If you are referring to the QD fittings, Kubota uses Pioneer style.

The fittings on the BX2380 are not Pioneer style fittings. They are flat face connectors. My quick coupler leaked. Had it fixed under warranty. Began leaking again. (Yes, I always kept it very clean!) Replaced the female side (loader side) of the coupler with 4, 1/4 NPT flush face Summit hydraulic couplers and 4, 3/8 JIC to 1/4 NPT adapters. Hasn't leaked a drop since.

The loader cylinders are #6 ORB. They have an adapter fitting that connects to the #6 JIC on the hose end.

That's sort of what I figured. I don't have the tractor yet but, will have it Saturday. Being a mechanic, I like to keep some spare parts for just about everything I own so, I figured I'd get a few length hoses made and just keep them on the work bench. Just in case. This will be my first tractor bigger than a lawn tractor. Thanks for the heads up on the ORB fittings, at the cylinders, I'll probably get a few spares of them as well.

New to this forum i had in mind to change all the hyd hoses on loader lift and tilt, tried all the Smith hardware farm stores in my area tried TSC all have 3/8 pipe which is one end and all the swivel fittings i tried are to shallow 3/8 being to small and 1/2 ti big, but it does not matter all Kubota fittings are metric swivels i checked these out personally i was a machinist for 38 years so have the knowledge to check sizes and thread pitch. Mine happen to be M18x 1.5 threads per inch. Now i have found some still looking but one swivel connector is 20 dollars i am wanting to change to new hoses already made to get away from oem set up. Does anyone know a good place to buy kubota hyd fittings? By the way i own a Kubots L3940

I make my own hydraulic hose for my 2 Kubota tractors, m6 141 and m100. On the new m6 the loader cylinders fitting are called British Standard (BSPP) on a 3/8 hose. Some are a 90 degree and some are a 45 degree. In my Eaton catalog for the fittings the series number is 06Z-76P. And the other end is the WEO plug-in fittings. You can look up the WEO fittings on a the company website CEJN. My tractor use the 147100806 which is 3/8 hose and a 1/2 inch quick connect. My father's Case Farmall use a 3/8 hose the BSPP fittings but the quick connect is a 3/8 and not the 1/2 inch.(#147100606)
Note, the BSPP fittings look very similar to JIC fittings.
Hope this helps

So I did exactly this but all my fittings are leaking. I used thread dope, stilll can’t get it to stop leaking. Any suggestions?

It’s hard to tell. I think it’s the tapered joint but I’m not 100% on that. Everything has oil on it after I run it for a few minutes.

If you have matching fittings and and use a suitable sealant a tapered pipe joint will be pressure tight. If its not pressure tight you have miss-matched fittings, poor quality fittings (unlikely with steel hydrauluc fittings), or improper assembly.
