quality oils do indeed have seal conditioners, but they're not the same
as seal swellers, the garbage you buy in a little bottle that offers
temporary respite before things fall apart for good. [conditioners are
mainly plasticizers that keep the material flexible enough to do its
job. there may be a little swelling, but it's small. swellers can
bloat seals almost unrecognizably. they offer sealing while the seal is
still in swell mode, but after that, it's completely gone.]
