Stan's NoTubes Tire Sealant 2 oz Single-Use Bottles — Box of 12, Pre-Measured Valve Injection

Stan's NoTubes Tire Sealant 2-ounce bottles (box of 12) are pre-measured, ready-to-use tire sealant doses designed to stop common bicycle punctures and simplify sealant application.

These 2 oz single-use bottles from Stan's NoTubes give you a convenient, no-mess way to add sealant to a single bicycle tire. Each small bottle contains the correct amount for one tire, fits most valve stems when cores are removed, and is compatible with tubeless setups, inner tubes, and tubular tires. Sold as a box of 12, this pack is ideal for riders who want on-the-spot replacements, service shops stocking parts, or teams preparing for group events.

How do I apply one 2-ounce bottle to my tire?

Application is quick and straightforward: remove the valve core, inject the pre-measured sealant through the valve stem, then reinstall the core and inflate to your desired pressure. If you prefer, you can open the bottle and pour sealant into the tire bead before seating it. No special tools are required beyond a valve core remover and a pump.

• Pre-measured 2 oz dose fits most bicycle tire sizes
• Works through removable valve cores for mess-free injection
• Can be poured directly into tire when preferred
• Reinflate and rotate wheel to spread sealant evenly

What kinds of punctures will this sealant handle?

Stan's NoTubes sealant is formulated to seal small to moderate punctures quickly while you continue riding. It is effective on punctures up to roughly 1/4 inch in diameter for many common road, gravel, and mountain riding situations. Larger gashes or sidewall damage may need a plug, patch, or tire replacement.

• Seals punctures up to approximately 1/4 inch
• Closes holes in tread and small sidewall nicks
• Stops air loss while maintaining normal ride feel
• Pairs with plugs or patches for larger cuts

Is this sealant compatible with my tire and tube setup?

Yes — these bottles are compatible with tubeless tires, inner tubes, and tubular tires. They are pre-measured for a single tire, so dosage is controlled and consistent. When using inner tubes, injecting through the valve stem requires removing the core first; for tubular tires, pour directly if the casing is accessible.

• Compatible with tubeless, tube, and tubular tires
• Designed for valve-core injection or direct pouring
• Small 2 oz volume reduces waste and storage concerns
• Box of 12 gives spare bottles for multiple bikes or events

How should I store and dispose of unused bottles?

Keep sealed bottles at room temperature away from extreme heat to preserve performance. Use bottles within the manufacturer’s recommended shelf life and recycle or dispose of empty containers according to local regulations. Avoid ingesting sealant and keep out of reach of children and pets.

• Store in a cool, dry place out of direct sunlight
• Follow local rules for recycling or disposal of plastics
• Use within suggested shelf-life for best results
• Keep away from children and animals
