This adapter connects 2 pipes that move waste outside of your RV or motor home. The 1-1/2" hub slides onto a sewer system pipe, and the female NPT end threads onto a sewer system pipe.
WOW! I am impressed! I called to place my order and real person answered, spoke perfect English, albeit a slight southern accent, and my order was sent within a day, shipped quickly and I had it a few days later. I saved over a hundred dollars over local and installed it my self. I cant imagine how that they could do any better. THANKS!
