What size is the AN fitting?

This adapter uses a -4AN fitting. AN fittings are sized in 1/16" increments, so -4AN is 4/16" or 1/4".

What thread type is the 1/8" side?

The 1/8" side is female pipe thread (FPT), also known as National Pipe Thread (NPT). This tapered thread seals as it's tightened.

This adapter is commonly used to connect gauges or sensors to AN fuel or oil lines. It provides a secure and leak-free connection.
