two seals

Hello there!

Thank you for reaching out to us. The 58-053 and 58-114 come to mind for the bubble seal. Neither of these seals have a 1/2" bulb diameter though so you may want to double-check to be safe. Review the specifications below and see how they compare with yours.

Unfortunately, we believe the leaf seal is discontinued and no longer available. I'm afraid we don't have an alternative. I am very sorry for the inconvenience.
