Q: Does this work with Milwaukee grease guns?

This does not work on the older Milwaukee m18 grease guns. They used a metric threaded hose on the older ones. The newer guns have standard thread and it will fit those. Take the current connector off the end of your grease gun hose. If the first 1/8 inch of the hose is not threaded, then you have a metric hose and this lock lune will not fit.

Q: Where is this product manufactured?

It is a quality product made in South Africa by Gurtech.

Q: After installing it, I couldn't depress the gun's pump. What did I do wrong?

Between myself and friends we have successfully installed five of these fittings without any problems. As per the other reviews, I would first check your gun to see if was in fact pumping grease, then reinstall the coupler and try again, before you put it on a fitting. Could be that the fitting jerk that you tried it on was frozen. If it still does not allow grease to flow, it is defective and you will need to return it.

Q: It is just the fitting or does it include the flexible line?

It is just the fitting. The hose was included to give context and sense of scale.
