Okay, I found a short post on my venting setup - just going to copy it here instead of trying to find the link again:
We got this setup at Lowes I think. There are lots of different styles available. Just look in the dryer hose section at any hardware store.
Talked to hubs and he actually adapted that Quick Connect by screwing it into the vent flange in the acrylic panel and filling the gap with clear silicone caulk to create a seal…it wasn’t designed to fit tightly originally.
On the other hand, it’s a leak proof seal, so I’d recommend anyone having issues to give the caulk a try. (Oh, and we used a worm clamp up at the top, not the little spring ones that come with the unit.)
