Camco’s RhinoFLEX 20-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 two hoses are made of sturdy polyolefin and are reinforced with steel wire. They are collapsible, and you only have to extend as much hose as you need. This kit features bayonet fittings with four prongs for a more secure fit. Included is 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 for storage, and once the 4-in-1 adapter is removed you can store the hose in standard 4-inch square bumpers.
