I've never seen one flat on both sides, but I'd still recommend
installing it with the nylon part AWAY from the union.
The reason is simple. If you look at the stresses on a bolt/nut joint,
nearly all the holding power is in the first thread or two at the union.
Nylon doesn't have nearly the holding strength that steel does.
