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

Works well.

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

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

I had seen these on You Tube and finally got around to buying one thinking it might be worth a punt to soothe a daily job I hate, greasing my digger and tractor. I expected it to be a flop and thought I would have to shell out on an electric gun.Well, twist my nipple nuts and call me Sally, these things are simply brilliant!It clips over the nipple (grease zerks not yours) and the grease goes where it is meant to rather than oozing out. Once attached there is no need to hold it on, push it on, use both hands to make a seal and then pump with knees risking the family jewels. It just works and does not leave a greasy mess all over you nips!It releases very easily every time, it has never locked on due to pressure.Greasing up now takes a few pleasant minutes instead many many tedious sweary minutes. it really has taken all of the annoyance out of an essential daily task. My shed floor is no longer littered with blobs of dropped grease, I am no longer covered in blobs of dropped grease and the machines are looked after well.The G Coupler is well made, installs on to the gun in about 10 seconds with no fuss.One of the best £10 I have spent in a while, recommended!

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.

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

No more spills or messy grease points. Works well on those hard to reach or stuck grease nipple. Holds well and no messOnly wish I bought it sooner

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.
