Use end tap so the thread is not tapered and/or taper the bolt too. If you drill a suitable grooved/tapered flat surface on the connector face for o ring there is not much force required. Compare it to bleed screw which are usually destroyed by over torquing when the o ring does the job and very low torque needed.
