Just a tip to keep your QC's from leaking:
Put a capped male QC into them when not in use. An open QC can collect dust and the locking mechanism is susceptable to vibration that can cause intermittent leaks. '
Keeps them clean and the connection sealed. It wont vibrate off like a dust cap will.
x2. This was my first thought when I read about others' leaking issues. And, subscribed.
