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:

Every time I buy a kit like that, most of the couplers won’t fit my setup.
Usually by starting at the cylinder and plumb the hoses to fit my stuff that I can get at the local NAPA works best for me.

Hydraulic hoses and fitttings are getting pricey so I try to make every connection as simple as possible.
One of the local parts stores will cut your good hoses and put new fittings on. This really helps to make hoses the same length to connect without that extra loop of hose that gets in the way.

Surpluscenter.com has a catalog with pictures on types and charts for sizes. Good for reference . I used to buy from them but yesterday I went to a diesel shop with a hyd hose shop. An order of 8 fitting with shipping was $40 at Surplus Center and 3 or 4 days to get. And if they are wrong … more time. At the diesel shop they $21 for 10 fittings in my hand that worked.
