Great gasket
Magneticboogers (WI) | October 6th, 2024
The one I pulled out was just a square taper, this one almost snapped into place (not quite but hard to describe otherwise) and it fit great and seals great. Really impressed with the tolerance of it.

Everything fit alright but the packaging was awful and was just balled up in a bag.
