Getting the right angle at the dump station sewer inlet is one of those small details that makes a big difference. The Camco RhinoFLEX 90-Degree Swivel Fitting (part 39857) redirects your sewer hose at a right angle to your RV waste valve, reducing strain on the hose and fittings and giving you a cleaner, more controlled connection every time you empty your holding tanks. The clear body lets you confirm flow and see when the tank is fully drained -- no guessing, no mess.
Most RV waste valves exit horizontally or at an awkward angle relative to the sewer inlet at your site or dump station. Running a hose straight out and then trying to bend it down into the inlet puts stress on the hose collar and the valve itself. The 39857 swivel fitting solves this by placing a 90-degree turn right at the valve outlet -- so your hose drops cleanly toward the ground and into the inlet without fighting gravity or kinking.
Both ends swivel independently, which lets you rotate the fitting to align with your specific valve and hose layout without twisting the hose body. This is especially useful at campground pedestals where the inlet angle doesn't match your setup.
See waste flow in real time. The transparent fitting makes it easy to confirm your black or gray tank is fully emptied before disconnecting -- reducing spills and repeat flush cycles.
Compatible with bayonet and lug-style fittings used across Camco RhinoFLEX, Rhino Extreme, Easy Slip, and most other standard RV sewer hose systems.
Integrated gaskets at both ends compress to form a leak-resistant, odor-tight seal without additional tape or adapters. No separate gasket sourcing required.
The resin formula resists UV degradation and cracking in direct sun -- important for a fitting that stays outside during your entire campsite stay.
The 39857 swivel fitting is designed to work with the full Camco RhinoFLEX sewer hose family, including RhinoFLEX, Rhino Extreme, and Easy Slip hoses, as well as any other standard RV sewer hose system that uses the common bayonet or lug collar style. This covers the vast majority of aftermarket and OEM RV sewer hose setups sold in North America.
Fixed 90-degree elbows force you to orient the fitting in one direction. A swivel fitting rotates at the connection point, so you can direct the outlet of the elbow toward the ground, to the side, or at whatever angle your sewer inlet requires -- without torquing the hose or fighting the collar lock. Both ends on the 39857 swivel, giving maximum positioning flexibility.
If you leave your sewer hose connected for extended periods (full hookup sites), a 90-degree fitting at the valve reduces the sagging stress point that develops where the hose exits the valve and bends toward the ground. This extends hose life and keeps the collar from working loose over time.
The integrated gaskets at both connection ends create a compression seal that prevents sewer gas from escaping at the fitting junction. Unlike fittings that rely on the hose collar alone for sealing, the built-in gaskets on the 39857 provide an independent secondary seal -- reducing odor at your connection point even if the hose collar fit isn't perfectly snug.
