Not exactly...NPTF threads are designed to work without sealers. The "F" stands for fuel and is designated a dryseal thread due to the root and crest of the thread being taller than standard NPT which is designed to be used with some type of sealant.
I did not know that. Thanks for the info.
So the OP needs to find a NPSF male adapter. Or will a NPTF adapter work?
