Extend your sewer hose reach or repair a damaged coupling without replacing the whole hose. The Camco 39203 internal sewer hose coupler slides inside the ends of two standard 3-inch RV sewer hoses to create a quick, secure, airtight connection -- no tools required. Black ABS plastic construction, compact enough to store right inside your 4-inch hollow bumper.
Every RV owner eventually hits the same problem: the dump station is just a few feet too far away, or a hose end gets cracked and the threads no longer seal. The Camco 39203 solves both issues with one simple slip-fit coupler. Push it into the open ends of two standard 3-inch sewer hoses and you have a solid, non-restrictive, airtight joint that holds up to 50 PSI working pressure.
Unlike external couplers that add bulk and can snag on the ground, this internal design keeps the outside profile of your hose smooth and consistent. The coupler stores neatly inside your hose coil or in a standard 4-inch hollow bumper, so it is always on hand when you need it.
Inserts inside both hose ends for a flush, snag-free exterior profile. No external clamps or fittings to catch on pavement.
Full 2-25/32 inch inside diameter keeps flow unrestricted. Airtight seal prevents odor escape at the joint.
Use to extend hose length for long-reach dump stations, or to splice out a damaged coupling and salvage an otherwise good hose.
At just over 3 inches long and 3 inches OD, this coupler stores inside any standard 4-inch hollow RV bumper alongside your hose.
The Camco 39203 coupler is designed for standard 3-inch diameter RV sewer hoses -- the same size used by the vast majority of Class A, Class C, fifth-wheel, and travel trailer applications. It works with Camco RhinoFLEX hoses, Camco 20-foot and 15-foot extension hoses, and virtually any other brand that uses the standard 3-inch sewer hose diameter and bayonet-style end fittings.
A cracked or stripped hose end fitting does not mean the whole hose is trash. The 39203 lets you cut off the damaged end and use the internal coupler to rejoin usable hose sections. Combined with a replacement end cap or elbow fitting, you can restore a hose for a fraction of the cost of a new one.
Full-timers and frequent travelers know that losing small fittings is a constant frustration. Because the 39203 fits inside your existing 4-inch bumper storage tube alongside your folded hose, it stays with your sewer kit instead of rattling around a junk drawer. Rinse it off, fold the hose around it, and stow it -- done.
