Best kept secret on Scubaboard - OrcaTorch O-rings

[munselln8]

I've searched and searched, read many (valuable) DIY O-ring posts (bought a bunch of O-rings), but I can Not for the life of me find any info on the exact size O-rings for the OrcaTorch line of torches. I have the D530, but I am guessing the D520 (at least) uses the same rings. Any insights from the group? Note: It is nice that OrcaTorch sells the 3-ring replacement set on their website, but $10 a pop is a bit much for me. TIA for any help.

Try here, measure them and see what you can match

Thanks for the link!! I was trying to avoid buying a micrometer to measure myself (I'm not a dive center trying to sell them or maintain multiple units - just a DM trying to reduce my personal maintenance costs) but, in the end I may need to...seems like this is one of the most popular brands in the recreational dive market and thought somebody might have already done it. Thanks!

I’ll dig out my D 530 and see what I think may be the right ones later, maybe tomorrow.

This looks to be the one

The battery is dead on my caliper so this is my best guess nominally ;j

3 rings used on the light.

so, do you mean the "measurement" is 20mm x 2mm? shouldn't be too hard to cross reference that...Thanks!!!

To be super clear, that is 20mm ID, 2mm Cross-Section.
