O ring size for the Garmin Mk2i spool.

Anyone have any links to these sizes above?
Looking to stock my save a dive kit without spending $300 for a couple sets of caps/spools

Hi!

I’m also looking for a spare Oring. Do you now if the 3,3mm is the outer or the inner diameter? I’ve looking and almost all specialized Oring sellers give the Oring sizes like this ODxIDxT (Outer x inner diameter x thickness)

Any help is really appreciated.

Thank you!

I found this shop that sells some o-rings as a set, just ordered 4 sets to have on hand.

When you receive them, I'd be curious whether they're the correct sizes. The Motor City Scuba (MCS) page includes a screen shot of Garmin's page ( How to Service a Descent Transmitter | Descent™ T2 Transceiver | Garmin Customer Support ) which lists 3.3 mm ID x 1.0 mm CS and 1.5 mm ID x 1.5 mm CS as the correct sizes, but the MCS part number is "1x2.3mmNBR70" (not that a part number necessarily reflects anything at all).

Please let us know, as these parts (the o-rings) aren't available yet through the Garmin online store. The 3.3x1.0 can be sourced through McMaster Carr, but they (and many other suppliers) don't seem to offer 1.5x1.5's.

If you reach out to support they can create you a "purchase link" to get as many as you need. I was able to order them rather quickly actually. Last time I did this it was right after the T2 came out but its the same o-ring kit in any case.

Excellent! Good to know. Thank you!

I've spoken to Garmin Support 4+ times over the years for issues ranging from my brand new T2 transmitter never powering off to small things like wanting some $2 o-ring kits for the save-a-dive kit. I can't speak highly enough about how they've taken care of me every single time.
