My dealer made up some hydraulic hoses for me. He put ends on the hoses that are threaded, with an outside diameter of 3/4". The inside diamter is about 1/2" (I'm not sure how to correctly refer to this, should I call these fittings 3/4" or 1/2"?)
Anyway, my main question is this: I was told that these were pipe thread fittings. I think that is correct, as I remember hearing that pipe threads are tapered, with the end of the fitting being slightly tapered in. When I look closely at these fittings they do indeed appear to be tapered.
When I turn these male pipe thread fittings into a female pipe thread fitting, they seem to fit very well. The fitting turns several times before "bottoming out".
However, When I turn this same male pipe thread fitting into either flat front hydraulic connector, or a ball/poppel style hydraulic connector, it turns only about 1 1/2 turns before stopping.
Are hydraulic fittings usually pipe thread or some other thread pitch/taper? Something just doesn't seem right here, and I don't want to wrench on it before I'm certain.
Thanks,
Tom
