We started with a 15´ RhinoFLEX sewer hose, and pre-attached specially engineered fittings to make it even more convenient for you. At the RV end of the hose, there is a super-tough bayonet fitting with 4 bayonets for a more secure fit. At the dump-station end we´ve added a translucent elbow that separates from the 4-in-1 adapter for easy storage. All swivel fittings feature locking rings to stay secured to the hose. Bayonet cap and elbow cap also included. Patent pending.
