Information

Magnetic plugs GN 738.1 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 sealling ring is reatined in a radial undercut in the mating face which prevents it from dropping off and at the same time it cannot extrude under pressure.
