[AT] hydraulic pipe question

[Grant Brians]

Black pipe and stainless steel are the recommended types for hydraulic oil.
The reason is that there is some concern about flaking of galvanizing off of
the pipe and then contamination/plugging of valves in the hydraulics.
Obviously a good filter should eliminate those concerns, but that is the
rationale. In the case of black pipe, the only concern is rust and inside of
the pipe filled with hydraulic oil, clearly there is no real worry there.
The only secondary concern would be pressure as mentioned, so just make sure
the pipe is in good condition and is rated for the hydraulic pressure you
plan on using. As a reference, I have 1/2", 3/4" and 1" black pipe lines on
our earthmover (Be-Ge low pressure system) and several 3500psi tractor
systems.... Go for use of black pipe....

Quick question on pipe suitable for a hydraulic line on a Ford 8N.

I need a short length of pipe to run from the hydraulic test port up to
the front of the tractor.  The fitting I have to connect to the test
port accepts 1/4 inch pipe, which I will need to size up to 1/2 inch for
the coupling.

What type pipe would you all recommend, or would I be better off running
the whole thing in hydraulic hose, and rigging a heat shield where it
runs next to the muffler?

The line will be used to run the hydraulic cylinder for a Sauder snow plow.

Thanks,
Howard
