It was my fault for the confusion. I was thinking of the regular Mya autoseal adapters so when he described his, it didn't sound right. His pictures cleared everything up.
I'm pretty sure both stem ports on the QT are threaded just like the larger Myas. I can't imagine Mya would use a different size thread on the QT (M10x1.0) so it may be possible to unscrew the purge valve stem and use the regular autoseal adapter. I don't have a QT so I can't verify this myself.
