Frequently asked questions

What size is an AN6 fitting? Is 6AN the same as 3/8?
Yes. AN6 (also written -6 or 6AN) suits 3/8" (9.5 mm) hose or tube and uses a 9/16"-18 thread. The dash number is the size in sixteenths of an inch, so AN6 = 6/16 = 3/8".

How do you install AN fittings on braided hose?
Wrap the hose with tape and cut it with a fine blade or cut-off wheel, push the hose into the socket, then screw the nipple in until it bottoms out against the socket. Oil the threads first and use soft jaws or AN spanners so you do not mark the anodising.

Do AN fittings need thread tape or sealant?
No. The seal is made on the 37 degree flare, not the thread, so keep tape and sealant off the AN side. Only the NPT (tapered pipe) end of an adapter needs sealant.

Can you reuse AN fittings?
Yes, AN hose ends are reusable. Check the flare and threads are clean and undamaged. PTFE hose ends need a new olive if you rebuild them.

How tight should AN fittings be?
Snug them up by hand, then about a quarter turn with a proper AN spanner. Aluminium fittings do not need much. Over-tightening can crack the flare.

What size fuel line do I need for my horsepower?
As a rough guide on petrol EFI: AN6 is good to around 500 hp, AN8 to around 800 hp, AN10 beyond that. E85 needs about 30 percent more fuel, so go up a size if you are running it.
