Camco RhinoFLEX RV Sewer Hose Connections, Elbows & Replacement Parts

RV sewer hose connections are easier to assemble and maintain when you know which end uses a bayonet fitting, which uses a lug fitting, and what connects to the dump-station inlet. Camco RhinoFLEX hoses, elbows, adapters, caps and gaskets are sold in several configurations, so it is worth matching the part number and connection style before ordering.

How a RhinoFLEX sewer hose connects

In a typical gravity-drain setup, the hose begins at the RV's waste outlet and ends at the dump-station inlet. The parts between them depend on whether you have a complete hose kit, a bare hose or a separate extension.

RhinoFLEX hoses and extensions

Choose a fitted extension to add reach to an existing compatible sewer hose, or the bare hose when replacing a hose section and supplying separate fittings.

Dump-station elbows and adapters

These fittings serve different installation needs. A 4-in-1 style adapter provides multiple dump-station connection options, while the Adapter PRO uses a flexible expanding gasket for the inlet types identified by Camco. The clear 90-degree elbow is a separate component; identify its ends before pairing it with another fitting.

Replacement gaskets, caps and fitting tools

Worn or missing seals can cause drips at hose connections. Choose the correct gasket shape, and use storage caps made for your particular hose-end fittings.

For a hose with a bayonet end and a fitted elbow rather than a plain lug end, see the Camco 39753 bayonet-and-elbow storage cap set. For a portable waste-tank connection, the Camco 39768 3-ft tote-tank hose kit is a separate, purpose-built hose arrangement.

Choosing the right replacement

1. Check the hose ends. Identify the bayonet and lug fittings already on the hose, or whether an elbow is attached.
2. Match the dump-station opening. The 39736 has a 4-in-1 adapter; Camco specifies the 39730 PRO's flexible gasket for 3½- and 4-inch NPT openings and certain unthreaded or damaged-thread inlets. Those are different designs.
3. Count the pieces. Camco 39834 contains four gaskets (two bayonet, two elbow/4-in-1). Camco 39758 contains two swivel-fitting wrenches. Camco 39752 contains two storage caps (bayonet and lug).
4. Inspect before emptying. Ensure the fittings are secure, the rubber seals are seated, and the dump adapter cannot shift. After dumping, rinse the hose and store it with the appropriate caps.
