Magnetische stekkers

Magnetic plugs GN 738 attract iron particles which might be suspended in the liquid. To avoid breakage or de-magnetising, round rod magnets are fitted with a plastic distance and protection tube. This latter tube has to be removed prior to installing the plug. The sealing ring is retained in a radial undercut in the mating face which prevents it from dropping off and at the same time it cannot extrude under pressure.
