Question Backscatter MF-1 o-ring size?

[jbarry_underwater]

Looks like backscatter only offers the o-ring kit for the MF-1 and MF-2 strobes which includes the silicone grease. I have plenty of grease and just need a couple o-rings, does anyone happen to know what size they are? Thanks

Friend if you put the oring down as a circle on a white piece of paper and then
measure the internal diameter then the thicknes with a ruler you have your size

If you can squeeze the rubber with your thumbnail, it's a 75 duro or something

Thank you, I was hoping for something more precise as I don’t want to risk flooding if I don’t get it exactly right

well that's how they do it at the oring shop and then they put one next to the other and voilà
