Sealing a Maglite C cell

ofni · Feb 23, 2014

hello

I have a C-cell Maglite and I want to make a diving flash light. but I don't succeed to find the correct size of the oring to seal the tail cape. I have tested a 25mmx2.5mm o-ring but is is definitively to thick.

Have you any suggestions ?

I would use JB Weld and just seal it with it. Once the hole for the gland is in, you can use that to run the wire in and out, do your soldering and then use the gland as your cap. I tried to use the C mag but ended up doing that as I too could not find o ring

ok thanks for the advices.
I not very happy with the fact that this operation is definitive but if there are no other choices....

have you already tried a silicon mastic instead of JB weld ?

I use the stock oring and then seal it up with aquarium grade silicon
