GURTECH G.COUPLER - The Original Lock-On Zerk Fitting Grease Gun G Coupler, Easy On & Off (M10x1)

This is an excellent invention. My partner spends a many a long hour greasing machinery. But finds it very frustrating when the greasing pipe comes off all the time. He had never seen anyone using this before, so he bought it to see how well it worked. Well, it works fantastically. Greasing is now a quicker and simpler process. He no longer has to hold the greasing pipe on anymore. It stays in place until he pushes the button to release it. No more wasted grease, so saves money. It is quite expensive. But well worth the investment. It saves time, money and above all patience. Its the sort of invention for someone who greases machinery couldn't live without and wonder why it wasn't invented years ago. Its a simple but very effective thing that he will not be without until the day he retires. Don't know how long this will last as he hasn't long got it. But it seems durable

The Coupler is a fantastic grease lock on zerk i been using them for 4 years on my milwaukee battery grease gun i work in a HGV transport workshop and use every night put a minimum of 4 to 6 cartridges over my 5 night shift makes greasing so easy and if you get the repair kits the G coupler keeps on working the only reason i need the repair kit is after about 5 weeks does leak a bit only because the rubber o'ring gets damaged if you get a grease if you have a blocked grease nipple and pressurises and have to be rough trying to get it off the nipple but excellent grease zerk

This is an excellent grease fitting, it takes seconds to fit and performs flawlessly. It's been used daily to grease a mini digger and dumper. It takes the pain out of getting the grease coupler to fit. My only complaint would be that it is a little bit of a tight squeeze for a few of the grease points. Although this could be poor design from the excavator machine manufacturer, not really thinking about daily service routines.Excellent product will be ordering more.

Used to upgrade a dewalt battery powered grease gun as the supplied coupling was next to useless.The g coupler is excellent, however, its a little to long and is difficult to get onto the more awkwardly placed grease nipples.The 4 jaw mechanism locks into place over the grease nipples easily and when on straight delivers grease without leaking from the sides. The sprung handle also makes it easy to remove the coupler without having to twist or pull sideways on the coupler, reducing the risk of snapping the nipple off.

Bought this as the standard end that came on the grease gun I bought has caused me a world of issues . Used the original one once and it would not come of the grease nipple and I needed up breaking the grease nipple trying to get them apart.This part is amazing. Not had any issues. Really easy to use and is very well built.

It does what it says on the packet

Much easier to use than the basic one included with grease gun. No fear of breaking off a grease nipple with this.

I bought a grease gun off Amazon with the standard push-on coupler.Like others, I had difficulty removing the gun from the grease nipple.A quick Google advised me to bin the standard coupler and fit this quick-release coupler in its place.It makes greasing jobs so easy (I broke a nipple with the old coupler) and frustration free.Ok, it's not the cheapest device but it save hassle and broken nipples so is well worth it to me.
