T1022BK by Valterra is a black 10-inch sewer hose extension adapter designed for recreational vehicles. It extends the waste outlet connection from beneath the RV, making it easier to connect a sewer hose during tank drainage. The adapter features 3-inch bayonet hooks on one end and 3-inch bayonet lugs on the other, allowing it to twist into place without requiring hose clamps. A built-in seal helps provide a secure connection. Confirm the fitting style and diameter of your existing sewer outlet before installation.
