Ikelite O-Ring for Select Strobes and Housings

This Ikelite O-Ring is a replacement for the one included on the battery door of their DS-160 and DS-125 Substrobes, which run on the #4066.5 NiMH battery pack. It also replaces the O-rings that go on the front port mounts of their 200DLM and 200DLM/C Underwater Housings for the Sony Alpha a6500 and Canon EOS Rebel SL2 cameras, respectively. Resembling a thick rubber band, it is made of elastomeric material and designed to establish a watertight seal when going beneath the water's surface.
