BX2350 hydraulic line leaking

[Zick]

This line just starting leaking right at the nut. Is this a case of needing to tighten more or replace the line?
I tried to loosen and re-tighten but it seemed like it made it worse.

Is there an o ring or some other kind of seal in there.

Not sure yet, I was trying to look up the parts diagram on messicks site but their site isn't working for me.
I haven't pulled the line off yet as I was hoping it might just need to be tightened more but I tightened it pretty good (I thought).

Did some research on this, and that line goes to a 9/16 connector that has a rubber o-ring. However, it looks like you leak is on the flanged side.

I would first get two box wrenches and tighten the heck out of it.

Thanks, now I'm wondering if it might be leaking at the o ring side? Quick look seemed like it was leaking more from the nut.
Going to pull the tire tomorrow and get a better look.

On my BX2200, there is a 45 degree fitting that I recall got loose at least three times in the past 20 years from vibration. When I notice it wet, I just get two box wrenches and tighten it up and it is good for a very long time. Hasn't leaked in at least 5-6 years.

It is amazing how small amount of a turn it takes to seal it up. But 2000 PSI of pressure will do that.

Otherwise my machine has been leak free other than a few consumable hoses.

I do plan on replacing all the hoses one day before one of them fails and goes pop making a gigantic mess.

At least on the BX, the lines don't run higher pressures like some of the equipment I use at work. Upwards of 4000+ PSI. Things get interesting on high flow, high pressure systems.

Being safety minded as I do, never put your hands near that when the machine is running due to skin injection hazard. ~2000 psi can still do this. Use paper or cardboard if you absolutely need to see if it is leaking while the machine is running.

Good luck.
