My point was that cast iron is possibly not a good choice over brass
in this context, because of corrosion, rust stains, etc. Also, most CI
fittings are tapered thread, and I think parallel is correct here.
The term iron on the screwfix item doesn't mean thay are actually made of
iron.
It just means they are compatible with the older iron threads.
They are made of brass.
