Patching Small Leak

I noticed some puddling around this PVC pipe going into my HVAC unit the other day. It obviously has been there for some time with the rusting of the screws at the top. I'm hoping I can use something to stop the leak without needing to have a serviceman come and replace everything.

Welcome to the forums.

Are you referring to the large PVC line..... the flue vent or discharge ?
Can you post another picture of the larger area ?

Here's a wider shot of the pipe. It's the one in the front right.

It looks like that 45 should have been a street 45.
It is too large for the connection to the furnace as a female.

It is possible that you may be able to insert a small piece of pipe into the 45 to properly mate with the furnace but I suspect that you may need a coupling, a street 45 and some pipe at this point.

That furnace ships with connectors...
