To secure my blow down tube i need a need a straight fitting that has an -8an on one side and a 1/2" npt on the other side. Using a steel braided line as my blow town put so the 8an connection on the one side is needed then drilling through the floor and using a bolt to secure the other side. I know amp sells them online but not heading out there and everyone else wants 8 dollars shipping for a 6.50 part that weights a couple ounces
