help identifying chinese excavator fitting

[oldnslo]

I'm adapting a chinese excavator smooth face tilt bucket to my Kubota BH92 backhoe. MEchanically, it actually was pretty easy. I'll document that success separately.

Now I need to adapt the tilt cylinder hoses to common Ag couplers. Attached two pics. The first is the hose end. Can't really measure much about it. The second is the cylinder fitting. The outside thread appears to be a M18x1.5. The inside, where the o-ring seats is slightly tapered. The big end is 0.545" or about 13.8mm and tapers to 0.478" or about 12mm. I need to source an adapter that goes from the hose end to probably an NPT fitting.

Of interest, the other side of the cylinder adapter is an o-ringed M14x1.5 I can find a M14x1.5 to JIC fitting, but then, I need new hoses. The JIC adapters I could find were expensive as well. I did find a pack of 10 on e-bay, but I got an e-mail from the vendor saying that the o-rings were cracked and damaged and he will refund my money. Otherwise, I was looking $35-$40 for a couple of fittings including shipping.

Per an old Aeroquip fitting handbook that fitting with O-ring could be a DIN 3902 DKO style fitting. The hand book is 24 years old so very good chance there are other variations out there now.

The fittings are DIN 2353. Meant to be used with hard lines, however, there are fittings that go on hoses as well. Often these fittings use an o-ring to help seal the taper.

That looks right. So, I can use my existing chinese hoses and connect to ag couplers using this fitting...

Yes, as long as you get the right size of course.
