Heavy-duty 10-foot sewer hose extension with pre-attached REVO swivel lug and bayonet fittings. 18-mil HTS vinyl construction. Compresses for standard 4" square bumper storage. Storage caps included. No tools or clamps needed.
The Camco 39663 SUPERKit is a 10-foot RV sewer hose extension built from 18-mil HTS (high-tensile strength) vinyl — heavier wall construction than standard sewer hoses for improved puncture resistance and durability. It adds 10 feet to the reach of an existing sewer hose setup when the campsite sewer inlet is farther than the primary hose covers.
Both fittings are pre-attached using Camco's REVO swivel design — a swivel lug fitting on one end and a swivel bayonet fitting on the other — so there's no separate assembly, no clamps, and no tools required. The fittings rotate independently of the hose body, which makes connecting and disconnecting cleaner in tight or awkward hookup positions. When not in use, the extension compresses down to fit inside a standard 4" square RV bumper or storage compartment. Hose storage caps are included to keep the ends sealed.

The 39663 connects between your existing sewer hose and the sewer inlet to add 10 feet of reach: RV dump valve → Primary hose → 39663 extension (swivel lug end first) → Sewer inlet (bayonet end) The swivel lug end connects to the bayonet fitting on your primary hose. The swivel bayonet end connects to the sewer inlet or a clear elbow adapter at the dump station. Tip: When finished, remove the hose end from the sewer inlet first, raise it to drain any remaining waste back into the tank side, then disconnect from the primary hose.
