Lack of confidence in wicking solder completely into a joint. And you don't have to sand /de-oxidize when things are threaded. Disassembly ease is a legitimate reason for use of non-soldered joints, so it is not all attributable to my initial remark. I like to weld and silver solder(really silver braze) and use pipe /plumbers' solder. Some do not enjoy those processes so threaded with good Loctite thread sealant is quite sufficient.mike( I use teflon tape too, but the Loctite inspires more confidence for me.)Sorry- it is necessary to acknowledge that black iron threaded -joint pipe with sealant is the prevailing gas distribution material/system in the American home and it is safe and works well.-Without this amendment, my post seems pretty disrespectful or critical in a mean spirited way- that is not me)SORRY
