Hydraulic Hose

[CarbonSteel]

Gang,

What hose would you recommend for handling engine oil? My top pressure is 85PSI and the operating temperature is about 240F. It will have crimped -10AN (JIC) fittings and I believe that a 1/2" ID hose is more than enough to handle the volume. Last, but not least, it needs to be flexible.

Input welcome.

A little more information on the application would help. I'd personally get a braided steel hose from someone like Speedway motors, Jegs or some other racing outfit that does this. You can also visit a local Parker hose shop and they can make you a hose.

Curious why you think a 1/2" hose will work when you are using 5/8" fittings (-10AN)?

Just my $0.02

I think that braided stainless would be too stiff. What I meant was that 1/2" would be enough for the flow capacity requirements, but yes, the -10AN fittings are 5/8". I plan to have a hose made but was curious as to what everyone is using.

The application is a 2019 3.6L Wrangler that has an oil pressure maximum of 80PSI (typically 33PSI at less than 3K RPM and up to 80PSI above 3K). The oil temperature is typically 230F. I am looking for a hose that can handle the temperature and be flexible as it will need to have a 4" bend in it. The pressure is not really an issue since most hydraulic hose can handle exponentially more pressure than what I have.

I've done this a couple of times. The shop will know which hose is appropriate, or you can look on their website. They have good descriptions for each series of hose and which fittings can be used.

fair enough. I'd call your local Napa store or Parker hose store. They will probably be the experts for you.

Issues using push lock hoses for oil cooler

I wanted to replace the oil cooler lines on my 1981 MB 240D. Was already doing other maintenance, one connection was seeping a bit, and the rubber was original... These lines are notoriously difficult to maneuver in and out, even with the engine lifted and an engine mount out. Many owners find...

That looks to be perfect--just need to be sure it can be used with crimp on fittings.

Thanks!

Per my thread 836 is press on. You can’t change fittings or get an adapter?

I am curious if there’s a version of 836 that crimps on or uses other barbed fittings…. I have need for some custom hoses myself.

Edit: I just looked…

I don't want to worry about the fittings pulling out. The hose will see 80PSI and a lot of vibration over time.

See edit above. They can be crimped. I’d suspect that Parker as a reputable manufacturer figured that issue in their design and test.

Nice, just need to get the cooler mounted, get some measurements and go shopping.

Thanks for the info!
