Stop buying pieces separately. The Camco 39672 SuperKit ships as a ready-to-use sewer system for RVs and motorhomes with both a black-water and a gray-water holding tank outlet. Two 10 ft hoses connect end-to-end for 20 ft of total reach, a translucent wye fitting handles the dual-tank split, and the included 4-in-1 adapter covers the most common dump-station inlet sizes -- all in one box.
Most RV sewer kits require you to hunt down the wye fitting or the right adapter separately. The 39672 SuperKit solves that by bundling every component into one part number. The translucent wye fitting lets you see flow from each tank outlet so you know when the line is clear before capping up. Storage caps keep the fittings odor-free between trips.
Each hose section is reinforced with a steel wire spine that holds its shape on uneven ground and resists crushing when stored in a typical bumper tube. The swivel fittings on each hose end rotate to align with angled inlet collars without twisting the hose body -- a small detail that makes real-life hookup significantly faster.
Two 10 ft sections join together -- extend one or both to suit your site layout.
See-through body shows active flow from each tank outlet so you know when tanks are clear.
Clear elbow adapter fits the four most common dump-station collar sizes -- no separate adapter needed.
Rotating bayonet-style fittings align to angled dump inlets without twisting or kinking the hose.
Every component required for a dual-tank sewer hookup is included. Nothing extra is required for standard campground and dump-station use:
Both the wye fitting and the elbow adapter are made from a clear or semi-clear material so you can watch waste flow through the line. This lets you confirm the tank is empty and the line is fully flushed before you disconnect -- a genuine sanitation and odor-control advantage over opaque systems.
Each 10 ft hose section uses a corrugated, steel-wire-reinforced design that is standard to the Camco RhinoFLEX product family. The spiral wire embedded in the hose wall prevents collapse under suction and holds the hose shape when draped across uneven terrain. The outer surface is UV-stabilized to resist cracking from sun exposure during extended outdoor use.
Hose diameter is 3 inches (inner), which is the near-universal standard for RV black and gray-water drain connections. The bayonet-style end fittings are compatible with the standard RV sewer outlet collar found on virtually all North American travel trailers, fifth wheels, and Class A, B, and C motorhomes built after the mid-1980s.
If your RV has only one drain outlet, simply connect one 10 ft hose directly to your tank outlet and attach the second section for extra reach. Use the 4-in-1 adapter elbow on the dump-station end. The wye fitting and one storage cap will remain unused but are handy if you upgrade to a two-tank rig or need a spare fitting later.
The two 10 ft hose sections compress for storage in a standard 4-inch diameter RV bumper tube (bumper not included). Storage caps seal each open end to contain residual odor between uses. The fittings and adapter can be bagged separately or stored in the bumper tube alongside the compressed hoses.
