This is another one of those things I wish I would have had a long time ago! I have a couple of other right angle adapters that I have tried over the years but they didn't work well for one reason or another. This one works well and gives you so many options for angles. What I didn't realize until I got it, is that it will lock into the straight position also, very nice! My side by side has a lot of grease fittings on it and they are all pointing at different directions or in tight spots, some of them I couldn't get without being able to go 90 degrees. This swivel coupler has made the job so much easier for me.

Great for hard to reach spots, the 90 Degree swivel helpsWorks as advertised, happy with it

Worked for tight spaces

This swivel coupler rescued my cheap, crappy, old grease gun and it became, well, still a cheap, crappy, old grease gun but one I can better use and keep for a good while longer. No leaks and it is a solid, well made piece.

Forget the quick attach add-on couplers. They leak and are hard to use. This replaces the whole shaft and coupler with a coupler that can swivel for 90 degrees or straight. Some reviewers don't realize that the coupler tightness is adjustable. You can twist the coupler body to loosen, put on zerk, tighten it, pump grease, then loosen it to easily take it off. This tool can be used with absolutely no leaking.I would like the shaft to be a few inches longer, but I am able to grease zerks which are in impossible placements.

Does everything that I purchased it for

Perfect

I Love this grease fitting!

Had one of these more than 30 years ago and lost it. Needed it recently for obstructed grease fitting and works great in my one-handed mini grease gun. Why would anyone need anything else???

It will make it easy to grease the center pully on my Lawn Boy mower deck. Looks well made.

This grease fittings tool, makes it easy to reach hard to get to , zooks.. it can be used straight or 90 angle. It is long enough, to keep your hands out of tight spaces. Also the end of this tool ,locks onto grease zook..tightly.

i used this design for lots of years my old one finally broke this is a must have for greasing equipment the new ones are made in china i hope they hold up as well as my old one-grease gun swivel extension!

Unit stick on Zerk and doesn't want to release well. In all other respects very very good.

Unfortunately, once the zerk is connected it is a real bear to get the grease fitting to disconnect. Especially so when it is in a tight space. Otherwise it works as advertised.

I have used it once and it got to a fitting that had been impossible to lubricate with a conventional rig. Happy I got it. Scraped my knuckles pulling it off. It does fit tight, once it is connected.

Bought to get to those hard to reach fittings. Works great!

I like this tool for the most part. I find it to be a useful addition to my small assortment of grease gun attachments because it allows me to reach some of the more awkwardly-placed grease fittings on my compact tractor and mower deck. Despite being made in China, I find it to be nicely built and it has a good, solid heft to it when held it in my hand. I like that the 180-degree swivel portion is slightly tight, yet still rotates smoothly, instead of being way too loose or floppy.One particular issue I have with it, though, is that the coupler portion, which actually connects to the grease fitting, is the cheaper 3-jaw type instead of the better and more robust 4-jaw type. While this doesn't necessarily detract from the overall usefulness of this tool, it does seem to reflect an attempt by the manufacturer to cut production costs where most consumers are unlikely to notice. To that end, I simply replaced this tool’s 3-jaw coupler with the LubriMatic 05-031 Standard Duty Grease Coupler that is exactly identical to the 3-jaw coupler except for it being a better 4-jaw coupler. In my opinion, this tool should have come standard with that 4-jaw coupler and it’s a bit irksome that I had to spend additional money to make that “upgrade” myself.All in all, however, I really like this tool and am glad I purchased it.One final pointer here for those who find themselves thinking that this tool must be defective because it won’t seem to release from a grease fitting. The coupler is SUPPOSED to stay on the grease fitting tightly whenever you pump grease into it. If the coupler gets stuck whenever you go to remove it from the grease fitting, it's because the coupler itself is screwed too tightly together on this tool to begin with. All grease gun end couplers have a threaded TWO-PIECE body that is supposed to be left a little loose so that the coupler can snap onto the grease fitting and then hold onto it tightly when pumping grease through it. If you find that you cannot release the coupler from the fitting, simply unscrew the two halves of the end coupler until you have relieved enough pressure on the 3 internal ramp ears (i.e., jaws) of this coupler to easily disconnect it from the grease fitting.

Never thought it would work so well. No leaks, fits zerk perfectly and releases quickly. For my uses it eliminates a flexible hose in most cases. As it flexes you would think it would leak around the joint but so far it is perfect. I would highly recommend for any manual operated gun.

Nice
