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
