Fantasea Spare O-Ring
for FG7X, FG7XII Housing
We always recommend ordering a spare o-ring for your housing.  If you're getting the Fantasea FG7X and FG7XII  housing, make sure to pick up an extra o-ring as well.
Note on Fantasea O-Rings:
The Fantasea G7X and G7X Mark II includes both a black and a white o-ring on the housing. Prior to each dive both o-rings should be visually inspected for damage, debris, hair, etc. Do not remove the white o-ring from the housing unless you see damage to the o-ring. The black o-ring should be carefully removed, cleaned and lubricated prior to your dives to ensure a good seal.
We recommend replacing the black o-ring every 200-300 dives or every 1-2 years depending on wear. The white o-ring will only ever need to be replaced if it shows visible signs of damage.
