Must be a typo in Jeg's website; that's the stuff, the tube is identical to mine. It's made for their fasteners - head bolts, manifold bolts, etc. As I said, it's on nearly every fastener in mine where I want to 1) be able to reassemble, 2) seal against fluids, or 3) reduce the amount of torque needed to achieve the proper clamping force. If the threads are clean and you use this stuff to seal and lube, you can reduce a spec torque by about 10%.
