Frequently Asked Questions

What does the AN size mean?

AN (or dash) sizes describe the hose size in sixteenths of an inch, so -6 AN is 6/16" (3/8") and -8 AN is 8/16" (1/2").

Do AN fittings need thread sealant?

AN fittings seal on a 37° flare, so the flare should not be sealed. Tapered NPT threads do need a suitable thread sealant.

Will this fit my hose and fittings?

Check the thread size, AN size and material in the specification before ordering. Contact us if you need help matching parts.
