Got a 2024 model year bike recently and it came with this valve that I haven’t worked with before. I want to add sealant to my tire but there’s no core to take out like in a traditional presta valve. What do?

Reserve Fillmore valve. It’s basically all valve core.
Pop the bead and dump it in
Unseat the tire, pour some sealant in, reseat the tire.
Use a valve core removal tool to remove the valve core.
I’ve just hooked the syringe up and shot it in. These valves are designed to help make tubeless setup easier by increasing the rate you can add air with an air compressor. There may be consequences down the road if the valve gets gummed up. I have had this issue yet though
If you can’t remove the core, you need to remove a portion of the tire from the rim and pour directly into the tire.
Silca has a good write up on it. https://silca.cc/blogs/silca/tubeless-sealant-installation
It looks like fillmore valves. If you want to add sealant with fiber (like silica one), you should only add directly to tyre. Liquid only sealant should be ok.
Most sealants that aren’t insanely aggressive (e.g. Silca Ultimate) can be injected straight through the valve as long as your injector fits around the valve.
That said, it’s still safer to pop the bead and pour the sealant into the tire.

You can just dump sealant in through the valve, remove the presta adapter on the typical syringe and basically use your syringe like a funnel.
Or you can break the bead and dump it for a much faster method.
Just squirt it through the valve and it will be fine.
Source: my Fillmore valves aren’t clogged.
I set these up by using a small piece of aquarium tubing to connect the squeeze bottle of Stan’s to the valve stem, then just squirted the sealant in. Worked great, no issues with clogging yet.
I run fillmores on my tubeless setup. Orange sealant straight down the valve.
Their airflow is great for seating tires with my wimpy compressor. I swear by em. Never had a clog either.
These are premium Fillmore valves. They don’t get plugged with sealant. Just pop the bead and dump it in.
