Hi all, totally new to the forum, it's looks full of information to help with my first divelight project.
I've had a bit of a trawl through but can't seem to find O ring upgrading information for maglites. I need to find out all the inner diameter o ring sizes of a D cell maglite and the suggested thicknesses to help waterproof the tailcap and bezel for diving purposes, hope someone can share this info. I'm in UK so metric sizes would be gratefully appreciated. Thanks.
