GN738.1 Threaded Blanking Plug, Magnetic, Aluminium
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 tube has to be removed prior to installing the plug.
The seal 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. For this reason the seal can be of a relatively soft material which will give better sealing.
Aluminium AL, fine turned
Magnet Alloy: AlNiCo, temperature resistant up to 180° C
Seal - synthetic rubber FPM (Viton), identification by not black finish of seal.
