  • Just an O-Ring.

    posted by stronge

    They DO fit an Ultrafire C3 perfectly although 20mm is the flashlight's outer diameter. I've installed this ring between the glass and the reflector and the bad head contact issues are gone now.
    It's a pity there's only 20-pcs pack as I'll hardly use them the next decade :). A 5-10 pcs pack could be nice.
    Buy SKU.5678 or SKU.5648 instead at half the price, unless you really like the color.
  • Well made

    What's to tell? They're well-made silicone o-rings. Use them to increase water resistance of flashlights, or as spares for those worn out, rotten, or split o-rings.
    These rings may conceivably be used in areas that are 1-2 mm wider.Only use these with a lube gel that is silicone safe!
    Those heavily involved in flashlight DIY-ing should get these in every size.
  • Great price for a lot of O-rings

    - Well what can you say about O-rings?
    - Well they are O shaped with no beginning or end;
    - Very cheap;
    - A lot of O-rings in one package;
    - Good to have some spare for your led flashlights
    Just handy to have lying arround as spare for your flashlight.
    Seems to be the ideal size for the tubes of C3-sized (AA) mini flashlights.
    If you have flashlight where these rings will fit, buy it just in case because if you 'll need it you don't want to order it and wait one or two weeks
  • THESE ARE BLACK

    posted by tohellandback

    I think the other guy is dyslectic.
    he states that these o rings are orange, not black. Well take a look at the pghoto.
    It shows you an orange o ring so why tell time and again that this oring is orange, not black
    I got these orings and THEY ARE BLACk.
    i files a report at DX and they promised me that they would fix it.
    i told them the problem was because they mislabled the items. they put the correct partnumber 5736 onto orings which are black
    i received my new oring and guess what
    I GOT THE SAME BLACK O RINGS.
    i really hate it when i try to convince people that they are going to make a mistake and after al my trouble they just make the same mistake i warned them about
    DX please correct this
    you mislabled your stock and people are getting black orings and not orange ones
    if you need black o rings these might be ok but do not expect orange ones
  • O-Rings!

    posted by ace-at-mind

    Hey, they're o-rings...These fit pretty well for the large end of my 9-LED flashlights I got from DX. Nice snug fit, but could be a little tighter. They are made of some great feeling material, you can tell they are very squishy and will last a great while.
    Don't know what else to use them for. I bought them for my flash-lights. I imagine they are useful for waterproofing and threaded fitting of the 26mm diameter variety.
    if you need this size o-ring, or just want little orange rings, get 'em!
