MAINTENANCE OF THE MAIN GASKET SEAL
Each housing is individually inspected and hydrostatically tested in the factory. The design of the special
gasket seal is among the most reliable in the industry and the watertight integrity is excellent. This special
gasket design provides a perfect seal even if there is movement between the body and lid due to change of
ambient pressure.
With this in mind, the gasket seal is the only barrier between the water outside and the air space within the
flash. It is an effective barrier only if the seal is properly maintained. The gasket seal should be inspected
before every dive. The following information is provided for your guidance in using and maintaining the
gasket seal.
MAINTAINING THE GASKET SEAL
If the main body to lid gasket is not installed, install the gasket before diving. This is the only user
serviceable gasket. Its care and maintenance is critical to the watertight integrity of the housing. The gasket
should be replaced at the proper service interval (see Section on Service). If the gasket is contaminated, or
not yet installed, inspect and install the gasket according to the following guidelines.
GUIDELINES FOR INSPECTION, CLEANING AND RE-INSTALLATION OF THE GASKET SEAL
Materials Needed:
You will require a soft cotton cloth or Q-tip. Make sure these are free of all chemicals or contamination such
as loose fibers. You can moisten the cotton or cloth and wipe the surface of gasket clean—no silicon grease
or lubricant is necessary. It is advised to carry out the following procedure on a firm clean level surface, e.g.
at a table, to prevent skidding. This is especially useful if you are doing this maintenance from your diving
boat as it moves.
Maintenance of the O-Ring Seal:
Remove the gasket
periodically for inspection. It is not necessary to remove, clean and re-install the gasket
after every dive provided the gasket
did not become contaminated. The flash housing may be required to be
