[AT] Hydraulic fitting

[Dennis Johnson]

Spencer,

This looks like it is a NPT Female hose swivel that is screwed into a nipple which is screwed into to coupling welded to the cylinder. The swivel fitting has a cone that seats on the ID of the nipple. This was a more common setup on older cylinders. My guess is that the threads have rusted together.
One way to get it off is cutting or grinding the hex swivel to relieve pressure. The other way is brute force. You can replace this swivel adapter with a new one.

Thanks
Dennis

I am having a heckuva time getting the hydraulic fittings off the cylinder for my haybine. Is there any possibility they are reverse thread? I've never seen that before but I've tried heat and penetrating fluid for more than a day and they're not budging.

As you can tell from the hose, you can see why I'm replacing the it :-)
