Stan's NoTubes Original Tubeless Sealant vs Orange Seal Endurance Tubeless Tire Sealant
Which should you buy? Our verdict on both, pulled from our full The Best Tubeless Sealants: 4 Compared (and One to Skip) comparison.
Stan's Original wins on published detail and breadth: a stated 6.5mm sealing limit, a 2 to 7 month liquid life, freeze protection to -20F and a dosing chart that covers road through fat bike. Orange Seal Endurance is the better choice if you would rather refill less often and want a measuring dipstick in the box.
Stan's NoTubes Original Tubeless Sealant
Buy itThe sealant everything else gets compared to, and the one that publishes the most numbers.
- Stan's states a 6.5mm maximum puncture size, which is at the top of this group.
- Anti-freezing agents are rated for use down to -20F, the lowest published figure here.
- A full dosing chart covers tire sizes from 700c x 28mm to 26 x 5, so you are not guessing at volume.
- Stan's puts the liquid life at 2 to 7 months, a wide band that shifts with how dry your climate is.
- Stan's notes arid conditions need more frequent level checks, which means a seasonal habit rather than set and forget.
- Valve installation uses Stan's Tubeless Sealant Injector, which is a separate product.
Orange Seal Endurance Tubeless Tire Sealant
Buy itSame sealing claim as the standard formula, built to go up to three times longer between top-offs.
- Orange Seal states the Endurance formula lasts up to three times longer, so you go longer between top-offs.
- The stated sealing limit is punctures up to a quarter of an inch, in line with the strongest claims here.
- The 4oz and 8oz injector bottles ship with a dipstick, so you can check the level without breaking a bead.
- Orange Seal does not publish a low temperature figure, only that it performs across varying temperatures and altitudes.
- The latex type and whether the formula contains ammonia are not stated.
- Refills are sold separately from the injection system bottles, so the first purchase should be an injector bottle.
