Pipe thread sealant.....thru hull and bait well pump

[Duffman]

Installing new bait well pump. Male plastic fitting on pump to bronze female on thru hull. What to seal threads with?

My head is spinning with what I have read......

Use 5200.....don’t use 5200
Use 4200....don’t use 4200
Use Teflon tape
Use pipe dope
Use Teflon tape with a coating of pipe dope
Etc etc

Pump manual (shurflo) simply states “seal with thread sealer”

Was at Edison boat show last week looking in bilges and every connection was sealed with some kind of liquid dope. Salesman had no clue what was used in fit up.

If I didn’t read so much into it I didn’t even realize some sealers will actually eat away at the plastic.

Just looking for some suggestions as I over think the hell out of this!
