LockNLube Grease Gun Coupler

This LockNLube Grease Gun Coupler is a total game changer. If you’ve ever struggled with traditional couplers popping off, leaking grease everywhere, or just being frustrating to use—this completely solves those problems. The locking mechanism is solid and holds tight on the Zerk fitting, even under pressure. No more grease spraying or wasting product. Once it’s locked in, it stays put, and releasing it is just as easy. Build quality feels very durable and well-made. You can tell it’s designed for real use, not just light-duty tasks. I’ve used it on multiple machines and it performs flawlessly every time. It also saves a lot of time and mess, which honestly makes the whole greasing process way less annoying. Highly recommend for anyone who uses a grease gun regularly—definitely worth the upgrade.

The LockNLube grease gun coupler is one of those tools you don’t realize you desperately needed until you use it. Absolute game changer. No more fighting with stubborn zerks, no more grease leaking everywhere, and no more hands covered in grease trying to hold the coupler on. This thing locks on tight and stays put. The build quality is outstanding — heavy-duty, solid, and clearly built to last. It grips fittings perfectly and releases easily when you’re done. I’ve used it on everything from tractors and trailers to lawn equipment and vehicles, and it works flawlessly every time. Honestly, it saves so much frustration and wasted grease that it paid for itself almost immediately. If you own greaseable equipment and are still using a standard coupler, stop wasting your time and upgrade. This is one of those rare tools that actually exceeds the hype.

This grease coupler works extremely well. It provides a very secure, tight hold on grease zerk fittings, which allows for better grease transfer and significantly less mess compared to standard couplers. The spring in the coupler feels strong and well-built, giving you confidence that it won’t pop off under pressure. It is slightly longer and a bit bulkier than the original couplers that come on most grease guns (both electric and manual), but that actually works in its favor. In tight spots where you can’t wiggle or twist the coupler to disconnect it, this one saves a lot of frustration. No more yanking on the hose or fighting to get it off the fitting. When I bought this coupler, I also picked up the LockNLube 8-Piece Quick Connect Greasing Accessory Kit, knowing clearance might be an issue in some areas—and I don’t regret that decision at all. The combination works great and makes greasing much easier overall. I’m very satisfied with this purchase and would absolutely recommend this grease coupler to anyone who does regular maintenance and wants a cleaner, easier experience.

Great addition to the toolbox, works great on ALL GREASE ZERKS, SAE AND METRIC

The threads are not the same that are on the Lincoln 1162 Pneumatic grease gun hose. I had to run an 1/8 NPT die on the grease guns hose threads to make it compatible. Other than that, it seems to work good.

Lock and lube grease couplers are awesome! Can’t say enough good things about them. Have one on every single grease gun I own and will continue to install them on any future grease guns i get. They are absolutely essential for a lever style manual grease gun! Still nice to have on a pistol grip, or an air or battery powered grease gun, especially if you use attachments like needle tips and right angle adapters! Do yourself a favor and try one, I guarantee you’ll never go back to a traditional grease coupler again.

Works as advertised. Eliminates problem with normal grease nozzle getting stuck on fitting. Great add on to make greasing easier.

This isn't a must have, but its worth having if you grease more than a lawnmower once a year. It does a decent job of staying on the grease fitting if you have to connect at a slight angle. its not perfect, if you have zerks with worn catches or more extreme angles it still leaks. The lever is a little bit difficult to depress but maybe I'm a wimp or my hands are the ideal dimensions. The only thing not to like about it is that often times on tractors/implements/loaders you have to reach the hose into a difficult spot and it won't fit - its annoying to have to switch couplers. In general lock n lube makes pretty good stuff. The packaging is good enough to keep components in place (compared to other companies that send stuff in organizers that turn into a jumble of crap in the shipping process)

Exactly as described. Very good product

Good shop ..and good product delivered on time

Great end, no spillage and gets a fine hold of the nipple, expensive but well worth the money.
