Hydraulic Hose Assembly Question

Most applications require you to have custom hoses made up. There are various diameters, threads and the length can be very important if it is amongst other hoses or connections. They can be very tough to install if too long or short. It really depends on what you are trying to either replace...or make.
If you are replacing one...order from the OEM place that may have the same hose. Getting them made up is not a big deal...a bit pricey...but even NAPA auto parts where I am makes mine up for my Kubota tractor.

That is a hydraulic hose of a certain length with two 90° female fittings or whatever style the fittings are. The fittings are clocked in relationship to each other to ensure a nice fit.

Those are custom. From the picture the look like JIC fittings but could be FU as well. Every hydraulic shop worth a damn will have the fittings in stock and the saw and swaging machine/dies to do so. Even a lot of shops or equipment dealers will as well. Where I work does as well as the local caterpillar, John Deere, and case dealer if they are JIC or face seal. A kamatsu dealer should have FU.

Usually custom made
When it comes to our hose shop either the customer brings in a hose for the replacement to be built as a copy or if they have the part number for our brand (either off the hose tag or the parts schematic) then we can look up the build instructions and build one without the failed hose in hand. We are equipped to do common fitting sizes/types and have several different diameters and types of hoses
You may also find generic hoses off the shelf from Northern tool. These can be used for some applications but generally it’s best to have a proper hose made.

A lot of O'Reilly Auto Parts stores will make hydraulic hoses. Just another option.

Your local Cat dealer can build you about anything you want.

A good study guide is Parker 4300 tube fittings catalog which you can find online thru Google search. Parker 4400 hydraulic hose end fittings have all of the options for hoses. There is a ton of info there, you can fix a lot of stuff with those two pieces of info.
I personally like the JIC fittings, although that one looks like the clocking of the ends would need to be customized.

That would most likely need to be made up for you due to pressure requirements. Some NAPA stores, just about any hydraulic shop, or any equipment dealer can make you a hose. Order it from the equipment manufacturer. From the picture it looks like two 90° elbows that are indexed 90° from each other. What's the hose for?

A Forklift repair company can make those up for you too or they will send to larger specialty hydraulics company to make for you.

That one is made for a specific machine. It's not that it can't be made up but looks like flare nuts. It's only semi generic, would need adapters to npt.
Dealers used to be greedy about belts hoses, filiters and bearings and guys started finding alternatives. They lost a lot of connection and part biz and many came around to be more competitive. I check now many times when something is more specialized. Sometimes they are modest and not worth the fuggin around when perfect fit is available. .

As previously mentioned, that looks like a hose made for a specific application. Generally speaking, it's a no-no to crimp two 90 degree fittings onto a hydraulic hose unless absolutely necessary. And if so, it's VERY important to test fit the hose and fitting assembly on the machine before crimping, and using some sort of paint pen or marker to put witness marks on the hose and both fittings. This will help insure the fittings are crimped onto the hose in the correct orientation, and prevent any "built-in" torsional twist within the finished hose, after installation. Normally, hydraulic hoses that are supplied in bulk at "farm stores" usually have just straight male pipe threads on either end, then you buy the correct adapter to make the hose fit on whatever you're working on. Some hoses have one 90 degree fitting with a straight on the other end. This is fine because you can get any torsional twist out of the hose at the time of installation by adjusting the "straight" end of the hose. I forget how much exactly, but having ANY built-in torsional twist in a hydraulic hose will GREATLY reduce it's life expectancy.... like by half, or even more.
Don't get me wrong, I've done it..... but it's not "good".
