Camco's RhinoFLEX 15 foot RV Sewer Hose Kit with RhinoFlex Hose and Swivel Fittings is a ready-to-use kit made with the toughest hose you can buy. The sturdy polyolefin is reinforced with steel wire for an ultra-tough hose. It is also collapsible, so you only have to extend as much hose as you need. This kit features a bayonet fitting with four prongs for a more secure fit. At the dump-station end there's a translucent elbow with an easily detachable 4-in-1 adapter for connecting to 3-inch slip or 3-inch, 3-1/2-inch and 4-inch NPT threaded sewer connection. The fittings swivel and feature reusable locking rings so that fittings can be moved to a new RhinoFLEX hose if needed. The kit also includes a storage cap for each end. The hose and fittings compress to 56 inches for storage and once the 4-in-1 adapter is removed you can store the hose in standard 4-inch square bumpers.
