External filter mount thread size

Post by 65splitpanel » Tue Dec 24, 2019 4:53 pm

The centre fitting that came with my sandwich plate is 3/4-16 UNF however, this does not fit the centre fitting on my external mount and also is not correct for my filter (Mann 940/1). Making it more infuriating is that the filter allegedly IS 3/4-16.... :?

Anyone know what size thread the centre fitting is on the common external filter mounts we use?

Sorted this now. Thanks for the views. The fitting is M18 x 1.5
