It's listed as "new other" – basically brand new but might have some storage wear as the seller notes.
But the seal itself is in good shape, so it'll work fine.

If your old gasket is cracked, flattened, or leaking, this replacement will get things sealed up tight.
No warranty info, but it's just a rubber gasket – not much to go wrong.
It's a specific part, so double-check your Danfoss model and tube size before ordering.
But if you're working on a KPS 79, this is the right fit.
