No seal a big deal.

Mechanics, far too many tank line replaceable units (LRU LRU - Least Recently Used ) are being put back into service after a repair job without new seals.

Using the old seal--or no seal at all--means moisture, dust and other contaminants get inside and damage the sensitive electronic components inside the LRU. Pretty soon, the LRU has to be repaired or replaced once again.

So make sure you discard the old seal and put a new one in its place. Then, remind tankers to keep high-pressure water and steam away from LRUs.

Penetrating Oil Penetrating oil or penetrating fluid is very low viscosity oil. It can be used to free rusted mechanical parts (such as nuts and bolts) so that they can be removed, because it can penetrate into the narrow space between the threads of two parts.

Got a part, nut, screw or hinge that's rusted in place? A few drops of penetrating oil will get it moving in no time. NSN NSN National Stock Number
