GURTECHG.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

I've never got on with the standard 3/4 jaw grease gun nipple attachment. They always go on easy enough, grease spews out the end from around the nipple, then I have hell trying to get it off.I saw this and thought not cheap but from the pics it looked well made so gave it a go. Brilliant, it is well made and a doddle to use. Just push the lever and the jaws open, place over nipple and release lever which allows it to grip the nipple and seal the grease point of entry. Pump the grease gun handle and reverse attachment. So easy, no grease everywhere or struggling to get it off. Well worth it.

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.

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.

Works well.

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

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