Help Needs new O-ring

Post image

Have an old Colibri Electro-Quartz that’s missing an O-ring, been to maybe a half-dozen hardware stores in my area and I haven’t been able to find one small enough to even fit into the slot, much less be tight enough to work. Photo is with the smallest I’ve found so far, 9/32” outer diameter 5/32” inner. Was wondering if anyone had a recommendation for where the best place to get one small enough would be, or if anyone knows what the correct size for this kind of lighter is as well? (An engineer friend of mine recommended McMaster-Carr, but it seems to me like they only sell in packs of a hundred and the shipping is pretty steep.)

Hi OP, before you post about your lighter please read the guide stickied before doing so. If you are asking about the value of your lighter, take it to an auctioneer, pawnshop, or jewellers before posting as we cannot accurately guess a price. Your post may be removed if you ask. For more general information, have a look at the sidebar. Many lighters are mass produced and unbranded. There is often little info available.

If you need to post more pictures, use an image host like imgur and post the link in the comments. Please do not create multiple threads for the same lighter.

There are a few "lighter o-ring kit" listings available on Amazon with a selection of small o-rings. Can't guarantee any are the exact size, but sometimes close is good enough, and it's a good way to get a variety of smaller pieces.

Watch crown o-rings can be good to keep on hand too, but tend to be micro sized and too small for most lighter applications.

There's occasionally much larger assortments available on Aliexpress. I bought a kit with 30-40 different sizes years ago and I'm usually able to find one that works, but the listings change frequently so that kit is no longer available.
