Plugs and sensors (a) Screw-in plugs (4) are sealed toward the outside either with a copper sealing ring (1), according to DIN, or an O-ring (ISO). In case of a loose thread or a defective sealing ring (1), the liquid first has to pass the thread. The pressure is so greatly reduced by this and the faulty sealing ring (1) that any leakage is not under pressure.
