Hi everyone, Since I got my Primus Omnilite TI, I cought the bug of liquid fuel stoves. Being from the former communist bloc, I said to myself why not start with the soviet clone of the 8R. A few days later, I became the (potentially happy) owner of a Primus PT-1 stove in like-new condition. The stove worked *almost* fine during the test runs, but soon I discovered that the original graphite packing was in bad shape - and leaking. I tried to tighten the nut, but to no avail. Therefore, I see myself force to replace the graphite sleeve. I tried looking online for a direct replacement, but I couldn't find any. For those of you who who worked on this stove, does the graphite packing have the same dimensions with the Optimus 8R? Or should I look for a different solution, such as graphite tape? Any suggestion regarding the materials I may use will be greatly appreciated. Many thanks!
