Have used all the other disconnects available and without doubt these are the best to date, slip on and off the kegs very easily.

Having problems with both the gas and liquid connects leaking, back to John Guest for me.
Robert Neale –
Hey Ian, Sorry for any issues. We have found with these disconnect that if the tubing is not pushed full home, or the ends are not cut completely square they can leak.
I have sent an email for you.

Rob’s advice fixed the issues I had, compared with the John Guest ones they need a really firm push home as they sort of bite and then a second shove seats them fully. After that they seem fine.
