Fenix o-rings

Does anyone know the original dimensions of o-rings for the P1D-CE and P1D-CE Q5 (if different) and also the L0D and L0D-CE Q5? (once again, if different) Or sizes that will work for sure?

I finally found my old boxes for my P1D-CE and L0D and came up with I.D.'s of 1/2" and 3/8". (~9mm and ~13mm)

First I emailed FenixStore and they say they don't have the information. I've also searched CPF and still haven't found anything definitive.

Many thanks and if I somehow missed this in my search, sorry!

The only changes between those respective models was the emitter. The circuitry and body remained unchanged.

Thanks for the reply & 411.

I found my newer boxes. The L0D Q5 o-rings are the same size. The P1D Q5 o-ring looks a tiny bit thicker (32nd) and more like an I.D. of 9/16" - 5/8". Seems like the Q5 version has to be lubed more often so that'd make sense.

I'll probably buy a sample range of BN70 type. I guess it's not that critical.
