• 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.

• 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.

• 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.

How does the Sealant Funnel Core+ work to add tubeless sealant?
Remove the valve core with the integrated remover, thread the funnel onto the Presta valve, compress the tire slightly, pour sealant into the funnel, then release the tire. The tire's expansion creates suction that pulls the sealant through the valve. The threaded connection seals at the valve once fully seated, resulting in virtually no mess.

How does the Sealant Funnel Core+ compare to using a syringe-style tubeless sealant tool?
Syringe-style tools require you to push sealant through the valve under pressure using a plunger and often need hoses or adapters. The Sealant Funnel Core+ eliminates those components entirely, the tire's own compression and expansion draws the sealant in passively. It also doubles as a valve core remover, replacing a second separate tool.

Which tubeless valve types and bike disciplines is the Sealant Funnel Core+ compatible with?
The Sealant Funnel Core+ fits standard Presta valves and is compatible with road, gravel, XC, trail, enduro, and downhill tubeless systems. A Fillmore-compatible version is currently in development. It is not compatible with Fillmore valves yet, and is not recommended for yogurt-style or extremely chunky sealants.

Does Shockwave Parts ship the Sealant Funnel Core+ to Canada, and what are the shipping costs?
Yes, Shockwave Parts ships from Canada. Tracked shipping within Canada starts at $8.49 CAD with a maximum of $14.99 CAD, and orders over $89 CAD qualify for free shipping. The Sealant Funnel Core+ is priced at $21.49 CAD and is currently in stock.

How much sealant does the Sealant Funnel Core+ hold per fill, and how many fills are needed for different bike types?
Road bikes typically require one funnel fill. XC bikes usually need around two fills. Trail, enduro, and downhill setups generally require two to three fills depending on tire size and sealant volume. For repeated fills, place a rag over the funnel opening while compressing the tire, refill the funnel, then release to draw in another dose.
