O-ring Care & Maintenance
O-rings are the critical components that keep 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 rear plate 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 rear plate O-rings and the mating surface on the inside of the main
housing are free of 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 utilize two O-ring seals. Check these
seals every time the optic is removed.
