So far I've tested the Dupont Krytox GPL205 grease, the international version Ultimox 226 which contains extra wear and anti-corrosion additives, and now the Dupont Krytox GPL 105 oil and all have worked splendidly!For me anyway.....gone are the diesel prone black staining molly lubes!

Thanks, Ed. You are a big influence on my decision to go with an o-ring and Krytox. I read your posts about o-ring piston seals and Krytox with interest. You have the advantage of access to machine tools I do not have though. I do not use Krytox 105, I use 106. Probably very similar. I get Krytox 106 on my job, it's used in medical devices on bearings that operate under very high heat and pressure. I still use moly paste on spring ends. I have gotten away from using velocity-robbing spring tar. I also like moly paste mixed with Mobil1. I keep both of these lubes away from the piston seal and may we never experience dieseling again!I got a kick out of seeing your o-ring B3 piston. You must've gotten lucky and had a pretty nice compression tube to begin with. The one I have was badly rusted and pitted when new, right out of the box. I honed and polished it until it was oversize but some pits still remain. I used a ARH Tesla seal and gained more than 150 fps over the original synthetic B3 seal.Are you experimenting with dry lubes like molybdenum disulphide or tungsten disulphide?
After reading this thread I ordered an oring conversion and hope to assemble my 45 soon. Does your 45 have any spring twang?
I have a '85 model 35. will vortek seal kit fit this gun?
what should the spring be lubed with?
I don't have a problem with the upgrade you did to the piston seal because you made it better. I don't know if old or antique air rifles are going to have any value beyond what they have today? The one thing I do know is they will have no value if they don't shoot. I think you did good and that air rifle will be shooting for decades.I have a question for you. I'm probably going to have to tear down the Diana model 35 I have. What did you run into when you removed the trigger? I have read some about the model 35 I have and the three ball bearings in the trigger. Did the trigger on your rifle have three ball bearings and how hard was it to take apart and put back together?Bryan
