O-ring Care & Maintenance
O-rings are the critical component that keeps water out of the housing. Routinely
inspect O-rings and replace at least once a year. If your O-rings are damaged,
contact the Light & Motion service department for an O-ring replacement kit.
Follow these steps for proper O-ring function:
1. The sealing system used on the monitor back incorporates two O-rings.
This is the most critical area of the housing for maintenance and should be
inspected before every dive.
2. Make sure the monitor back O-rings and the mating surface on the inside
of the main housing are clean from grit, hair, lint and anything that could
potentially breach the O-ring seal.
3. After frequent diving or if O-rings appear dirty, remove O-rings and clean
the grooves. To remove O-rings, use finger pressure or the rounded edge
of a plastic card to lift the O-ring out of the groove.
Never use a metal object to remove an O-ring. It will cause damage
to the O-ring and mating surface.
4. To check O-rings for damage, place the O-ring between the index finger and
thumb. Then pull the O-ring through your fingers, feeling for any debris or
wear.
5. If O-rings are dirty, it is best to replace them. Washing dirty O-rings with
soap and water is not recommended. Soap breaks down the lubricants and
will compromise the integrity of the seal.
6. Properly greased O-rings will help maintain sealing integrity and minimize
O-ring degradation. Use enough grease to lubricate the O-ring thoroughly,
but not so much that it will attract additional debris.
7. Clean the groove with a lint-free swab or the folded edge of a paper towel.
8. All of the front optic ports for the housing also utilize two O-ring seals. Also
check these seals every time the optic is removed.
