Small leak in flexible coupling on boiler

I have a Dunkirk 095-200m boiler.  There is currently a small leak coming from the flexible coupling between the boiler itself and the 2 inch pvc vent pipe.  Is this as simple as getting a replacement coupling?  See attached picture of the leaking coupling and a stock picture of the replacement.  Any advice would be greatly appreciated!

    That is a transition coupling from the Aluminum block and the pvc. Hopefully thats the issue and not the aluminum...
    You will need to get the specific part from ECR/ Dunkirk as that one is rated for high temps and a simple Fernco is not.
