An M25 to PG 16 thread adapter will not be compatible as it does not have the same thread type characteristics as an M25 to 3/4" NPT thread adapter. A PG 16 thread size has 18 threads per inch, while the 3/4" NPT size has 14 threads per inch. Also, NPT threads are tapered and are at a 60 degree angle. PG threads are not tapered, and are at an 80 degree angle. PG threads also have a smaller thread depth than NPT threads. If a metal one will work for you, we do offer a nickel plated brass M25 x 1.5 to 3/4" NPT adapter, part number AM-2534-BR.
