does anyone know what type of hydraulic fittings come on the new bx2380? Are they standard JIC fittings or something else
Hydraulic fittings
- Thread starter Bullock
- Start date
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.
I was actually referring to the threaded fittings at the cylinders etc. I see the are an 11/16 " wrench size so, I'm pretty sure they are #6 JIC

Most OEM cylinders use ORB (o ring boss) fittings or ORFS (o ring face seal), I'd be surprised if they are JIC.
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.

Sounds like a thread and/or fitting mismatch to me if "all" of them are leaking.
Check out this online guide to identify a hydraulic thread type/size in 4 steps.

The most common cause for leaking hydraulic fittings are mis-matched threads.
