Does this work with any grease gun or just the Lock N Lube?

It should work with any grease gun whose output fitting is a standard zerk fitting. As shipped the adapter has a male zerk fitting for connection to a standard grease gun. We were concerned that when trying to remove the grease gun after greasing the adapter might detach from the grease gun but this proved not a problem for us. Presumably you could however remove the zerk fitting from the adapter and directly connect to the gun's grease pipe or hose. This proved a useful adapter for upper ball joints on the solid front axle of a 1989 V1500 Suburban. It would probably do U-joints as well.

Does this leak if it is at an angle?

Obviously this is designed to go straight on. That being said it will still seal at a small angle before it starts to leak. Maybe it will tolerate 10 or 15°.

Mine has silicone in it. Is that supposed to be in there?

The plastic inside the barrel of this adapter is supposed to be there to create the seal when attached to the grease fitting.

you can bet the knockoffs will show a pic "in-use" (for the 24/7/365 free sales increase). Why no pic engaged to a grease nipple?

Probably because when fitted, all you can see is the coupler - as the nipple would be completely concealed by it.
