XTAR Dive Light

To extend the life of xtar D30 4000 dive light, a very important action is to clean the waterproof O-ring and add lubricating oil after diving. Check this video below to get more details.

Firstly, to remove the O-ring safely. Wipe all dirt and grease from the ring using a soft and clean cloth. Inspect the o-ring for cuts, nicks and any signs of wear. Replace the O-ring if its worn or damaged. To lubricate the o-ring, make sure it’s greased enough but not too greasy either. An O-ring which has been lubricated properly is smooth and slick with grease. This let it properly slide into the groove on the dive light and create a nice, tight seal.
