Power steering lines Hi or Lo pressure

[RFB]

I split a PS line on the trail the other day, If one looks at the diagram it would appear its the 220. dollar hi pressure line, and yet it has squeeze and remove clamps at either end. so how come I cant just replace it with same length and rated hose. In the diagram it is indeed number 6, its the shorter section of tubig that the diagram is pointing at but it wasnt even a press fitting otr the like. Im replacing all of them now. but do tell. Please

you could have a new line made at napa, probably going to be cheaper than the factory.

if your seeing regular clamps on the lines then I would think that its a low pressure line. the high pressure lines are almost always a crimp fit where the metal line meet the rubber line

Thats what my plumbing exp. tells me they arent even hose clamps they are the squeeze to release guys, I ordered new hoses from wits end, and then ordered a new yota hi pressure line to be safe.

I went with the gates line when I replaced mine:

Gates 365550 Pressure Hose Amazon.com: Gates 365550 Pressure Hose: Automotive

I believe gates makes a high pressure hose also. For the low pressure hose, I used gates 3/8" tranny cooler hose fir $3.50/foot at my local parts store.

I got the gates for now, I just put out for terrain tamer birfs, rotors pads lights etc etc etc So OEM when Im not in a bind.

I have the same one in my truck. No issues so far, looks to be a great OEM alternative.

Yeah the high-pressure line does not have clamps. It's a crimp fitting that looks like this:

Its crazy then Im thinking someone at some point replaced a section, because its identical and yet it has clamps and it did split I dentical ends etc.

Joey @witsend filled me in but I just wanted to try to figure it out, Im going with someone at some point replaced a section and it failed, but she still got me home leaking bad all the way, fortunalty the highway is straight lol

Any industrial hydraulics store will be able to make up high pressure hoses, and they all have crimp fittings. Clamped fittings will not hold more than atmospheric pressure, and are always return (low pressure) lines. High pressure in the hydraulic industry is between atmospheric and 600-psi. Anything above that isn't mobile hydraulics.

One thing to remember, if you do use aftermarket sources, make sure you specify mobile hydraulic hoses and fittings; industrial type (used in manufacturing) are not rated for outdoor use and will fail.

Gates does make mobile hydraulic hoses and fittings, as do Parker, Eaton, Kurt and Bosch. As long as the fittings are certified SAE, JIC or ISO, they are equivalent. (Almost everyone makes their fittings and hoses ion China today) John Deere, Caterpillar, Volvo, JCB and Komatsu, to name a few, all allow aftermarket hydraulic components as replacements on their equipment (though they'd rather see you the same stuff with their labels on them). This equipment sees much more rigorous service than our trucks.

excellent I ordered a gates hose for now as I have spent a boatload not anticipating a steering line failure, But again the line that spilt is indeed on the hi pressure side and yet was still held in place by clips not even hoses and boy did it split, so It makes me wonder did PO splice a piece in or.......

must have been a Russian roulette fan...

The thing that gets me is I just installed a 53mm TOugh dog Stabilzer/RTC and then while wheeling the hose splits. LOL Ill take pics when I get the entire hose out

That’s from a parts website.
