New attachment... not certain of necessary coupler parts

[ning]

I grabbed one of those front-end hydraulic tree/shrub puller (shrub, in my case, or very small trees) at auction last week.

I have a "third function" diverter set-up on the front loader; as far as I can tell, it's set up with 1/2" ag connections; the grapple I recently bought from WRLong has QCIA8M-8MORB ("1/2" m/f Ag Quick Coupler for 20GPM valve) and it works fine.

The auction attachment came with 3/8" hoses and flat-face connectors, so I need to swap connectors but I'm unsure of exactly what I need.

Here's what was on the end of one of the hoses:



Hose dimension:


Adapter on the right of the coupler pic:




I saw this
Summit Hydraulics 1/2" Ag ISO 5675 Hydraulic Quick Connect Tractor Couplers, Ball Pioneer Style w/Dust Caps, 2 Sets: Amazon.com: Industrial & Scientific


but that's NPT so guessing it won't work.

Will this
1/2" Ag Quick Coupler Set (Q/COUPSET.500-ORB)
"Male & Female: 1/2" Body with 1/2" Female SAE O-Ring Boss Threads"

WRLong wants a ton of money for shipping on that so I'm looking for an alternative.

The end of the hose has a female M18x1.5 DKOL fitting. The adapter in the 3rd and 4th picture is a male M18x1.5 on one side and male 1/2" BSPP on the other.

If you can find a 1/2" Coupler with 1/2" BSPP thread, it would be a matter of simply swap the flat face coupler with the new one, using the same adapter it already came with.

If you can't find the couplers with 1/2" BSPP thread, then you can get the ones with 1/2" NPT and get 2 of these adapters: 5007L-12-08 | DIN 2353 L (M18x1.5) X 1/2" Male NPTF

And the couplers: ISO 5675 Agricultural

Not sure if you need 2 Males or a Male and a female, so I leave that link instead.

The adapter has an o-ring on the coupler side, are you sure it's BSPP?

Yes. That's what seals against the face of the flat face coupler (in this case) or a port on a cylinder or valve block.

Right, I confused it with BSPT, thanks!

I think these should work then:
