Camco RhinoFlex Clear RV Sewer Hose Elbow with 4-in-1 Adapter

The RhinoFlex Clear RV Sewer Hose Elbow from Camco features a 360-degree rotation and a built-in gasket for an odor-tight seal between the hose and dump station. The 4-in-1 adapter accommodates four inlet sizes—4″ NPT, 3 ½” NPT, 3″ NPT, and 3″ slip fittings—making it versatile for varied campground hookups. A transparent elbow lets you confirm when drainage is complete, reducing guesswork and potential messes. This connector is designed to prevent leaks and keep odors contained during the dumping process.
Features include odor-tight secure connection, versatile adapter compatibility across common inlet sizes, and transparent construction to visually verify drainage. The combination helps simplify waste disposal at many parks, especially when station configurations vary. For RV owners, this fitting offers a reliable, long-lasting option to minimize odors during disposal and improve overall campsite hygiene.
Camco RhinoFLEX Camper/RV Wye Sewer Hose Fitting

This RhinoFLEX Wye Fitting by Camco enables connecting two sewer hoses to a single dump station. It uses 360-degree swivel ends with two bayonet fittings and a lug fitting, allowing flexible alignment and easy connections from multiple directions. Built-in gaskets ensure an odor-tight seal, preventing smells from escaping during disposal. The design supports straightforward, multi-hose configurations while maintaining secure attachment to both hoses and the dump inlet.
Considerations include compatibility with standard hose diameters, ease of rotation in tight campsites, and maintaining an odor-tight connection when multiple hoses are used. This accessory is ideal for RV owners who frequently travel with a second hose for longer dumps or who camp with other RVs sharing one dump station. The swivel action minimizes kinking and strain on waste hoses.
Camco RhinoFLEX Clear 90-Degree Camper/RV Sewer Hose Swivel Fitting

The RhinoFLEX Clear 90-Degree Swivel Fitting features a swivel lug fitting and a bayonet fitting to secure connections quickly. The 90-degree design helps when the RV’s outlet is positioned awkwardly, enabling a smooth, twist-free path for the hose. The clear construction allows you to monitor the flow, ensuring the black and gray water tanks are properly emptied. Durable UV-stabilized resin contributes to long service life in outdoor environments.
Key considerations include ease of installation, visibility of flow, and secure connections that resist leaks. This fitting is well-suited for spaces where direct hose routing is hindered by structure or terrain, offering a reliable solution for better control and hygiene during sludge disposal.
Camco Clear RV Sewage Hose Adapter

The Clear RV Sewage Hose Adapter extends the hose outlet by about 5 inches, providing extra reach in tight spaces. Its transparent design lets you monitor when the system is fully rinsed, aiding in a cleaner and more efficient process. It uses bayonet connections on the RV outlet and lug fittings to attach to the sewer hose, enabling straightforward and reliable hookups.
Considerations include the added length for clearance in cramped campsites and the durability of the clear material under UV exposure. This adapter is a practical upgrade for RVers who frequently need a longer, see-through connection to confirm complete rinsing before stowing the hose.
Combo Pack 2-Piece RV Sewer Hose Fitting Adapters

This TonGass combo pack includes a rotating rigid pipe adapter and a termination adapter, designed to simplify connections between the sewer outlet and a 3-inch pipe or hose. The rotating adapter reduces twisting and strain on the main hose, while the termination adapter provides a secure, compatible end for various setups. Both pieces align with standard 3-inch hub and bayonet hook configurations, and they are built to OEM specifications for durable performance in outdoor environments.
Key considerations include the versatility of the 3-inch bayonet hooks, compatibility with damaged threads, and the overall ease of use when connecting to different sewer infrastructures. The combo pack is especially useful for RV owners who frequently adapt to diverse dump station configurations or need quick, reliable connections on the road.
Buying Guide: Key Purchase Considerations
When selecting RV sewer hose fittings, consider compatibility, durability, and ease of use across different campground setups. Important factors include:
- Inlet compatibility: Ensure adapters fit standard dump station inlets (3″ bayonet, 3″ slip, 4″ NPT, etc.) and that they cover both male and female configurations.
- Connection tightness: Look for built-in gaskets, bayonet and lug fittings, and 360-degree swivels to prevent leaks and simplify alignment.
- Visibility: Clear fittings let you monitor flow and confirm complete rinsing, reducing guesswork and odors.
- Durability: UV-stable resins and corrosion-resistant hardware extend service life in outdoor environments.
- Ease of use: Swivel ends and rotating adapters minimize hose twisting, which protects hose integrity and makes setups faster.
- Versatility: 4-in-1 adapters or combo packs help accommodate multiple inlet sizes and damaged threads for broader campground compatibility.
For practical use, pair high-quality adapters with odor-tight seals and reliable hose connections. Prioritize products that balance a secure fit with the flexibility to accommodate both single-hose and two-hose configurations, depending on your camping style and campground rules.
