Underwater Camera Cases & grease for o-ring

    I have one a Canon Elph and the matching underwater case. Unfortunately, I have misplaced the tube of lube that came with the case. I believe is it silicone grease that is used to lube the o-ring seal to make the case water proof.

    I had read online that you can by silicone grease at a hardware store. I sent my husband and he came back with something called "white lithium grease". can this be see with my canon underwater camera case? I a going on a trip to the Caribbean in a few days and I want to make sure I have the right stuff.

    can white lithium grease be used? Or should I try to find silicone grease?

    thank you!!

    do not use lithium grease. it will degrade the silicone. use a water based lubricant. in a pinch, a little KY liquid can be used.

    Do NOT under any circumstances use a water based lubricant. That is shockingly bad, incorrect advice!!!

    Go online and order some silicon grease with next day delivery and you'll be good to go! Have a nice holiday :)

    I must have messed up. can you explain why? I always thought you used water based lubricant with rubber parts. thanks

    Silicon is best for cameras and torches as it's thick (best for keeping water out) and almost completely inert which will keep the seals in top condition. Paraffin based lubes such as vaseline are a bad idea as they can degrade the polymer parts of the seal.

    Telling someone to use a water based lube with almost invariably result in them rubbing something like this into their ring rofl


    You're right, specialist water based lubes are fine for rubber, a bit hard to find though - my reply was partially for the lols but also to avoid the lovely lady rubbing durex into her crevices and then wondering why she was leaking ;)

    cool. good to know. I have a silicone spray I have used for other things. I have never lubed any of the O rings on my cameras. just kept them clean and dry. might think of getting some silicone grease for them so. cheers.

    The normal black o-ring on my old camera (silicone grease any type)
    but an Olympus housing on my new camera had a soft coloured o-ring and had a specific grease to use with warning of damage if wrong type used.
    sea and sea grease a yellow tube had different coloured caps for the two types of o-ring grease.
