O-Ring Replacement
O-rings are critical to the waterproof nature of the Apollo-X. The O-ring should be visually
inspected to make sure it is properly seated in the groove at the base of the threads and to
ensure there is no visible damage to the O-ring.
If the O-rings pass visual inspection and have been deployed for two months or less, they do
not need to be replaced.
If the O-rings fail visual inspection or have been deployed for longer than 2 months, they should
be replaced prior to re-deploying the Apollo-X.
To replace the O-Ring:
•
Remove the old O-ring with a non-metallic pick (toothpick), and clean all dirt away from
the threads and grooves where it was seated using a lint-free cloth, cleaning alcohol,
and a soft-brush.
•
Apply a thin layer of seal lubricant (
Molykote 111 from Dow Corning
) to the new O-ring.
•
Slide the new O-ring down over the threads of the endcap and into the O-ring groove.
It is very important to be aware of where the O-ring is sitting on the end-cap. If the O-ring is not
sitting perfectly in its groove, there will not be a perfect seal; this could cause fatal damage to
the unit.
