THINKWORK Grease Gun Coupler Set, Strong Lock on Greases Gun Couplers with 90° Grease Coupler Adaptor,12000 PSI Quick Release Grease Coupler Compatible with All Grease Guns 1/8" NPT Grease Gun Fitting

Absolutely a great product, works great, easy to use, no fuss no muss. Doesn't leak grease, fit my gun good.

It’s hard to get Quality grease Guns today. I have bought some that were cheaper that did not last very long and did Stay on causing leakage as you were trying to grease the bearings. These stay on so no leakage, are good quality and are easy to remove.

I didn't use it until 2 days ago and the window to return it has closed. The handle that latches to the grease fitting came off and I can't get it back on. Failed in only a short time. Poor design-useless......stay awayUpdate: product was replaced by seller-rating was improved

This coupler works great and makes greasing up my tractor a lot easier.

I grease a lot of heavy equipment, and had a lot of wasted grease. I bought this pecis of equipment for my grease gun, and no more wasted grease. It is so easy to use and fits all grease hurts. Just clip-on and away you go. Very good quality, great price easy to install on your grease line, can't go wrong. Makes a good seal on the zurk, no more wasted grease. With this tool I save about 8 to 10 Oz of grease on a tube of grease. That was a lot of wast, very little cleanup to do now. 2000 psi that great.

Works well and does what it's supposed to: locks on to zerks and doesn't leak. Cheaper than buying from the ship dock tool store too.

Was excited for this for the 90 fitting it works ok if you cut the spring off and get rid on the shield on it as far as the locking grease fitting it clamps good but came apart of first use and was a pain to get off got mad and threw it in the trash overall I will just get a lock and lube brand and try it

EDIT: I reached out to the vendor and they were quick to work on a suitable solution.I have used these ThinkWork heads in the past, and they worked as intended. The unit I received this time occasionally comes apart when you release the lever. I don't know if the hook from the coupler piece isn't bent enough or the trigger has more play. However, when this happens, you have to compress the parts manually, by hand or tool, to get the hook back over the trigger, to release it from the grease connector.

Bought this to try out since it was priced right. All I can say is Wow! does it ever work great, it’s small in diameter (I think slightly smaller than lock n lube) so there is no fuss when it comes to connecting to grease fittings. Not sure I can comment on durability just yet but for what I paid, I’m very happy. If it breaks later on I wouldn’t be mad, I’d probably buy another lol.

Works good and easy to install

Great kit. The nozzle grips well & the right angle adaptor is really useful. Small enough to get on recessed zirk on Kubota, Gehl & Dere pins.

Works amazing good quality bigger than it looks. I was so tired of snapping off zerks with the junk connector that comes on grease guns, this just turned my $30 grease gun into a $120 grease gun. The extension hose that comes with it is garbage but I already had a good one on the gun. Glad I bought this one and not the much more expensive name branded one. You know the one.

The connectors work really good. They grip the grease nipple and free up having to hold the grease gun on the grease nipple.The only downside is the hose. My rubber hose is much more flexible. Didn't use the one, stiff vinyl, that came with the kit.
