Frequently asked questions

Are AN and NPT the same?
No. AN is a straight thread that seals on a 37 degree flare. NPT is a tapered pipe thread that seals on the thread itself with sealant. You need an adapter to go from one to the other.

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.

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".
