Upon testing and evaluation, Dresser Masoneilan concluded that the internal O-ring used for pressure isolation in the Air Regulators were damaged during factory assembly contributing to the failure of the units to regulate pressure. Dresser Masoneilan has developed a corrective action plan and an in-service test method and acceptance criteria to determine if a unit is experiencing pressure loss due to the issue.
