derSchraderFlatter QR - quick release tire deflator for Schrader valves

cults3d

I recently posted my "derSchraderFlatter" Schrader valve deflator - a screw on replacement for a tire valve cap that holds the valve open so the tire can be deflated when needed for service without manually holding it open with a small screwdriver or allen key (hex wrench). Well, no sooner did I start using it did I realize even with reduced threads, it was still too slow to work with, requiring threading on. What about something that would push on and lock in place, easily removable when the tire is flat? Enter derSchraderFlatter - quick release edition. It's about the same size as the original, but simply pushes on at which point the threads on the flexible portion grab onto the threads on the valve, holding it in place. When you're done, press the button on top and it'll quickly release and pull off. What is this used for? I'm working on a bike, there are many things that require removing the tire when it's not already flat. Replacing a worn-out tire, doing service on the wheel, replacing a wheel, or replacing a broken spoke - all of these need the tire to be deflated so it can be removed. I could stand there and hold the valve open until it's completely flat (I've been doing that for years) but having a tool that takes that out of my hands allows me to work on something else while this is happening. I could install this tool and start deflating the tire while starting to remove the wheel. A car mechanic could also use this to deflate a car tire, but in that case there's a whole bunch more air volume so removing the valve core is likely a much faster solution. Note: Yes, this could be used for nefarious purposes by jerks. Don't be a jerk. Update 20 Jan 2020: I'm not good at spelling. It's "Shrader", not "Schraeder". I usually check these things before posting. Oops.
