Not all hydraulic hoses are the same

I got a 7 ft hose and armor sleeve for $46. Made in minutes.

I doubt if you could buy this hose in the USA without having it costom made. It has British threads.

What kind of threads are on tractors made on other countries?

Oring face seal (ORFS) is becoming the standard world wide.

German DIN style are somewhat common. Similar to Swagelok.
 
My Asian hang-on backhoe uses NPT thread and JIC fittings. My MGB, of course uses British threads on oil cooler lines and such. Of course they say the MG motors are tractor motors.

Why is the one you had made "in minutes" , not considered custom made?
 
The use of BSPT hose couplings on US-made equipment intended for domestic sale would be really unusual unless it was to connect to a foreign-made component for which there was no other port option. BSPT and NPT are very similar, so similar in fact that the two can even be (sort of) threaded together but the joint will not seal and the threads could be damaged. This is a big reason why US manufacturers avoid using BSPT - it's just too easy to mix up with the NPT that is so common here.
 
Not sure if I'm sold on that covering ? I have had several with that on them get holes rubbed in them and it really makes it harder to tell where the leak is coming from.
I used to have an old backhoe and several of the hoses were worn down or the outer covering was ripped off to where you could see the steel braids and they were not leaking ?
Hose likely is not made as good as it once was either.
 
I expect you can buy that hose here in the USA, not custom made, if you go to your Kubota dealer and order it by part number. If you are asking about buying a hose, not custom made, do you mean like the premade hoses with NPT or JIC ends, like you find at Surplus Center, TSC, and other places? I expect the reason you don't find them with every end thread made, is because the volume of sales isn't there. NPT and JIC have been common, in the USA, for years so there is demand enough to make and stock hoses with those ends in some standard lengths. In the UK you might find similar stock metric hoses with BPST, would be my guess. Another area of the world may have stock hoses with the ends common to that area. Supply and demand principal.

As far as what type fittings are used on different tractors there are many, NPT, SAE O-ring boss, BPST, and several others. One has to be sure what threads are used on most newer equipment because of worldwide manufacturing and importing of goods. Good hydraulic shops have to have a large variety of fittings to meet the needs of tractors/equipment and industrial/manufacturing machines.

The hose is routed under 2 cylinders on the boom .it took 17 years to wear a hole in hose. I may not be alive in another 17 years. I may not be able to keep going much longer. This terramite has a little over 2000 hours. Many hoses have cracked already. This was my only choice. No enough space for the other sleeve. Nice chatting

I'd dispute that, ORFS still a niche product depending on the industry you work in. The DIN you are talking about are flareless compression style for metric tube. There's a similar one for SAE tubing. Also still niche stuff in general.

In agricultural equipment still seeing the full unstandardized range of fittings. More annoyingly some new stuff coming with cheesy proprietary push to connect stuff that is impossible to find replacement ends for.

Pull my hair out trying to maintain European built farm implements with every manner of weird fitting out there. Best thing I've found is the various metric to JIC adapters sold for a couple of bucks, can usually take out a metric fitting and thread these in. Turns a 250$ metric hose replacement into a 50$ JIC hose.
 
Kubota LA loaders built in the US with US style hydraulic fittings. In Canada the Kubota loader is a Quicke/ALO depending on the age and joystick selection, any of a 4 or 5 different metric fittings.
 

That would be an excellent price for my area. First hose that busted on me, I took to the local hose shop. About a four-foot hose ran me slightly over $100. No sheathing, just fittings.

Thinking I might have gotten hosed (sorry), next hoses I replaced came from TSC which is close by. They ran around $20 each. They also have the fittings and adapters. Everything is tight, no leaks.

The covering is not intended to offer protection to the hose.

It is a containment covering, designed to stop a leaking hose from spraying on people or anything it might damage or cause a fire danger.
