Good place to order orings from?

I’m looking to order some o rings. I need a size chart and good place to order from.

I’ve been getting mine from Fasttech, but their selection is limited to one thickness so far. I think I have most of the black ones they currently offer. I’d like to see thicker ones for lights that have a deeper O-ring channel.
No idea on a size chart, I just measure them and try to get something close.

Welcome the night.

If using for waterproofing on flashlight threads, i recommend buying slightly smaller then the diameter so it will have to stretch slightly so it doesn’t become a loose wobbly pita

I am currently extremely busy with work. Please do not expect a response from me quickly. I will be dropping in as time permits, but the amount of time I can dedicate to responding to topics and PMs is very limited.

McMaster-Carr is where I buy a lot of miscellaneous parts.

If they don't have the o-ring you want than no one will.
