Order one from your nearest Airstream dealer. The fittings are different than you will find at other RV retailers.

If I understand your post this what you might need.

Amazon.com: Valterra T05-2285VP Thetford to Valterra Universal Adapter: Automotive

If your trailer has the original sewer connector, it's a Thetford connector that uses a Thetford-style (and size) cap. Most of what you find these days is Valterra, which is a slightly different size and has different tabs for the connection.

The Thetford parts are available, they're just not the most common now. This link just happens to be the first useful one that came up in a search, many other stores and websites stock what you need.
