Review on 🔌 Mission Automotive 8-Pack of RV Sewer Hose Replacement Gaskets - Compatible with Camco RhinoFLEX/Revolution - Long-lasting Rubber Seal Fittings by Ted Slaughter

The description says the package contains 4 3-1/2 inch drain gaskets and 4 "knee" gaskets, whatever they are. Well, 4 gaskets for ordinary sewer pipes work great. They fit perfectly and seal well. My drain hose now works like new. But the "elbow joint" pads are useless, so I'm deducting a star. They are slightly smaller in diameter and have a smoother surface than traditional pads. Maybe I should have known better, but I've been riding balance bikes for over 20 years and this is the first time I've encountered a smaller diameter "knee". What I bought it for worked well. I just hate that I now have 4 pads that I can't use because they are too small.
