M Series Port Hole O-ring
This O-ring is made out of NBR with a special hardness shore. It will perfectly secure the seal between the M ports series and the C2050 or C2060 main shell.
This O-ring is crafted to the precision tolerance required to hold a adequate seal between Liquid Eye M ports and C2050/C2060 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 M port may cause severe leak and void the warranty.
