I have presta valves on two of my bikes. I have a presta floor pump. I have an air compressor. I have a schrader adapter. I have a blowgun and a tire inflator for my compressor. I can attach the blowgun and the tire inflator to the presta valve using the schrader adapter.
What I want to know is what kind of attachment do I need to screw my air compressor on to the presta valve after the core is removed? The schrader adapter screws onto the valve core, so without the valve core, none of my attachments fit. What do I need?
This post indicates that people remove the valve core to get a high volume of air into the tire (which I want to do to seat my tubeless bead), but nowhere can I find exactly how to attach my air to the valve without the core installed.
The only things I can find in videos that actually claim to do this are the Park Tool INF-2 Inflator and the Silca Hiro Locking Chuck, which exceed $150 CAD ($115 USD) and $90 CAD ($65 USD), respectively.
Please help, I've wasted hours trying to get a solid answer to this question.
