InTheHighlands Posted January 8 Share Posted January 8 I wonder if anyone happens to know the O ring size for the ports on the AOI/Olympus housings for the PEN series of cameras? By measurement, appears to be 76mmID x 3.0mm cross section - but I wonder if AOI/Olympus would use standard metric O rings, or JIS standard? Closest JIS standard would be 74.4mm x 3.1mm. Answers and thoughts appreciated! Link to comment Share on other sites More sharing options...
AlClarence Posted January 9 Share Posted January 9 AOI list them as 74.4mm X 3.1mm here https://www.aoi-uw.com/aoi-por-02.html Link to comment Share on other sites More sharing options...
InTheHighlands Posted January 9 Author Share Posted January 9 Excellent, many thanks - although this means I've ordered the wrong size........! And, I'm pretty sure, the ones supplied with my AOI / Zen ports are not silicone........ Link to comment Share on other sites More sharing options...
