This O-ring is attached to the anvil and backs up the tension ring. The O-ring minimizes how much the tension ring can compress when a socket is installed. O-rings are common wear parts that tend to harden and deteriorate over time due to their rubber material. A sign that this O-ring needs to be replaced is if the socket is no longer being held properly on the anvil. This manufacturer-approved part is sold individually.
