I see that West Marine sells Teflon Flax and GTU Gore. But in googling GTU, I came across GFO Gore-Tex dripless packing (see www.gfopacking.com)
. Does anyone have experience with GFO?
Gore GTU and GFO are the same thing, to the best of my knowledge. I used whichever one WM sells. Works great. It's not entirely drip-less, however, just very low drip rate, once it's settled-in.
Sorry: Can't help you with the size.
