Does anyone know where to buy a replacement o-ring (larger one) for a 294mm pro?
SteveD The outer diameter is 32mm, and the wire diameter is 1.5mm

I'm not referring to the window o-ring, but the one that is behind the front plate. It is much larger than 32mm.
SteveD The larger o ring outer diameter is 67mm, wire diameter is 2mm
