Trying to find O ring for Mira 723 and not a whole service kit

[Caveman]

Hi Everyone,

Does anyone know where to find out what size the O rings are in a Mira 723 service kit as I have one (at the pointy end of the piston/spindle) that keeps failing and I cannot afford to keep spending £23 to get one O ring. It is part "G" on the 723 instructions. Any help very welcome.

Either ask Mira, or buy one last service kit and take all the dimensions from that o-ring before you fit it.

Thanks BenGee. I've tried that and tried some generic O rings but without much luck which is why I'm trying to grab an actual size.
