How about silicone tubing or something like this: http://m.summitracing.com/parts/vpe...mR0HXiSjq_3-8BhL8M022lugo4Hy4seHPHBoCvvDw_wcBI've been thinking about this, and I'm wondering if cutting a 1.5"-2" length of bicycle inner tube, and stretching it over the female cord connector and then rolling it back until plugged in, then rolling it forward over the male connector on the heater element would work?
Just leave it rolled back on the female connector when not plugged in?
I have 2 I'm waiting to install. I have silicone sheet, I may rig something up with that. Probably cover the inside and caulk around the base as well.
