O-ring / seals replacement
This question is regarding all seals in general (0-rings, gaskets, etc.)
Unless the maintenance / service manual says to replace the seal if it is damaged, otherwise it can be reused, is it ok to not replace the seal if it was just replaced a few hours or days earlier?
Example - I replaced a hydraulic filter and it's seals with new ones as part of a routine maintenance check. Few days later due to some other defect arising related to hydraulic system, I am to remove and inspect the filter. Upon removing and inspecting the filter everything is ok. Should I reuse the same seals as I was the one who replaced it only a few days earlier and the aircraft is still undergoing the same maintenance check?
Of course the manual says to replace the seals all the time, but this is already done by myself a few days ago... And by some luck new seals are no longer in stock...
