O-rings specifications for Seac Sub Q1 and Q5 torch lights

[laffrey]

I have 2 Seac torch lights: a Q5 that I use as main torch and a Q1 that I use as backup.

I need to replace the O-rings on both of then as they have not been changed for quite a while and I want to be on the safe side
I have searched on the Seac Sub website, internet and various boards However I could not find any document .that contains the specs for these O-rings.
I have also contacted Seac Sub in Italy to no success. They said they do not have that information...and recommended to go to a Seac Sub dealer (there isn't any where I live). I have contacted Seac dealers in neighboring countries and so far, they could not help.

Would someone be able to help with the detailed specs / dimensions of these O-rings?

Q5 torch:
- double o-ring radial seal: ???

Q1 torch
- double o-ring radial seal: OR 2150 NBR (37,82x1,78)
- on/off switch seal: ???

Thanks

I used to go to the seals and oring shop German guy very technical factory and a diver
anyway his staff would hide when I came in every few weeks with a dozen unmeasured

But what happened is I liberated myself learnt to measure and read and became happy

Thanks @happy-diver. On this web site, they sell O-rings by 100s and the FedEx shipment would be over USD 100...
However, there is useful information and the Olypsys measurement app for O-rings is very effective. I downloaded the User grid, calibrated it on the app and measured my O-rings. That worked fairly accurately.
