Question Apeks tool AT72

[buddhasummer]

I have this tool, it uses two O rings one is a -010 I'm almost positive. The other I have no idea, my micrometer is playing up so cannot measure it. In the photo below I've put a DIN O ring next to it, the DIN O ring is the bigger one.

I reached out to Apeks but got no reply.

Anyone any ideas?

Thanks muchly.

I don't have that tool, but I can say I've had good luck sizing orings with the printable guides. One that I keep going back to is: Support/Manuals

Check a known oring to make sure your printer didn't do something wonky, and then good luck!

Thank you sir. It's not any standard O ring used by Apeks on their regs or any common O rings used by SP, I have a lot of O rings. Seems it's unique to the tool.

Cannot tell for sure, try to place a scale over it. Is the cross section the same as the -111? If so, My best guestimate is a -109

Just trying to find a printer to use.

Just trying to find a printer to use.

You can also try downloading the pdf on a tablet/phone, zooming the image until it matches a known oring, and then do it that way. Probably easier on a full sized tablet than a phone.

Thanks Jim. Big brain. I'd have never of thought of doing that.

Thanks guys.

Drum roll.... the winner is @couv.

I did as you suggested Jim using a -011 as reference, 99.9999% it's a -109 as couv guessed.

Amazing.

You know what's coming @couv.
