The O ring for the VT3 hatch is a regular B026. You can get it at any O ring retail store. I do not know the O ring size for the transmitter (cause I´ve never had the chance to play with one of those yet). But I think if you open the transmitter up and take it to your local O ring store, they´ll measure it an sell you a dozen for less than 10 bucks. Post the size of the transmitter O ring size when you find out.

I'm not 100% sure, but I don't think AS568B-011 is the correct size for the VT3 transmitter battery hatch. According to Scuba Diving O-Rings - The Scuba Doctor, 011 has an 0D of 7/16" and is Standard Low-Pressure Port/Hose (3/8" UNF). The transmitter hatch o ring is well over 1/2". Thread Oceanic VT3 O-Ring has it at 016 and I'm pretty sure this is correct. This thread is very old, but hopefully I can keep someone from buying the wrong part.
