C2100 Back Plate O-ring
This o-ring is made out of NBR with a special hardness shore. It will perfectly secure the seal between the back plate and the C2100 main shell.
This o-ring is crafted to the precision tolerance required to hold a adequate seal on Liquid Eye C2100 water housing. NBR o-rings are easy to maintain.
It is important to keep them free of sand or dirt. You can slightly grease them once in a while. Marine grease is highly suggested for salted waters. Just put some marine grease on your fingers and slide the o-ring between your fingers to apply a thin coat of lubricant on the rubber. It is not recommended to over lubricate the o-ring. It may end up by sticking sand and other debris.
Please kindly note that using another type of O-ring to seal your C2100 back plate may cause severe leak and void the warranty.
