O-rings and maintenance

O-rings and maintenance essentials for underwater housings

O-rings are critical for watertight housings. Even a small scratch or grain of sand can cause leaks, so careful handling and proper maintenance are essential at all times.

Carrying a spare o-ring ensures reliability during travel or expeditions. Rubber ages over time, so seals need replacing after extended use or when visible wear is found. Not sure which o-ring or grease matches your housing? Please contact us via our contact page for tailored advice,

Correct grease and safe handling tools

Always use the correct grease supplied for your housing type. Using another lubricant may cause an o-ring to swell or lose sealing ability, reducing its effectiveness and safety.

• Brand-specific grease prevents swelling or damage
• O-ring wippers remove seals safely without scratches

Storing housings and seals after use

When not in use, housings should be stored with the o-ring removed or the housing left slightly open. O-rings last longer when stored in a dark, dry place with the right lubricant applied.

For further instructions, see our maintenance guide for underwater camera gear, which explains cleaning, lubrication, and long-term storage in more detail.

Practical advice for divers and underwater photographers

Preventive maintenance reduces the risk of flooding. Always apply the correct grease before each dive and inspect o-rings for particles or scratches during preparation.

Using proper tools and spare seals ensures that housings remain safe and reliable, even on extended dive trips or in remote locations.

• Spare o-rings keep housings watertight
• Use only the correct grease for each model
• O-ring wippers remove seals safely
• Proper storage extends seal lifespan
