I've been researching all morning on the difference between AN and NPT. I have found sizing charts and so forth but nothing tell me what would be a solid way to determining if your fitting is AN or NPT. I'm trying to find an oil restrictor for my Turbo but I cant determine if its AN or NPT and I have to order this over line as no parts store has this item available... Can someone tutor me on the difference between AN and NPT? How to determine if it is AN or NPT?
