Stan’s Original Tubeless Sealant, 250 ml: the world’s first tubeless sealant, for every tubeless road, gravel and mountain bike tyre.
- Seals punctures up to 6.5 mm (¼″)
- Stays liquid in the tyre for 2–7 months
- 250 ml covers one mountain bike (2 × 29 × 2.4″)
Stan’s Original Tubeless Sealant is the world’s first tubeless sealant, formulated by Stan’s founder in 2001 and still the number-one choice of riders today. It works in every tubeless road, gravel and mountain bike tyre, sealing punctures up to 6.5 mm as you ride and staying liquid for 2–7 months.
In the UAE’s heat and dry air, check your sealant more often: Stan’s notes that arid conditions can shorten how long it stays liquid. This 250 ml bottle covers both tyres of a typical 29 × 2.4″ mountain bike, or four 700 × 28 mm road tyres.
How much do I need?
- A 29 × 2.4″ MTB tyre takes about 110 ml, so this 250 ml bottle is enough for one mountain bike.
- A 700 × 28 mm road tyre takes about 50 ml, so one bottle fills four road tyres; a 700 × 40 mm gravel tyre takes about 60 ml.
- Shake the bottle well before use. Valves with a removable core let you top up without taking the tyre off.

Why riders choose it
- Seals punctures up to 6.5 mm (¼″).
- Stays liquid for 2–7 months inside the tyre.
- Anti-freeze agents keep it working down to −20 °F (about −29 °C).
- Fits any tubeless tyre: road, gravel and mountain bike.
- Pour or inject: pour it straight into the tyre, or inject it through the valve with Stan’s Tubeless Sealant Injector.
- Economical: Stan’s says one litre seals up to 16 tyres.

Questions people ask
How often should I top up?
Stan’s Original stays liquid inside the tyre for 2–7 months. Stan’s advises checking the level more often in arid conditions, so in the UAE’s heat and dry air, check it regularly and top up when it runs low.
How much sealant does my tyre need?
About 50 ml for a 700 × 28 mm road tyre, 60 ml for a 700 × 40 mm gravel tyre and 105–110 ml for a 29 × 2.3–2.4″ MTB tyre. The full chart is above.
What size of hole will it seal?
Stan’s Original seals punctures up to 6.5 mm (¼″).
Can I add it through the valve?
Yes. With a valve that has a removable core you can inject it using Stan’s Tubeless Sealant Injector, without unseating the tyre.
Does it work with any tubeless tyre?
Yes. Stan’s recommends it for all-round use in all tubeless road, gravel and mountain bike tyres.
How should I store it?
In a cool, dry place out of direct sunlight, with the cap closed. Avoid extreme heat, such as a car parked in the sun.
