J.W. Winco Aluminum Magnetic Threaded Plug w/ NBR Seal - M26 x 1.5 Thread (Discontinued)

J.w. Winco 738-32-m26x1.5 aluminum magnetic threaded plug w/ nbr seal - m26 x 1.5 thread gn 738 magnetic plugs attract iron particles which might be suspended in the liquid. The magnetic pin is of a length which makes it impossible to demagnetize itself. To avoid breakage or de-magnetizing, round rod magnets are fitted with a plastic 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 out and from extruding when the plug is tightened. For this reason the seal can be of a softer material which offers better sealing. Nbr seal: maximum heat resistance: 120c (250f).
