I have a newly installed diverter kit installed on a 5075e. It came with 2 female ag type couplers installed on the front of the loader. My grapple has the flat faced couplers so I have to switch out one or the other. I decided to go with the flat faced mainly cause I always forget to use the covers/plugs on ag style and they are cleaner. I got to looking at the ag style on the loader and can't find any flat faced with same configuration.

The female couplers on the loader have a 1/2" male pipe out the end that goes through a hole in a metal plate to mount them on the tractor. A swivel nut on a steel line then connects to the threaded end. The pipe is not tapered, a jamb nut is used to mount it to the plate. The pipe out the rear of the couplings appears to be a permanent part of the assembly/ not screwed in the couplings. What I bought is a set of flat faced couplings with 1/2" female threads. I cannot figure out what I need to use these and can't find any that have the male pipe built on to mount to the plate with the hole in it.

After seeing this, I thought I'd just go with the AG couplers and I already had a set of male pioneer tips to install on the grapple. I removed the flat faced couplers from the grapple which appeared to be 1/2". However, even though the threaded end of the hose appeared to be the same as the AG coupler, it would not thread on. It must be a different thread pattern than a normal 1/2" hydraulic hose? Metric maybe??

So at this point, I need more parts but not sure what I need. I think I'd still like to go the flat faced route if I can get the parts I need to solidly mount to the loader in the same way the ag couplers are mounted now.

if they are not tapered they could be BSP or SAE fittings. if they are not tapered and have a flare, they could be JIC. you should be able to find a bulkhead connector with the extra nut on it.

They aren't tapered and don't have a flare so maybe BSP or SAE?
