Ok, so I'm working on a 2014 Sonic LT 1.8L. just preplaced the condesor and she (my cousin) had the hoses replaced a couple of moths ago. My problem is, there is a leak right at the evaporator tube and hose connection. I'm at a loss as to why though. The seals are brand new and purchased from the auto parts store, specifically for his vehicle. I made sure to coat the new seals with refrigerant oil before re connecting them. Nut is right and the metal hose connections are seated straight and (Seemingly) flush. Yet, the leak is still happening. I witnessed it in real time with my UV light, so I know exactly where it's coming from. Please someone help me !!

Here's he culprit

It seems to be coming from this connection specifically
