Scrounging through my bag of plastic push pins, I found one the perfect size to function as a coupler plug, since there's not enough room to fit a dust cap over it.
25.1mm top diameter, 11.2mm barb diameter, 7.1mm shaft diameter, clipped to 13.3mm long (shaft)
I trimmed one row of barbs to allow the ball bearings to clip in easier. A gasket was added to fill the space left between the top lip and coupler. Finally, I clipped the tip so it wouldn't depress the air valve when inserted into the coupler.
