Nitrile or Buna N will be fine with acetylene, not sure about oxygen. Buna N will not work. BTDT. They last about a week. 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. Grant FOLLOWUP: Victor apparently uses Hypalon - chlorosulfonated polyethylene - O-rings according to an old "Welding, Cutting & Heating Guide" (ca. 1969). - GWE |
