Don't think so because it acts like a bolt. Never notice gasket, mine were probably apart before.I'm wondering if that's a pipe thread? Never checked.
Nothing shown in the parts manual.. just a Tee and the Vent bolt. The Tee isn't sealing anything so I doubt they spent money on a gasket..Is there for sure a gasket that goes between the TEE and the axle?
Thanks guys. I don’t recall feeling a vent type bolt. When I get back under her I will see what it is but at least I know what it should be if its not.
