Hydraulic fitting question for the experts.

Ultradog MN · Jun 27, 2020

This fitting is off the hydrostatic
steering on my 66 Ford 4000.
I'd like to replace some of the rubber
hoses as I go as they are original to the
tractor.
The hydraulic house I usually deal with
can not get these fittings.
Does anybody know what this type of
fitting is called and if there is a
replacement?
FYI, they do not use an Oring or washer
of any kind. They are metal to metal
connections.
Thanks

I take it they're not leaking yet.

If you remove the crimp portion of the fitting without damaging the tubing you can: 1. Braze a male or female fitting to the tubing. 2. If the tubing is the right OD, install a Swagelock style flare fitting. 3. If the tubing is the right OD, install a compression fitting.

At least with 2 and 3, you can figure out if they're possible before you cut into the fitting. Brazing/silver soldering is more forgiving.

Thank you Check Break.
There are 6 of these type fittings that
go into a manifold in the bolster.
The two of them on top required a 90
degree bend to get them in there.
Those I bought the fittings and brazed
them to my old ones.
Easy enough but Expensive for the parts.
The other 4 are in a Very tight location
and I'd like to change the routing of the
hoses to make it easier for future access
- have to remove the bolster to get in
there. The nuts on a couple of them are
pretty hacked up too.
The right fittings would sure help.
It might be easier to make a new manifold
for under there and I'm considering that
as an option.

hello if I recall right there was a small oring on the small end went inside but I also think you can use male oring fitting the threads are the same

There is a oring on middle step. Thinkin its -011.

Sounds like you have a row crop tractor sub model 4200 to have hydrostatic steering

Nice job. That's about as tight as you're going to make a 90* bend. Any chance you could build steel lines to get you through the bolster so as to free up some real estate the hoses take up, or are you trying to maintain the OEM look.

I've made a few steel lines this past year and had good luck with them.
