How to Replace the O Rings for Scuba

How to Replace the O Rings for Scuba
O-rings are an essential part of your scuba diving equipment. Without properly installed and maintained o-rings your equipment will leak, resulting in the premature depletion of your air supply. Properly maintained o-rings create a seal between one component and another. Over time o-rings will degrade and wear out due to use or neglect.

Instructions

Difficulty: Moderately Easy

Things You’ll Need:
  • Scuba tool kit Replacement o-rings Silicon based o-ring lube O-ring tools
  • Scuba tool kit
  • Replacement o-rings
  • Silicon based o-ring lube
  • O-ring tools
Step 1
Consult the documentation that came with your scuba equipment to identify the location of your o-rings, the size of o-rings and the quantity you will need. Also check to confirm that the type of silicon lube you have is compatible with your equipment.
Step 2
Lay out your scuba equipment and tools on a large flat surface. Disassemble your equipment as described in your owner's manual.
Step 3
Once the o-rings are exposed gently try to remove them with your finger nail first. If the o-ring is difficult to remove or parts of the o-ring stick, gently use a soft metal tool designed for use with o-rings to remove it or the debris. Do not use screwdrivers or other general purpose tools because these may damage your equipment and make it impossible to get a good seal.
Step 4
Select the proper replacement o-ring from your kit and apply a thin coat of silicon o-ring lube. Replace the o-ring and reassemble your equipment based on your owner's manual.
Step 5
After you connect your scuba gear to a full tank, listen for any unusual hissing sounds coming from your gear. When you first enter the water after replacing your o-rings, ask your dive buddy to check out your equipment and look for any leaks which might have occurred due to incorrect assembly or use of the wrong o-ring. A stream of bubbles from the seals should be noticeable. This should be done in as shallow of water as possible since the water pressure at deeper depths my temporarily seal a leak.

Tips & Warnings

 
If you cannot find the documentation for your exact size of o-rings, most dive supply shops carry kits which contain a wide variety of o-ring sizes.
