Stan’s Original Sealant – 500 ml

The most reliable tubeless fluid on the market – for riders who demand performance and trouble-free riding.

When you ride tubeless, you know that the quality of your fluid can be the difference between continuing your ride or being stuck at the roadside. Stan’s Original Sealant – 500 ml is the original, thoroughly tested formula that has set the standard for tubeless technology for over a decade. It delivers fast sealing, long durability, and reliable puncture protection – whether you're mountain biking, gravel riding, or road cycling.

Tubeless fluid that works – every time

Stan's is the pioneer in tubeless fluid, and their Original Sealant is known for its ability to seal punctures in an instant. The advanced latex-based formula effectively seals small holes up to 6 mm in seconds and stays in the tire for months at a time.

This tubeless ready solution is designed to work at both low and high tire pressures, and it remains liquid longer than many competing products. This means fewer maintenance tasks, fewer punctures, and more trouble-free kilometers on the bike.

Optimal protection for all types of bikes

Whether you ride XC, enduro, gravel, or road, Stan’s Original Sealant – 500 ml gives you the security and flexibility you need. It works in all tubeless ready tires and can also be used in regular tires with a tubeless conversion kit.

For MTB riders, it means peace of mind on rocky trails. For gravel riders, it means fewer stops on long rides. And for road cyclists, it means pure efficiency and speed – without fear of punctures.

Easy to use and maintain

With Stan’s Original Sealant, you get a tubeless fluid that is as practical as it is effective. The 500 ml bottle is ideal for riders who cycle a lot or have multiple bikes. The large quantity makes it easy to maintain your tires throughout the season.

Pour the fluid directly through the valve (with the valve core removed) or directly into the tire during installation. Shake the bottle before use, and you're ready to ride. Stan's recommends checking and refilling every 2–6 months depending on temperature and riding conditions.

Tubeless ready – ready for racing and adventure

Stan’s Original Sealant – 500 ml is developed to complement all modern tubeless ready systems. It ensures a tight and stable seal between tire and rim, allowing you to ride with lower tire pressure, better grip, and increased comfort – without compromising on speed or durability.

It's the same fluid that professional riders worldwide use for both racing and extreme terrain. A proven product that delivers – regardless of the weather and terrain.

Environmentally friendly and efficient

Stan’s Original Sealant is free of ammonia and aggressive chemicals, making it gentler on both tires and rims. At the same time, it is biodegradable, so you can choose performance without compromising the environment.

The latex-based formula maintains its effectiveness over time and requires no special tools or maintenance procedures – just a simple refill system and regular checks.
