Underwater Kinetics O-Ring for SL4 Xenon/eLED or UK300 Xenon Dive Light

Resembling a thick rubber band, this small but critical O-Ring seals your Underwater Kinetics SL4 Xenon, SL4 eLED, or UK300 Xenon light to keep it waterproof during your dive. The ring serves as a spare or replacement for the one supplied with your light.
