Hi all Recently I went to purchase some washers for attatching my D-D reg to an FE from my LFS. I thought Â£1 for two washers was a bit steep when I got them from him last time but now they are charging Â£3 for two washers so I didn't bother. I've tried sourcing the washers elsewhere and have come up with what I think may be a suitable alternative. As I understand it the material needed for pressurised co2 applications is Nitrile and the washers in question are flat 3/4"x 1/2"x1/8"thick. The washers I have found are Nitrile 19mm x 12mm x 1.2mm and flat, 50off delivered for Â£6.50, or Â£75 worth of the ones my LFS are peddaling. I know there not quite as thick (aprox 1.2mm instaed of 3.2mm) but would this matter? And would it be ok to just put a few of them on to make up the thickness required if it did. I think the two faces (Reg and FE) can be screwed together until they meet with no problem. I would be very interested in other peoples views / experience and if someone knows where I can source the exact size Nitrile washer that I need without being ripped off that would be a definate bonus. Regards, Chris.
