About 5 months ago, I mocked up my remote
oil filter setup. I have (had

) a billet remote
oil filter adapter block and was using aluminum 1/2" NPT to -12 AN adapters. I screwed the NPT-AN adapters into the block HAND tight (ok maybe fist tight) but definitely no wrench used. I didn't use antiseize figuring hand tight is just that. You know where this is going. Today, I went to final assemble the system, lo and behold one of the adapters was totally seized into my nice billet block. I had to use major force to get it out, naturally ruining both adapter and billet block.
Would it be better to use a steel NPT-AN adapter? Any ideas?
