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 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 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.

Note: 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.
