Presta Valve Tire Sealant Funnel

thingiverse

A compact funnel made for inserting tire sealant into Presta valves is now available. Its entrance measures 40mm in width. Reaching a height of approximately 43mm, this tool ensures the valve's threads are securely caught while its internal lip skillfully guides the material into the inner diameter. Once the valve core has been removed, the funnel's inner opening should be roughly 4.2mm, and the outer threads about 5.8mm in width.
