Putting seals on means gluing them on, so it would be wasted effort to fit bad seals.
Either duck tape the wrists and the neck then see if you can do a pressure test.
Or
Take a gamble and have new seals fitted
Or
Fit the seals your self, you can always have new seals fitted professionally later if you are unhappy with your craftsmanship, once you have tested the suit.

The person in question is talking about a DUI drysuit that has ZipSeal attachments. There is no gluing on required.
To the OP, It's likely the suit is fine. Awesome deal! Do you know anyone that already dives a DUI drysuit? Perhaps they can temporary take seals off their suit for you to test. It only takes a couple minutes to swap out seals.
Typically our rental suits do not have seals installed on them for same reason that @boulderjohn mentioned. We fit different seals for rentals and put them in sealed bags with talc to make them last a little longer. I would take a guess that is the reason the DUI suit you bought did not come with seals.
In any case if you're in Long Beach. DUI's headquarters are in San Diego. 2 hour road trip for you?
