As an aside, you can download an o-ring sizing chart from Captain O-ring

Take it with a grain of salt, especially with old abused rings, but I was able to get within +/-1 size of reality

That's exactly how I found all of the other MacDev sizes, only size I still need it the valve stem/reg seat. It amazingly was the only seal in good shape on the LPR, everything else has already been replaced, I'm confident the LPR will work now but I am unsure of how much life this seal reasonably has left because of its age. I've emailed MacDev about it, we'll see what they say 😊

That looks suspiciously like the reg seat for a Tickler.

Check autocockerparts.com for the part.

MacDev just got back to me, its a proprietary seal that is pressed into the valve and is non replaceable. They still have complete assemblies for $6. They wanted me to ask if anyone else needs them to keep international shipping cost down.

So who needs/wants one?

I'm sure you can pull it out and replace it with something available in stores ...

You really can't. I'm 99% sure Macdev LPRs are identical to the smaller WGP LPRS (pretty sure WGP ripped of Macdev not the other way around) and on WGP LPRs, those seats are pressed in such a way that they cannot be replaced. I cannot explain why, I just know that it cannot be done.
