The QC4 system on a Meg is NOT manufactured by Swagelok. The actual male quill made by Swagelok is somewhat different, being that the internal (pin) and collet are integral, not like the one ISC supplies as stock. I had problems with my male QC4 from new, and have since replaced it with the ACTUAL Swagelok item. The Male QC 4 from Swagelok is 100% interchangeable with the ISC item, and I have confirmed that the female connector need not be replaced to correct the leaking.
Be careful with the Swag item as I don't think they have gone through the passivation process. That's probably why ISC went with the QC4 they currently provide.
