Road- and gravel-specific tubeless sealant for higher pressures, easy top-ups and clean workshop use.

If you're running tubeless on a road or gravel bike, this is the Muc-Off formula aimed squarely at higher-pressure tyres rather than a one-sealant-fits-all approach. The 500ml bottle is the practical refill size for home mechanics and regular riders, with through-valve application, CO2 compatibility, and sealing support for everyday punctures plus bigger cuts when luck runs out.

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.
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.
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.

Muc-Off
Every detail as listed by the manufacturer.
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.
