I'll check the girls tonight, I think most of them have the older style m16 connectors with just the thread running along all of it. That may also work instead. Best of luck with the plumbers tape solution, The Doll House are very expereinced with these matters :)
@kaede_waifu Thank you.
@kaede_waifu Thanks! I've not tried it yet, but I'll post when I get time to try the Teflon tape.
