The fittings received where actually AN910-4D fittings. What I ordered should have been 1/4 pipe thread.

The fitting received where to large to be AN910-4D which is suppose to be 1/2 pipe. The parts supplied where 3/4 pipe thread.

This with the 816-4D nipple and a SS fuel line from AFP allows me to test individual fuel injectors after cleaning.

AN Fitting AN910-1D Coupling

👍

As expected 👍

The web site indicates that a -2D has 1/4 inch NPT threads. My invoice says I got a -2D, the package says -2D, but the coupler did not have 1/4 threads, more like 1/2 inch threads.

The AN910 couplings that I received had VERY tight threads. It is as if the aluminum were machined to the specs, then the anodizing was done, shrinking the opening dimensions. The other NPT parts could only be threaded in about 1 turn before becoming tight. They should thread at least 4-5 turns before becoming tight. These particular parts might be unusable, unlike Aircraft Spruces usual high standards.
