Sea & Sea O-Ring Set for YS-01 YS-02 YS-03 YS-D2 Strobes
The Sea & Sea O-ring Set for the Battery Cap of the YS-01, YS-02, YS-03, YS-90 Series, YS-110 Series, YS-D1, YS-D2, YS-27 and YS-30 Underwater Strobes is a must for the serious underwater photographer. The set includes all diver replaceable O-rings for the strobe. Sea and Sea recommend O-rings to be replaced annually, or when you are in doubt of their integrity.
O-rings are the most important components of your underwater camera system. If the O-ring is lubricated, it will be elastic enough to shape itself uniformly around the channel providing a proper seal. If it is dry, there will be too much friction to allow it to reshape itself uniformly.
Don't use a sharp or pointed object to remove an O-ring! We recommend that you use Sea & Sea's O-ring remover tool.
Don't over grease your O-ring. Too much grease attracts debris that will disrupt the seal and cause flooding. Silicone grease is not a sealant, it only protects the O-ring from abrasion. A perfectly greased O-ring looks moist and shiny. Be prepared and carry this convenient spare set wherever you shoot.
