Being a diver, either as a professional or for recreational purposes, requires bringing with you specialized lights for the purpose of clear vision under water. It is, however, very crucial that you take care of your dive lights, including regularly using lubricants on the O-rings of your lights. There are different lubricants suitable for different types of lights. Using the grease or oil assists you in protecting the O-ring from damage due to tearing, nicks, cuts, or pinching. It also assists you in assembling the parts faster and easier, making sure that it is done efficiently.

There are different types of lubricants on the market. People have been known to also improvise by using petroleum jelly when in a pinch, but silicone based lubricants are ideal for most dive lights. When choosing a lubricant, it is important to consider a few details so you purchase the most effective, efficient and texture-friendly product.

  • The lubricant should be able to withstand the temperature created by the dive light as well as the temperature of the water. This ensures that it won’t become too runny or too solid.
  • Choose a lubricant that will create a thin, long-lasting coating that stays on the O-ring. It is important to ensure this because the film acts as a protective layer that helps to prevent degradation and helps to improve the life of the o-ring.
  • It should maintain the size of the O-ring being used. Ensure that there is no resultant shrinking or swelling on the o-ring after application.

It is also important to ensure that you take care of your diving lights as a whole. Take care of the batteries, rinse your device with clean, fresh water immediately after use, or at least as soon as you can, and ensure that the O-ring is in its best condition prior to every dive.
