FAQs

How does a grease gun coupler work?

A grease gun coupler works by using a small hole in the top of the coupler and a grease gun to connect the two ends of the coupler.

Why does my grease gun get stuck on the fitting?

There could be a number of reasons why your grease gun gets stuck on the fitting. One possibility is that the fitting is not properly seated in the gun's barrel. If it isn't, the fit may not be tight enough, which can cause the gun to get stuck. Another potential reason is that the fit between the fitting and the gun is not good.

How do you adjust a grease gun coupler?

The grease gun coupler is adjustable to fit a variety of firearms. To adjust the coupler, loosen the screws on one side and move the coupler up or down until it fits snugly on the firearm.

How do you release a grease coupler?

To release a grease coupler, first remove the coupling from the engine. Then twist the coupling handle in a clockwise motion.

Can you over grease a grease fitting?

No, you cannot over grease a grease fitting. Grease fittings are designed to work with a certain amount of oil and grease. Over-greasing can cause the fitting to become tight and difficult to remove, which could lead to further damage or even failure.
