J.W. Winco Aluminum Magnetic Threaded Plug w/ Viton Seal - M20 x 1.5 Thread (Discontinued)

J.w. Winco 738.1-26-m20x1.5 aluminum magnetic threaded plug w/ viton seal - m20 x 1.5 thread gn 738.1 magnetic threaded 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 groove 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. Maximum heat resistance: 200c
