Hot Water Cylinder heating element tube spanner. I have a hub nut wrench I got from 4wds years ago but it is a bit loose, I think it is 53mm & the real deal should be 52mm or somesuch. I had read on here that these heating elemnt tube wrenchs are the go but when the local Bunnings had them for about $23 from memory I decide to make do with what I had. not like I was using it every day like. I just like buying new tools.:cool: I think it was in the plumbing section, maybe electrickery. More discussion about these tube sockets here http://www.aulro.com/afvb/technical-...ut-tool-2.html
