• Fits standard Presta valves.
• Compatible with road, gravel, XC, trail, enduro, and downhill tubeless systems.
• Fillmore-compatible version currently in development.

1. Remove the valve core using the integrated remover.
2. Thread the funnel directly onto the valve.
3. Compress the tire slightly.
4. Pour sealant into the funnel.
5. Release the tire to draw the sealant inside.
6. Reinstall the valve core using the same tool.

The funnel threads create a secure seal with the valve. Once the tool bottoms out, the connection is sealed and ready to use with virtually no mess.

The real advantage of Sealant Funnel Core™ is that the tire itself helps pull the sealant inside.

Simply compress the tire slightly with your weight before filling the funnel. When you release the tire, it naturally expands back to shape and creates suction inside the tire.

That suction instantly pulls the sealant through the valve and into the tire.

Instead of forcing sealant through a syringe, the tire effectively becomes the syringe itself.

Most riders are surprised by how quickly the sealant disappears into the tire the first time they try it.

• Compress the tire before filling the funnel, then release it to draw the sealant in.
• For repeated fills, place a rag over the funnel opening while compressing the tire again.
• Refill the funnel and release the tire to pull another dose inside.
  
• After a few uses you'll quickly develop your own preferred filling technique.

Once you get the rhythm, adding sealant becomes incredibly fast.

• Road bikes: Typically one funnel fill.
• XC bikes: Usually around two fills.
• Trail / Enduro / DH: Usually two to three fills depending on tire size and sealant volume.

The large opening and fast flow rate make even high-volume tires quick to service.

• Two tools in one: Funnel and valve-core remover combined.
• Fast: Add sealant in seconds.
• Clean: No syringes, hoses, adapters, or plungers.
• Leak-free: Secure threaded connection to the valve.
• Simple: Easy for beginners and professionals alike.
• Reusable: Rinses clean in seconds.
• Workshop-tested: Perfect for home mechanics and bike shops.

Simply rinse the tool with water after use.

The large internal passage makes cleaning easy and helps prevent dried sealant buildup.

• Always remove the valve core before use.
• Not recommended for yogurt-style or extremely chunky sealants.
• Very thick sealants may flow more slowly through the valve.
• Clean the tool after use to prevent dried sealant buildup.
