Frequently asked questions

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 do I tell what size my AN fitting is?
Measure the outside of the male thread and match it to the size chart above. For example, 9/16" (about 14.3 mm) across the thread is AN6, and 3/4" (19 mm) is AN8.
