when should brand new old seals be considered unusable
Had purchased a seal kit from someone (not on here) and no names these seals are original Porsche brand new (opened bags) they are quite a few years old and was wondering how old a seal would have to be to be considered unusable. I'm thinking red flag DO NOT USE I would think that over time the seals would lose their pliability and dry out slightly making them prone to leak. Or am I crazy and a new seal is a new seal regardless of age

Not knowing the age, I would skip using them. For all yo know the seal may have been in Arizona dry heat getting dry. Not sure what seal it is, but you may end up doing the job twice. Personally I would not risk it.

Food for thought & why our vendors matter. You could stroll into your local dealership and buy the same seal today that has been sitting on their shelf since 1990.

Easter Seals. At 27 they are pretty long in the tooth. If there are any teeth left.

Almost every driveline-related seal has a pretty significant effort included with installation. The seals you have are -probably- usable, but why gamble?
On the flip side, most oil seals in service see a much harsher life than the same-aged seal sitting on the shelf in your storage area.

Considering how much fun it is to disassemble for a refit, "new" is my recommendation.
