Al, SK has XRP brand, some seem to swear by it. I ended up using a bunch of their stuff just because that's what SK carries. It's not bad but I prefer the Russell brand, I have had good luck with it. Since I don't live near SK anymore, I looked at some fittings on Summit the other day and Aeroquip seems to be slightly cheaper than some other brands.

Moreland Belt and Hose in Freeport carries Aeroquip stuff.
