    Harbor freight has bulk O-rings, you can match them up with what you have.

    Not as cheap as the hardware store, but if you call Lyman they'll sell 'em to you--- and you don't have to drive into town to get them.

    OK People. Enough of this idle chit-chat.

    Most Ace Hardware and farm stores should have them. I carry in my old ones and match them up. hc18flyer

    Think I got mine at Ace, but any well stocked hardware outlet should have them. The brand on mine is DANCO and are labeled #35. They come 10 to pack. If you can't find them locally PM me your address and I'll send you a couple.

    I bought mine from Ebay. Brownell's also carries them. They are not one of the usual stock sizes. I've got both metric and SAE o-ring sets, and nothing I had fit them properly. Though I see others say otherwise. Some of my sets are quite old, and been picked over for years. YMMV!

    McMaster-Carr, if all else fails. They'll have the right size, and you'll get 'em in less than 48 hours, but that shipping is expensive.
