## Description

Coupling Does your grease gun have difficulty greasing your equipment? Then you should buy a G coupling. Find out why: the annoying duty of greasing has already been revolutionised by the grease nipple. It was then the first design of Alemite, which adapted the grease nipple piece by piece. The first push-on couplings for grease guns. Over 80 years this system established itself despite some weaknesses: grease escapes from the grease gun and was wondered why so much grease dripped on the joints - the clutch dissolved under pressure, which forced you to hold the clutch during greasing - at back pressure the clutch locked and you could hardly manoeuvre it. were usually keeping keeping according according traditional a short service life, they were considered disposable goods. It's time to give this trend a new direction. The result? The G coupling. It is a game change, the patented grease gun coupling solves all the above problems, simple and elegant. Product Description Imagine greasing your machines would be easier. It would be less painful and less frustrating. This is what you get thanks to the G coupling for grease guns. With its patented sliding sleeves and the locking mechanism, the G-coupler provides flawless unlocking and a leak-proof seal. What does this mean to you? Waste and mess are a thing of the past. If your grease gun is under pressure, especially in deep pressure, then simply press the thumb lever and release the clutch. No more hassle for you and no more stuck couplings. This means that there are no more broken parts. For those of you who prefer lever presses: standard grease presses compatible: electric, pneumatic or hand-operated presses

## Questions & Answers

**Q: Does this work with Milwaukee grease guns?**
A: 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?**
A: 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?**
A: 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?**
A: It is just the fitting. The hose was included to give context and sense of scale.
