A car seal is a mechanical means of securing a valve in a certain operating position using a seal and a cable.  After a special locking key makes the seal, operation may be done only by means of cutting the cable.  Hence, it cannot be reused.  This is used for valves designated in the P&ID as “car-seal open” or “car-seal closed”.
