One adapter that actually fits the dump station in front of you. The Camco RhinoFLEX 72-0712 combines a clear 360-degree swivel elbow with a 4-in-1 adapter that locks into four common sewer inlet sizes -- no guessing, no leaks, no odor.
Dump stations are not standardized, and most RVers have been caught at a station where their adapter just doesn't fit. The RhinoFLEX 72-0712 eliminates that problem. Its 4-in-1 base adapter seats securely into 3-inch, 3.5-inch, 4-inch, and 3-inch slip sewer inlets, covering the vast majority of dump stations found at campgrounds, RV parks, and public dump facilities across North America.
The clear elbow section threads on via a bayonet fitting that rotates a full 360 degrees, so you can orient the hose connection in any direction without kinking your sewer hose or fighting an awkward angle. A built-in gasket at the adapter base creates an odor-tight seal -- no raw sewage smell backing up through a loose connection.
Fits 3", 3.5", 4", and 3" slip dump station inlets -- the four most common sizes at North American RV dump facilities.
Clear elbow rotates a full 360 degrees on its bayonet mount, letting you align the hose outlet to any angle without repositioning the adapter.
Built-in gasket seals against the dump station inlet to block sewer gases and prevent blowback during the dump cycle.
The elbow section separates from the 4-in-1 adapter base and slides into a standard 4" hollow RV bumper for compact, always-ready storage.
The swivel elbow uses a standard bayonet lug fitting, making it compatible with Camco RhinoFLEX sewer hoses and any other sewer hose equipped with a standard lug-style bayonet end. If you are already running a RhinoFLEX hose system, this adapter connects directly without any additional couplers.
Most Class A, Class C, and fifth-wheel RVs have a hollow rear bumper with a 4-inch interior opening. The detachable elbow on the 72-0712 is sized to slip inside that bumper, keeping it protected from road debris and UV exposure between uses. The 4-in-1 adapter base can be stored in your sewer kit bag or hose carrier.
