CO2 compatible
A good match for riders who carry a cartridge on the road or gravel bike and want roadside inflation compatibility.
Water-soluble clean-up
If you spill it during setup, it washes off with water, which makes home workshop jobs less painful.
Zero ammonia, zero natural latex
A synthetic, water-based formula that avoids ammonia and natural latex while still targeting fast sealing for tubeless systems.

Care
Advanced synthetic latex
We use an advanced synthetic latex formula to create a fast-acting seal that’s tuned for higher-pressure road and gravel riding.
Biodegradable mineral flakes
These biodegradable particles help plug larger cuts quickly, so you can keep rolling instead of stopping at the roadside.
Bamboo fibre sealant particles
Bamboo fibres boost the sealant’s ability to bridge and close bigger holes fast, while using more eco-conscious materials.
Advanced polymers
Advanced polymers help the sealant spread across the inside of the tyre wall for more even coverage and more reliable puncture protection.
Project Green
This product is part of Project Green, with refill bottle options and biodegradable sealing particles to help cut waste while you keep your tubeless setup topped up.
Great for
Maybe not for
Recommended fill volumes are 40-50ml for 23c-25c road tyres, 50-60ml for 28c road tyres, and 70-80ml for 30c-45c gravel tyres, with up to 20ml extra for added protection. This sealant is intended for tubeless road, gravel and CX tyres and is not recommended for non-tubeless setups. You can install it through a Presta valve stem or directly into the tyre. In hot, dry Australian climates above 35°C, check and top up more often.
vs Orange Seal Endurance Sealant
Orange Seal Endurance is the rival for riders who care most about stretching the interval between top-ups. It claims larger puncture sealing and longer service life, while Muc-Off is the more purpose-built pick for road and gravel riders wanting a formula explicitly aimed at higher pressures up to 110psi and easy Presta-valve application.
vs Stan’s Original Tubeless Sealant
Stan’s Original remains a benchmark general-purpose sealant and is easy to inject through the valve, but it is positioned as an all-round formula rather than a road/gravel-specific one. Muc-Off suits riders who want a sealant tailored to faster, higher-pressure tyres and a more explicit road/gravel use case.
vs SILCA Ultimate Tubeless Sealant
SILCA is the premium comparison if you want maximum sealing ambition and very long service life in one package. Muc-Off is the more approachable choice for riders who want a cleaner, more conventional through-valve setup and a formula squarely pitched at normal road and gravel maintenance.
Best use case: modern road and gravel tubeless
This is the version to choose if your bike spends most of its life on 23c to 45c tubeless tyres and you want a formula aimed at those pressures rather than a generic MTB-first sealant.
Carry plugs for the worst cuts
The up to 7mm claim is strong for this category, but on a bigger slash or a hole that opens under pressure, a tubeless plug is still the smart backup for road and gravel riding.
Hot-weather top-ups matter
In Australian summer conditions, sealant dries faster. If you're riding in hot, dry weather, check levels more often instead of waiting for a problem to show up mid-ride.
Valve injection keeps maintenance simple
Being able to add sealant through a Presta valve stem makes routine top-ups much easier, especially on road wheels where you may not want to unseat a tight tubeless bead every time.
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.
