Frequently asked questions

Can I use braided CPE hose for power steering?
Yes, CPE rubber-lined braided hose with standard AN hose ends is fine for power steering pressure and return lines.

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.

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 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".
