Have you ever had a camera housing flood? If so, chances are good that it was “user error”. That’s a nice way of saying that YOU are probably responsible in that you may not have maintained your o-ring properly. To save you future headaches and heartaches, we thought it was time to share the steps of o-ring care with you.

How to remove the o-ring with a credit card

First, open your housing and remove the o-ring. Sounds pretty simple, but the way you remove the o-ring can have consequences down the road. I recommend an o-ring removal tool (if your housing came with one) or a simple credit card (if you have an old department store card). Slide the corner of the tool or card under the o-ring and slide it over to a corner to remove the o-ring, stretching the o-ring the least amount possible. I know a lot of people who “pinch” the o-ring at the corner but that requires you to stretch it more to make the o-ring come out enough to get a grip on the slippery o-ring.

Next, clean the o-ring with a clean cloth. I don’t mean a paper towel but a clean cloth eg. a newly washed microfiber cloth or something that does not have any fibers or hairs on it. I use a product called Kimtech Kimwipes which is a lens kimwipescleaning tissue for cameras or laboratory optics. They come in a box like Kleenex and are very handy for the camera, lenses, housing glass and also the o-rings. They are also pure white so it is easy to tell when you are no longer getting dirt off the o-ring.

Note here: remember step #1. You don’t want to stretch the o-ring out as you work your way around the o-ring grove wiping it off, so try not to stretch it at all. I just try to slide it around against the cloth gently rolling the kimwipe so it is constantly getting a new clean surface as I move the o-ring around. Repeat until there is no more dirt on your cloth.

Clean the groove the o-ring sits in. You can use the kimtech wipes, microfiber cloth or q-tips fit very well into this groove. A word of caution on the q-tips: make sure you look over the groove at a 360 degrees for stray cotton fibers that the q-tips like to leave behind. Any fibers, hair or sand can be potential ways to make your fancy new camera a great paperweight. Be diligent and take your time!!!

Another tip I have learned along the way is to slide your q-tip or cloth around in one fluid motion. When I first started, I was going back and forth about two or three inches at a time working my way around the o-ring groove. This increases the possibility that gunk you have gathered up is going to be left behind at each backward swipe. Instead, start the q-tip at one spot and smoothly go all the way around the groove until you get back to your starting point. Swap ends of your q-tip or spot on the cloth and continue again and again until your cleaning tool comes out clean.

Now do the same process for the surface where the o-ring fits against on the inside part of the housing. Use one sweep around the entire surface and repeat until you come up clean. Look for any sand, hair or other particles that are in the area that could get lodged in the way and remove them.

Lube up your o-ring using a small amount of silicone. Make sure you use the type recommended by your housing manufacturer or there is a chance the silicone will not play nicely with your o-ring, resulting in a o-ring lubepaper weight! I place a small amount on my finger and dab about half of it on the o-ring and the other half on the opposite side of the o-ring. Slide your finger and thumb around the o-ring in both directions until it is evenly spread around. You are looking for a wet look to the o-ring, and you should not have any globs of silicone anywhere (if so, you used too much!). As you are sliding your fingers around the o-ring, use this opportunity to feel for any nicks or cuts in the o-ring. If you feel anything that is not absolutely smooth, swap to a new o-ring (It is good to have a spare one on hand).

Make sure the inside of your housing lens is clean and does not have any water drops on it before you replace the camera.

Replace your camera in the housing, making sure you have a new battery and an empty memory card installed. As you close up your housing do a last look around for hair, sand, fibers or even crumbs from your snack of choice. Make sure you remember to put in a desiccant pack or two to keep your camera from fogging. I have also heard of people placing dried and flattened sponges inside the housing with the thought the sponge could absorb a lot of water before it would get to the camera.

Many housings these days have a clear or see-through back. Use that to your advantage if you have one of those; otherwise, look at the side of the housing to watch the o-ring as you are slowly closing the door. Make sure the o-ring is seated in the groove properly as you close it up.

Power up your camera, take a picture and make sure your strobe set up or flash fires.

Dunk your camera, housing and strobes at home in a bucket of fresh water before you use the camera. Keep the lens generally pointed down as you submerge it (that way, if any water leaks in it will flow down to the lens port area where you are less likely to lose the camera). Watch for bubbles which is the tell tale sign of a leak. If you see any signs of a leak, take it out, dry it off immediately and determine the cause of the leak.

When you come home you can and soak your housing after your dive. Warm (not hot) water works best. Remember to push the buttons and work all the controls in the water and let them soak after working the buttons. Once you’ve rinsed it, remove the housing from the water and dry it off, paying close attention to the lens to make sure you don’t get any water spots!

As a PADI-certified diver, my interest in diving led to the opening in July 2008 of kirkscubagear, my online business. My site offers more than 2,000 products, including freediving, swimming and outdoor equipment. My continuing goal is to encourage diving and offer customers a shopping alternative for the purchase of scuba gear.
