This is a thicker foam gasket that is made specifically to fit the Dometic RTX air conditioner. The foam is 1" thick which allows for notches to be cut to fit the roof of any van.
We recommend this to go with the Dometic RTX. It is in one piece so it is easy to place instead of having to wrap the gasket around. As well, it is made of a much thicker foam than the gasket included so it will provide a better seal ensuring that there will be no leakage problems.
