I gave up on trying to make mine work before I even started on it for the same concerns of it leaking some time down the road.
What I did instead was take the guts out of the tube and soldered it all back together without any way for it to leak.
It is now just a fancy looking non-functional Rancho valve that will never leak and no one will ever know. (Well, except for the 10s of thousands of y'all now that I spilt the beans.)
