I have a pair of master cylinders just like the one in this picture. The female thread in the the housing that receives the AN hydraulic fitting is not a pipe thread. It looks like that blue fitting is an adapter with an o-ring boss on the far side and a female pipe thread on the near side. Am I correct? But I don't see a fitting like that in the Aircraft Spruce catalog. What AN fittings are we really looking at here?
