Does anyone know the size o-ring that the housing takes? Looking to buy them aftermarket from an o-ring store...
I would be super careful with any answer you may get on this.
Reason being that elongation and deflection of the o-ring under pressure is super critical for the groove recess and groove angle. This is further compounded with housing itself if made from polymers and plastics that by very nature are deformed and deflected by a change of temperature as well as pressure.

The second is that although the o-ring itself is easy to measure and will most probably comply to a specific country standard of size ID and cross section diameter. The polymer material itself and compound together with the shore hardness will be very different for a plastic camera housing than for say a metal housing.

If the value of the contents of the housing is important be it a camera or say battery housing my call would be to simply to buy the Original Equipment Manufacturers (OEM) component. I guess with one exception.
