Last year I got my steering cylinder rebuilt as it was leaking. Seals were changed, rod was polished clean and everything was fine.
After a winter on the ground I noticed again some leakage. This time it is not the cylinder itself but the fitting connection. The leak is very tiny, but after 6 month on the ground it was clearly noticeable.
My setup is as follow:
From the helm the line is copper.
Between the cylinder and the copper line there is around 1 foot of hose, quite stiff but less than the copper line.
Fitting on this hose, both side is compression fitting with olive/ferule. And this is where the leak is.
I am not sure if the fitting on the cylinder is NPSM or compression.
To illustrate what I mean here is NPSM fitting:
So the questions...
First: Is compression fitting common for hydraulic? Is it the right thing?
Second: Any advice on getting this leak free?
Last: any recommendation on hose to be used? I found a lot of different hoses that could fit.
