Camco RhinoFLEX Elbow 4 In 1 Adapter w/Swivel Bayonet Fitting 
RhinoFLEX Elbow & 4 In 1 Adapter with Swivel Bayonet Fitting
Camco's RhinoFLEX Elbow and 4-in-1 Adapter with Swivel Bayonet Fitting makes it easier to connect to dump stations. It fits securely into four sizes of dump station inlets: 4-inch NPT, 3. 5-inch NPT, 3-inch NPT, and 3-inch slip fitting. The elbow is clear, so you can see when your sewer hose is completely done draining. It has a built-in gasket for an odor-tight connection. The swivel bayonet fitting makes the elbow compatible with any lug fitting and allows it to rotate 360 degrees, making it easy to connect. For storage, the elbow detaches from the 4-in-1 adapter and fits into a 4-inch square RV bumper.
