The o-ring closest to the mouth is too tight
Make sure that you are using the correct sized condenser Xrings. The condenser Xrings come in two sizes; a larger and a smaller size. Take The Xrings off of your condenser and compare them, have a good look.
The Xring located at the end of the mp where you place your lips should be the smaller Xring. The next Xring that sits inside the stem but nestled up against the other end on the mp should be the larger Xring.
Here is a link to the Dynavap FAQs. Scroll down to the compatibility chart to see the correct Xring placement.
