I used the portable AC exhaust fittings. They worked perfect. (not just for RVs.) I used them in a Mobile Home. (raised wood floor). It would be nice if you made something similar for the drain lines on portable ac units. (1/2" hose). I looked everywhere. No bulkhead type fittings for thick floors/walls (1.5")
The parts you make are very good quality and function. I will be watching for more.

Ordered the 6 inch type G vent kit so that I could vent a portable air conditioner through my garage door. Intulon was the only company offering anything quite like this. My order arrived within a week. I originally thought it was a bit expensive, but once seeing the design and quality construction I was very impressed. Worked perfectly for my application.

They answered my questioned before my purchase, my order came quickly and beautifully packaged. The product fit my hose and attached easily. it even came with screws needed to attach the ring to the wall. The magnets are STRONG. great product!
