Here is an odd twist, i bought most of the parts in this build from one store and they offered some install insurance with all i bought.
Since I didnt want this service i thought i had not asked for it, but it comes included and you need to remove it as an option when paying - i missed this, but i was in a hurry and didnt remove it. I actually meant to get in touch and cancel it but forgot, i checked their email and its on the list, so hopefully i am covered.

I will take a pic before i send it off.

Anyone else using the same fittings with one of these?

Looks like barbs for me otherwise.
