Review: Works great! - I use this to connect my old 5.1" AC duct to my new AC with a 5.9" duct. I had to remove the existing connectors on the ends of the new and old ducts before attaching the adapter. Then I screwed the 2 ducts into the adapter. I've been running the AC all afternoon with no issues. The adapter stays connected and there is no air escaping from the adapter. Trust me, I'm not the least bit mechanically inclined but I got it to work just fine. Review: Works great - I have 2 of these and was able to extend the ac way out into the room, 16 feet from the window if I need to. I haven't tried the OD, just the inside so far ## Features - Universal 4-in-1 Vent Hose Connector: This portable ac hose coupler can fit any 5.1"/5.9" hoses with clockwise or counterclockwise thread, the internal interface for 5.1 inch hose , external for 5.9 inch hose.
