o ring seal

If I adjust my head more than three times that little oring seal breaks. Can new ones be purchased or should just not use it?

Hi Ron,  Not sure what ring you are referring to.  There is a convex washer that seats against the screw and a rubber washer that holds the screw in the head.  You should not be seeing either washer as the both should be inside the head.  Please give us a call with your serial number and we can help.  1-888-TITLEIST
