Claim 21:
22. The port sub as claimed in claim 21, wherein:
the standard flow port sealing configuration includes a leachable metal, the degradation-promoting agent includes a lixiviant, and the co-operation between the standard flow port sealing configuration and the degradation-promoting agent is such that the emplacement of the degradation-promoting agent in the respective degradation-effective communication with the standard flow port sealing configuration is with effect that the leachable metal, of the standard flow port sealing configuration, becomes leached by the lixiviant, of the degradation-promoting agent, such that the degradation of the standard flow port sealing configuration, by the co-operation between: (i) the degradation-effective communication with the first end sealing surface of the standard flow port sealing configuration, and (ii) the degradation-effective communication with the second end sealing surface of the standard flow port sealing configuration, includes leaching of the leachable metal of the standard flow port sealing configuration.
