Phantom diving parts

[CenTexDivin]

I've been trying to think of some peices of diving gear that may or may not (hopefully not) exist. Things like aluminum tank liners or something along those lines. When I worked on cars, we used to joke about phantom parts like blinker fluid, muffler bearings, wiper blade sharpeners, and 710 caps (OIL upside down). Just wasn't sure if anyone else had heard of some rare "parts" like this.
