4.5 Maintaining the O-ring Seal:  

 

If the main body to lid O-ring is not installed, install the O-ring before diving. This is 

the only user serviceable O-ring.    Its care and maintenance  are critical to the watertight 
integrity of the housing. The O-ring should be replaced at the service interval (see section on 

service). If the O-ring is contaminated, or not already installed, inspect, grease and install the 

O-ring according to the following guidelines. 

 

 
4.6 Inspection, cleaning and re-instillation of the O-ring 
 

Tools:  
 

A soft cotton bud or sponge applicator, make sure these are free of all chemicals or 

contamination such as loose fibers, and the tube of silicone grease supplied with the housing 
are required. Note other types of silicone grease specifically for use with underwater camera 
equipment can usually also be used. It is advised to carry out the following procedure on a 
firm clean level surface, (e.g. at a table), to prevent skidding especially useful to have when 

diving from a boat. 

 

 

 

When to maintain the O-ring seal:  
 

Remove the O-ring periodically for inspection. It is not necessary to remove, clean and 

re-install the O-ring after every dive provided the O-ring did not become contaminated. As a 
rule of thumb set up the camera and housing before a day’s diving. If the housing is required 
to be opened between dives for changing memory card or re-charging batteries, make sure 
the outside of the housing is thoroughly toweled dry before opening up.  After removing the 

lid and servicing the camera, replace the lid straight away, rather than leaving it lying around. 
Before replacing the lid, make sure that no contamination such as dust, hair, salt, sand etc. 
has fallen onto the O-ring or O-ring recess, as a precaution we recommend to inspect the O-

ring every time the lid is opened and to carry out the maintenance if necessary.  

 

Procedure: 

 

 

Place the lid on a firm non-slip level surface.   

 

The O-ring can be extracted using an O-ring extractor tool (make sure the tool has no 
sharp edges).  Alternatively use the flats of the thumbs to gently stretch the O-ring on 
two faces (Fig. 4) thus making a small loop protruding a few mm. The loop can then 

be grasped between finger and thumb, to pull the O-ring over the lip. 

 

Clean the O-ring recess (the square groove where the O-ring sits) with a cotton bud or 
sponge applicator. 

 

Inspect the O-ring all the way round its surface for damage such as cuts tears or 

contamination. This should be done visually and also by feeling the surface texture 
between finger and thumb.
