I looked at mine I used 3/4 electrical conduit grey pvc,
not 1 inch like I thought

Ok, so replying to my own thread in case anyone ever searches. I was able to source a rebuild kit from John @ North East Scuba Supply (someone on here pointed me in the right direction).

The allen threads inside the isolation the isolation manifold are reverse threads. No one anywhere knew for sure if they were or not. Man they were really in there. Cold ultrasonic, then hot, then cold again with 40/60 vinegar / water and they finally cracked loose in a vice with a hammer. A little this way and then that way.

No loctite residue, so I didn't use any putting it back together.

John's kit came with everything I needed. I also got new burst disks because why not.

Plus side is the valves glide super easy in either direction. They weren't hard before, but there's definitely a difference. I can see why these manifolds aren't as nice as the newer valves with the o rings in the barrel. As you can see in the 1st picture up top a lot easier to gum up the o rings sealing on the face than the newer style.

Another thing is my manifold didn't have any copper crush washers in it. I'm not really sure if they're needed but they have them now.

Thanks! Your post confirms that I'll use North East Scuba Supply for a "kit" on mine.

NESS is awesome, he has just about anything you could ever dream of needing and some stuff you didn't know you needed, lol.
