I'd replace it. I thought mine were good too, along with my shrouds
and stays that looked good. Then one day after reading an article
about shrouds breaking, I looked at each of the 20 yr old old fittings
with a magnifier and was amazed to see tiny, tiny cracks. Each crack
was revealed by a tiny brown streak where the steel in the crack had
become non-stainless, amazing. I replaced all of it.
