The original post was about the IMS Guardian MCD sensor, not the LN Magnetic drain plug. The two units are not the same material, and are not even made in the same factory. They share nothing in common. They are also not offered by the same company.

A drain plug has no reason to be super tight, it is not a fastener; it only needs enough pre- load to crush the sealing washer and stay in place. The last poster stating that just beyond finger tight is ok, is something I agree with. This is why the MCD sensor torque is 19#.
