Camco 39753 RhinoFLEX Sewer Hose Storage Caps, 2-Pack

Anyone who's wrestled with an RV sewer hose knows the worst part isn't the dump itself. It's what comes after. You disconnect, and both ends of that hose are still holding a little residue. Toss it in the storage bay uncapped and you've got drips, smell, and a mess you'll be scrubbing later. The Camco 39753 fixes that with a simple two-cap set, one for each end of your hose, so everything stays sealed up until your next trip.

The set gives you two different caps because your sewer hose has two different ends. One cap fits the bayonet fitting, the lug-style connector that locks onto your RV's waste outlet. The other caps the 4-in-1 elbow, the tapered end that drops into the dump station inlet. Each one presses on and holds an odor-tight seal. No more open hose ends breathing into your storage compartment every time you hit a bump in the road.

These are built to work across Camco's whole Rhino sewer hose lineup. If you're running a RhinoFLEX, a RhinoEXTREME, a Revolution, or an Easy Slip hose, these caps match the fittings. That's genuinely handy if you've swapped hoses over the years or run different setups on different rigs, because you're not stuck hunting for a cap that only fits one specific model. One set covers the fittings you're most likely to have.

Here's the real reason to keep a set on hand. A capped hose is a clean hose bay. Full-timers deal with this every few days, and even weekend campers know the annoyance of pulling out a stored hose that wasn't sealed. Leftover gray and black water sitting in an open hose end doesn't just smell. It drips onto whatever else lives back there, your leveling blocks, your fresh water hose, your tools. Cap both ends and that whole problem goes away.

And it's not only about odor. A sealed hose end is a hygiene thing too. That hose handles black tank waste, and you really don't want an open end resting against gear you touch with bare hands. Capping both ends keeps the dirty parts contained and the clean parts clean. If you store your hose inside the RV rather than in a bumper, that separation matters even more, because there's no sealed compartment between the hose and your living space.

One thing to be clear about. These are caps, not fittings, and not a hose. They don't add a hose connection or replace your bayonet or your elbow. They seal the ends of the fittings you already own. If what you actually need is the 4-in-1 elbow itself or a new bayonet fitting, that's a different part number. This set is purely about sealing your hose ends for storage and travel.

Using them couldn't be simpler. After you dump and give the hose a good rinse, let it drain, then push each cap onto its matching end. The bayonet cap goes over the lugs, the elbow cap slips over the tapered 4-in-1 end. Pull the hose into its bumper tube or storage bay and you're done. On travel days those capped ends also keep road grime, dust, and bugs out of the hose, so you're not starting your next hookup with a filthy connector.

For a two-pack that costs less than lunch on the road, these save you a lot of cleanup and a lot of nose-holding. Keep one set with your hose and stash a spare in the toolbox. When a cap eventually cracks in the cold or wanders off at a campground, and one always does, you'll be glad you had a backup ready to go. At this price, buying two sets at once is an easy call.
