RV Tank Fittings
Between your tank, valve, and hose sits a handful of small parts that do all the connecting and sealing, and any one of them can be the source of a leak or a mismatch. This category covers the elbows, wyes, and adapters that tie the system together: clear 45- and 90-degree elbows, flanged wye and ell valve fittings, flush fittings, fill kits, and the odd drain plug.

Connecting tanks, valves, and hoses
Fittings are where an RV waste system either seals up clean or drips at every joint. Most are ABS and go together with a bayonet twist-lock, a slip joint, or ABS cement, and the trick is matching the connection type and diameter on both sides. A clear fitting at the dump end is worth having — it's the only way to see when the water finally runs clear.
- Elbows and adapters. A clear 45-degree elbow like the Valterra Clearview or a 90-degree unit like the Camco Rhino Sewer Adapter PRO connects your hose to the ground inlet and threads into a 3-to-4-inch NPT cleanout. The drain-lock ring seals it into the inlet so it doesn't blow back out.
- Wyes and ell fittings. A flanged wye or 2-way ell like the Valterra units combines or splits outlets — handy when you're plumbing two tanks to one hose or adding a second connection point. Rotating flanges let you aim the outlet where you need it.
- Flush and fill fittings. A tank flush fitting (the Icon 2" slip) adds a rinse port to a holding tank, and a fill kit like the Valterra RK907 barbed elbow ties a fresh or gray line into the tank with cement.
- Connection type and size. Bayonet, slip, spigot, hub, and NPT thread don't mix — check what's on your valve and hose before ordering, and confirm the diameter (2" vs. 3") matches.
When you replace a fitting, it's the moment to check the gate valve flange it bolts to and the sewer hose end it mates with — a new adapter against a worn seal still leaks. If you're plumbing a new holding tank, buy the fittings fresh rather than reusing brittle ones.
