2015 Yukon heater hose leak

[DrUncleIvy]

I have a very slow leak at a heater hose - HVAC hose connector junction near the firewall.
2 questions:
1. What are the part numbers for the HVAC hose connectors (inlet & outlet)? I'm going crazy trying to find them and coming up empty.
2. Is there a metal substitute to avoid dealing w these plastic connectors?
Thanks!

I have the same issue as Dr Uncle Ivy. I have a 2015 Yukon with the 5.3 Liter. My WHITE connector is leaking. The black one is fine. I'm not sure if the white one is inlet or outlet. I can't find the connector for sale any place. I tried GM Parts Direct as Joseph suggested but they only sell the hoses, not the connectors. Similar to Rock Auto and generic parts dealers.
