Just any tube of "thread sealant"? any certain temperature rating or purpose exactly?
You need adapter fittings - the Wilwood RPV's are NPT, not AN. While you can probably get the AN's started, they will never seal permanently and sealant is not the best way. It's a last resort on like fittings.

Lots of bits and pieces shown here - and an easy site to navigate. A few bucks more on the right brake line fittings can save lives - and not a place I would scrimp.
