Camco"s RV RhinoFLEX Sewer Hose Kit with 15" Hose and Swivel Fittings features a super tough bayonet fitting with four prongs for a more secure fit. At the dump-station end we"ve added an easily detachable 4-in-1 translucent elbow adapter for fitting to 3 inch slip or 3 inch, 3-1/2 inch and 4 inch threaded pipes. It"s a ready-to-use kit made with the toughest hose you can buy. The fittings swivel and feature reusable locking rings so that fittings can be moved to a new RhinoFLEX hose. It includes a bayonet and elbow storage cap. The kit compresses to 56 inches for storage and the removable 4-in-1 adapter allows you to store the hose in 4” square bumpers.”
