Diaphragm intallation into wastegate problem

Dear all,
I replaced a torn diaphragm on a 1977 Turbo recently.

Unfortunately I have problems getting the diaphragm sealing off properly. When testing the unit with air pressure of about 1 bar I can hera and feel that some air bypasses the diaphragm. The diaphragm ist fine, but it is not sealing properly with the body of the wastegate.
Is there any trick or method to improve this?

Thank you for any tips on this.

Kind regards,
