Collection: Sealant Funnels for filling tubeless bicycle tires

Had a chance to use it a few days after I got it on a tire mounted with a liner. When the flow down the funnel stopped, I pinched the tire a bit to squeeze some bubbles up through the funnel and it sucked all the sealant into the tire. Less mess/waste than using a syringe!

Such a simple problem solver that works great. Seems well made and durable. Excellent product.

This funnel makes setting up and refreshing sealant in tires a very easy process. Remove valve core, screw on funnel, add desired amount of sealant and replace valve core. Super easy! I have two- one for the work bench and one for the travel tool box. The bright green color makes it super easy to find on the bench or in the tool box.

This is such a simple solution for adding sealant, much easier than an injector and completely mess free, no sealant all over my hands! Easy setup, easy cleaning, I would recommend this for any cyclist.
