Can any of you Gasparin CO2 motor lovers give me the specifications for (or help me locate) the piston 'o' ring for this remarkable little motor? Everything else seems gas tight but when the piston pip hits the valve the gas escapes past the piston.

At those sizes, you're probably better getting them from watch repair shop suppliers. Nitrile O rings will be fine.

Hi. Yes, they can be difficult to get.  Embarrassed Watch repairers is the best source. If you are unable to source any locally I might be able to help.

Don't suppose you can help with o ring sizes for a telco. I did ask for help in a seperate post for this, but when I re-read it I wasn't real clear in my request for assistance.

Finally managed to track down some watch crown seals on eBay that seem to do the trick. Never realised you could get o rings this small.
