The Benchmark for Tubeless Performance

Stan's NoTubes Original Sealant is the industry standard for tubeless conversion and maintenance. Formulated over two decades ago and still the top choice for riders worldwide, this 1000ml (1 Litre) bottle is the economical choice for home mechanics and riders with multiple wheelsets, providing enough sealant for up to 16 tires.

The formula uses a very thin, low-viscosity liquid that quickly coats the tire's interior and carries specially formulated sealing crystals to the site of a puncture. Because it remains liquid for a long period, it provides "set-it-and-forget-it" protection that keeps you riding instead of fixing flats on the side of the trail.

Key Features:

• Instant Sealing: Rapidly plugs punctures and cuts up to 6.5mm (1/4") in size using a proprietary mix of natural latex and sealing crystals.

• Long-Lasting Protection: Remains liquid inside tires for 2–7 months on average, though arid climates may require more frequent top-ups.

• Extreme Temperature Range: Includes anti-freezing agents that allow the sealant to perform in temperatures as low as -28°C (-20°F).

• Eco-Friendly Formula: Made from natural materials, this non-hazardous and non-toxic sealant is safe for both the rider and the environment.

• Versatile Application: Fully compatible with tubeless road, gravel, and mountain bike tires, and can be easily injected through valve stems with removable cores.
