This ready-to-use kit is made with the toughest hose you can buy. 15' RhinoFLEX sewer hose, and pre-attached specially engineered fittings make it even more convenient. At the RV end of the hose, there is a super-tough bayonet fitting with 4 prongs for a more secure fit. The dump-station end includes an easily detachable 4-in-1 adapter for fitting to 3" slip or 3", 3-1/2" and 4" threaded pipe.
