The QC4 system on a Meg is NOT manufactured by Swagelok. ....... 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.
Is there any issue with O2 compatability or is it just a cost issue that has made ISC go with an other manufacturer?
