Stans Original Sealant - 500 ml | Tubeless Sealant

Stans Original Sealant is world-renowned for its advanced latex-based formula that works lightning-fast when a puncture occurs. In the event of a puncture, the air pressure in the tire will force the thin, low-viscosity liquid toward the hole, where the active latex particles instantly clump together to form a permanent plug. This product is designed to effectively seal holes and tears up to 6 millimeters, often occurring so quickly that the rider does not even notice the puncture until the ride is over. The liquid is developed to distribute evenly on the inside of the tire and cover the entire casing, ensuring that all potential leakage points are protected. Because the formula is so free-flowing, it can penetrate even the smallest pores in tubeless ready tires and create a completely airtight barrier. This allows cyclists to ride with significantly lower tire pressure than in traditional tube systems, resulting in better grip off-road, higher comfort, and significantly reduced rolling resistance. Whether you ride with high pressure on the road or very low pressure on technical MTB trails, the liquid retains its ability to seal and protect the tire under extreme loads.

Stans Original Sealant is extremely versatile and specifically developed to support all modern tubeless systems across various disciplines. It is the ideal choice for mountain bikes within XC, trail, and enduro, where the risk of punctures from sharp rocks and roots is high. It is also highly popular among gravel riders traveling on varied surfaces, as well as road riders wanting to eliminate the weight and vulnerability of inner tubes. The sealant is fully compatible with all tubeless ready tires and rims, but it can also be used in standard tires if an approved tubeless conversion kit is used. One of the great advantages of this specific 500 ml bottle is that the amount is sufficient for several bikes or repeated refills throughout the season. Environmentally, Stans stands out by being free of ammonia and other aggressive chemicals, making the sealant biodegradable and gentle on tires, rims, and hands. Furthermore, the formula contains anti-freeze, making it operational in extreme cold down to minus 28 degrees Celsius. This makes the product perfect for year-round riding in the Scandinavian climate, where low winter temperatures would otherwise cause many other sealants to freeze or lose their effective properties.

To achieve the best protection, Stans recommends checking the amount of liquid sealant in the tires every 2 to 6 months. Longevity depends on factors such as the local climate, storage conditions, and how often the tires are inflated. In very hot and dry environments, the liquid can evaporate faster, while in cooler surroundings, it can often remain active for up to 7 months. Installation is made incredibly simple to accommodate both professional mechanics and DIY riders. You can either pour the correct amount of liquid directly into the tire before mounting the last part of the tire bead onto the rim, or you can inject it through the valve using an injector after the valve core is removed. It is crucial to shake the bottle thoroughly before each use to ensure that the active sealing particles are evenly distributed in the liquid. The 500 ml bottle is a practical size, as a typical MTB refill requires around 60-90 ml per tire, while road tires often require less. By regularly inspecting your tires and ensuring that liquid sealant is always present, you minimize the risk of being stranded with a puncture that cannot be sealed. Stans Original Sealant has been tested through millions of kilometers by riders worldwide and remains the preferred solution for those who want a trouble-free and safe riding experience regardless of terrain.
