Fitting size?

Does anyone know what the thread size is for the oil cooler lines on the oil filter housing?

1/2 in. NPT

1/2 inch NPT into radiator. I think oil filter housing is 20MM. Just wanted someone to verify.

I don't think the radiator fittings are NPT. Cant remember what size but they take a flare hose.

Yep 1/2 NPT is little to big for radiator size and is not the correct thread for filter side.

The oil cooler lines go into an adapter before the oil cooler housing.

The oil cooler housing itself is 1/2" NPT.

The fitting into the housing is what accepts the hose end which is a saginaw I believe perhaps with an o-ring.

I get that one and the one into the radiator mixed up.
