I was hoping to be able to use a generic oil cooler with AN or NPT fittings, while having hoses configured with the appropriate fitting to the sandwich plate, which I believe would be BSP in the case of the JH original or the Mocal replacement.
It's my understanding that the fittings are 5/8 BSP, and I was having difficulty translating that to NPT or AN sizes.
This just caught my eye.
There is no translation of threads from one system to another. BSP (British Standard Pipe thread) is not compatible with NPT (National Pipe Thread) is not compatible with AN (Army / Navy thread) is not compatible with... There is a myriad of threads out there, and for each connection you have to find the correct parts. It is not possible to mix and match, even if you were able to get the parts to mate the connection would leak.
Your observation is, undeniably, completely correct.
