Sealant

The Next Level in Sealing Power from the People who Invented Tubeless Conversions.

If you've walked the mechanics' pits at any National or International level event, chances are you've seen them: trademark Stan's black quart bottles with no labels. Look closer and you might have seen strange symbols scrawled all over the bottles in a silver marker, letters and numbers, formula notes by the man himself, Stan Koziatek.

The #1 Rated Tire Sealant on the Market. 

The Product that Started a Tubeless Revolution. Inside this small 2 ounce bottle is a product that changed cycling. Today's tubeless systems rely on the lighter, more reliable, self-sealing performance of Stan's Tire Sealant.

Just two ounces of Stan’s Tire Sealant in a converted standard tire or a tubeless tire can repair up to a 1/4” hole instantly. One quart will convert up to 16 tires. Use only 2 ounces for most bicycle tires. Stan’s Tire Sealant will stay ligquid in a mountain bike tire with a thin casing for two to seven months on average. Riding in arid climates or storing the bike in a hot area will require most frequent monitoring of sealant levels. Special anti-freeze agents allow the sealant to be used in environment as cold as -20 F.

The Dual Action Repair for Tubeless (DART) was developed to fix damaged tires faster, easier and better than existing plug tools. While traditional tire plugs try to wedge rubber strips into a puncture, the DART creates a chemical reaction with your Stan’s sealant to quickly form a permanent airtight bond. 

Our Dual Action Repair for Tubeless (DART) system offers a better way to fix damaged tubeless tires. Specially treated DARTs don’t just plug large slices and punctures in your tires, they react with Stan’s sealant to form a permanent airtight bond. This Refill kit contains five DARTs and a carrier that makes reloading your DART Tool fast and easy, all stored in a compact, sealed container.
