AN Fittings for Oil Cooler...Where???

[Hal Copple]

I have done a lot with AN stuff on my car, was out in the garage last nite until late working with Teflon AN 4 hose and ends for my trunk mounted Halon system.

I kinda like making up fittings, they are just such a work of art when they all come together.

There is some learning curve with AN stuff, and two basic types of ends, nipple and cutter types and single cutter. The best is a bit more, but perhaps more reliable, as if we need 3000 psi!

I do suggest you use hose and ends from the same company, to make installation of the ends easier. Be sure your tetanus shot is up to date, as you will loose a few drops of blood doing AN hoses.

Personally, i have been happy with Earl's nipple and cutter, i get my stuff usually from Summit, or my local speed shop.

You don't use teflon tape or sealants on AN connctions, although the NPT stuff should generally use these thread seals..

If you are going to be doing much AN work, get a set of wrenches specific for them, nice and short, so you can work in crowded places.

Keep some bandaids on your workbench!!
