Don't know about nitrile but looking at the specs and figuring that it was oxygen (both o-rings are exposed to oxygen while only one to the acetylene and both went bad at the same time) that did them in and looking at ozone resistance I went with Viton when I ordered mine for my Purox torch. I got 100 of them from MSC several years ago (more than a lifetime supply but the smallest quantity they sold them in). Yup, I've finished my research. Viton in size 006 and 010 will fit and work OK for Victor 100 and J-100 handles. Thanks everyone. In case you want to see a picture of a crappy O-ring I took off a torch, see the pic: http://www.tinyisland.com/images/tem...ictorOring.jpg That one was flattened, cracked, and splitting. Incidentally, the tip still worked OK, go figger.

I must say though that the Viton rings are holding up just fine for me. I don't think I've replaced one in several years now that I've gone to them. The Buta-N rings wouldn't last a month when I tried them. |

I use Purox torches and parts are hard for me to find. Thus I ordered a package of each size from MSC years ago. With 100 in a pack it's going to be a long time before I need any more. |
