Yes it does create a seal, but it creates a seal because it becomes pressurized because of the taper. As you thread the NPT fitting in, its diameter is slightly increasing so it starts slowly adding pressure, that's why you can never 'fully' tighten NPT fittings. And I am using crush washers. The M10x1.0 to 4AN fittings came with a crush washer to seal for liquid/air and the 2 additional washers I used on the bottom fitting are from the banjo bolt fittings that came with the wastegate. When I get home from class tonight I am going to install it and we will know for sure if it works! I hope it does because I really don't want to take it out again, and I really don't want to use rubber lines with the banjo fittings.
