I'm rebuilding the 77 van with hydro (stop laughing, you at the back) as I want it to ride nice. It will have shocks at front and comp hydro bump stops at the rear.
Rather than get special length steel pipes bent up, I'm considering using Pirtek MPH-08 hydraulic hose, run through the 2 floor channels.
This stuff is textile braided, rated to 500psi WP, can anybody see a problem?
I could use plastic pipe, but at 300psi I'd rather trust hydraulic hose...

There is a plastic pipe that will handle the pressure. Parker Parflex is the stuff.
It is similar to what was used on the hydro pumps so it will handle the pressure.

I've never measured, but whats the maximum shock pressure one might expect from hydro suspension? The plastic tube replacements have been used for a few years now however..

Not high enough rating. You need minimum 1000 psi WP to take in to account dynamic pressures. The 300 psi tubing won't last very long at all.

I recon it's a great idea!

I wonder what the rating on the std bag hoses is, they are textile too but 40 years old, I doubt were 1000psi...

The std hose on a displacer isn't single ply. Texile hoses are available up to 5000 psi WP and possibly beyond.

Think about this. The static pressure of the system is around the 300 psi mark. What happens when your race over yr cattle grid at 60 kmh? Not to mention a landing from those weekend rallies that you also like to do remember too that the system is dampened and so will further increase pressure. It wouldn't be too hard to actually calculate the hydraulic pressure.

_________________

The pressure does not increase that much. The rubber spring on the top of the displacer is not a 1000psi spring.

I'm sure Pirtek had a better hose, however their catalog gives me an error 404 when trying to load.
And the Enzed site is damned useless...

[edit] the MPH-08 hose has WP of 35 bar (500psi), and min burst pressure of 140 bar (~2000psi+)
I reckon it would handle it. If not, it'll pee and I'll find something better.

That Morris 1100 in your sig has been copping a hydro suspension hiding for about 6 years Morris. It must be due to blow a bag sometime soon?

Just because you don't understand how hydro works.

I'll second that.
Morry your right again

This stuff would do it, I used to use similar for HP argon line connections. But I bet it ain't cheap, and doesn't like bending tight.

Kevin,
Would do the job for sure but overkill in my opinion.
My choice would be this and is cheap as chips, well up to the job.
