Exploded a braided line PS hose and want to replace it with the best hose out there. What should I use?

I am running hydroboost. Is it true the only high pressure line is going to be between the pump and the box?

Thanks,
Kirk

High pressure from the pump to the hydroboost, and the hydroboost to the PS box. Depending on the pump, pressures could exceed 1500 PSI. Use hose rated for 3000 PSI.

Aeroquip Teflon hose is rated at 2500 psi max operating pressure. Should be plenty of cushion for power steering pressures.

Local hydraulic line place just built mine rated for 5000 psi. $45 ea... so $90 for both lines.

Up here in San Jose there is Royal Brass, a company that builds and supplies all kinds of fittings and hoses. They built me a set for my ps install for under $100.00. You might look for similar companies in your area.

Exactly. That's all I've ever used and abused. Burst would be in excess of 3500 psi.

This is what burst on me. Russell brand. Teflon 2500 PSI (not powerflex). I'm looking for a more durable hose.

This is the route I am thinking about going. Wondering if I can find them online. Just need two 2' hoses with 6-AN fittings and 90 degree bends on each end. Maybe a third for a spare.

I posted what I consider to be the best field serviceable/repairable in the PS Fluid thread.

.....
In industrial hose a qwik glance at the Weatherhead catalog ( http://www.eaton.com/ecm/groups/public/@pub/@eaton/@hyd/documents/content/pct_1580804.pdf pg.10) says FC300, FC310, & FC510 hoses are used for truck hyd. PS systems. FC310 has a maximum working pressure of 4000 psi and a minimum burst pressure rating of 16000 psi for the -6 size (pg 41) and uses various reusable fittings starting on pg 151, so field repair and build it yourself hoses are still an option. This would be my choice for it's field serviceability and it's smooth rubber OD. It looks a bit like FC332 hose on the outside, only bigger, and so it won't hold grit in the braids and abrade itself to death.

I built mine using reusable hydraulic fittings and hose from an industrial supply store. If I blow a line I can simply replace the hose using regular hand tools on the trail and keep going. The fittings are about the same price as regular AN fittings and you buy your hose by the foot. Just keep an extra length of hose that's the same as your longest hose and you'll be fine. My hoses are 8 years old and still look brand new...

Sounds like you made a braided power steering hose from racer parts. Probably fuel hose only rated for a few hundred PSI.

How blingy does it have to be for you? Hydraulic shop can build stuff that is usually a bit stiff with bulky ends on it. I've had great success with the blue hose that Speedway Motors sells for power steering hose. It's braided stainless inside but blue cloth outside.

The fittings have to match the hose. AN ends do not interchange among different brands or lines of hoses. The wrong end will probably end up blowing off the hose.

Never, ever use anything to seal the threads of an AN or JIC (they're the same, just aluminum vs. steel) fitting! The seal occurs in the mating tapers. If an AN/JIC fitting is leaking there are dead-soft copper or aluminum 'gaskets' made, but if/when possible the fitting with the problem should be replaced.

I've always used engine oil for hose end assembly. Hose end to adapter threads I just make sure they're clean unless it's an oil system hose and then I don't worry too much about the oil in the threads UNLESS we've lost an engine - then everything got thoroughly cleaned if not just replaced.

For a PS system I'd use PS fluid for the hose to hose end assembly.

Decided I wanted to make my own and went with the areoquip brand (rated to 2500) going to build an extra hose to keep in the spare box.

Hey,

I installed a hydroboost about 4 years ago using Russell stainless steel braided hose and steel fittings. I now have a weeping leak at one fitting. I haven't pulled it apart; but, I'm thinking about just replacing the hoses while I'm at it based upon the recommendations here (Aeroquip).

Just a couple questions so that I make everything right the first time:

1. The Aeroquip hose is shown to be 0.001" larger in OD. I'm leaning towards replacing the Russell fittings with Aeroquip thinking it might be a leaking fitting at the box. Before spending $80 to replace the fittings, I thought I'd just throw this out there... Good idea to use the Aeroquip fittings with the Aeroquip hose?

2. The steel fitting that I'm looking at from Summit is this:

http://www.summitracing.com/parts/aer-fbm1122/overview/

It's -6 AN x -6 AN; but, there is reference to it being compatible with 37 degree AN adapters. I'm thinking that's not really important being that the fittings that I'll be mating to are - 6 AN. Just want to make sure I'm not overlooking anything.

Thanks for any feedback.

Take Care,

Jeff

Look for the local Parker Hydraulic store. Royal Brass mentioned above is one in the San Jose area.
