I found a picture of one in the Alemite catalog, but can't download the picture.
And don't get me wrong, some manufacturers call them needle adapters, but they are big enough on the end to seat in the socket of the flush fitting.
Just don't get one so small it would push in the ball by itself. I have seen lots of people at work ruin flush fittings this way.

A needle isn't quite what you want to lube a flush fitting. A needle fitting is more for injecting grease under a rubber seal.
A needle will contact only the check ball in the fitting, and not seal around the fitting. Plus, it can damage the ball and spring.
You need an adapter on the gun which seats in the socket around the check ball in the fitting. Then the only thing that opens the ball is the grease pressure. The proper adapter will be tapered and rounded on the end. The end will be about the size of the socket on the flush fitting.

"A special needle nose grease gun adaptor is needed to grease the flush type fitting..."
It's still a needle, just make sure it is "nose" (blunt) instead of "injector" (sharp). A good reference is the Alemite B201 or B202 Narrow Needle Nose Adapter (not sure if one works better than the other - maybe someone can chime in). The auto parts stores I checked carry both so it probably is easy to get mixed up.
