Are you using pipe dope as a lubricant or sealant? I always thought the dope would be used for craft stored in water over winter. I ask only because my new boat uses a brass plug and previous boats used the rubber type plugs. I've got little knowledge of using the brass plugs. thanks, Sean
The pipe dope is the sealant. You don't need a lubricant with brass like you do with plastic. It stays flexible, so it's not a mess to deal with. Are you trailering or in the water?
Some info for you on this:Leakage path through NPT threads shown at red points. No matter
how tight you make NPT threads, a leakage path still exists. It is the function
of the sealant to block the path between the male and female thread.
You can go by NPT specifications, but that's probably over doing it as they are for installations to be static. Those call for about 2 turns after snug. If you have it 'tight' with a wrench, you are probably OK. Remember these are tapered threads, and if you do not draw them together well enough, it will rapidly loosen. Beware if you do decide to use teflon tape, the friction is greatly reduced and can allow you to over torque and damage threads.
