It's a 6AN thread on one end of the adaptor, and M14x1.5 (definitely not a tapered NPT thread) on the other end.
The thread on the Bosch filter is a matching female parallel M14x1.5 thread.
Hence my concern that the adaptors won't seal without (Nitrile) O-rings.

The two adaptors (ie one for each end of the filter) are identical, and the threads on both ends of the filter are identical.
