MAINTENANCE OF THE MAIN GASKET SEAL
Each housing is individually inspected and hydrostatically tested in the factory. The design of the main
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 any 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 already installed, inspect and install the gasket according to the following guidelines.
GUIDELINES FOR INSPECTION, CLEANING AND RE-INSTILLATION OF THE GASKET
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.
