Why don't you just go with a 3/4" bulkhead and a adaptor 3/4" threaded to 1" PVC slip?
The bulkhead would have to be 3/4" threaded on both sides to accept the loc line fitting.

Ok but will a 1 inch bulk thread x slip have a 3/4 inch thread on flange side

No, you will need to buy a 3/4" bulkhead, both sides will be threaded...
