Hey guys, could anyone tell me the correct way to install male threaded fittings into a water tank? Would I use thread tape, o-rings or anything else for that matter? I tried asking the guys at westmarine but no one had an answer for me. Thanks!

I have had good success with tape on plastic fittings. Not sure I would use anything permanent, odds are, you will need to repair/ replace in the future

Simple...Teflon tape and pipe dope. Just put the pipe dope on the edges of the insert thread after Teflon tape. Minimal amount needed. No rocket science needed here.
Monster tape is awesome, but any tape would work.
Run tape on the fitting to the right {clockwise} so as it is screwed in then the tape won't back off.
Thats all you need. Don't over wrench.
Make sure you have visual access or hatch for future work. Don't bury it.
