O-ring for Revolve Gen II

[BindlestiffNYC]

I'm sure the info is buried here somewhere. Sorry for not being able to find it!

I need to replace the O-ring that keeps the Secondary Cooling Unit locked into the the DRC Airflow Tube of my Gen II Revolve:

Can someone tell me the measurement of that O-ring? I think it may be slightly smaller than the Revolve's other O-rings. Thanks much!

If you buy the Revolve O-ring Set, you get 8pcs 6x1mm and 2pcs 5x1mm...so I would say 5x1mm

Greatly appreciated, MrGreenspoon. Thanks!
