Timing two sets of threads such that everything lines up correctly will be nigh on impossible. I use a captive o-ring setup with my hipac in place of the ones supplied with the unit..very similar to a bonded seal/washer.

Have had zero issues with them, but I leave them in place.

Might be worth looking into if you're having issues with the seals.

The question is do you have enough threads at the tube end (exposed theards showing) to engage threads into the valve front? If not then you will need a different plan.

As stated in an earlier reply, there would be no need to have threads engaged at all where the hipac threads into the tube, once it is securely connected to the valve. But since there is already threads there, it is simply a matter of threading it in loose until the TP and valve retaining screws line up. In my case where the hipac will need to be about 3/8" farther into the tube, I will need to remove that amount from the tube end.
The project I'm considering for this particular gun is or might be a one way experiment. By that I mean, if the internals of the valve ever fail, after i have everything in place, then removing the valve for replacement or
repair, would be difficult or maybe even impossible.
The captive o-ring makes good sense, but, then there would still be pressure issues on the valve retaining screws and tube end where the hipac threads in. By connecting them permanently, all the air pressure is contained. Thanks for the input.
