Your cart is empty. For more than a century, professionals have chosen the Lincoln brand for their lubrication equipment needs. We are dedicated to listening to our customers and their requirements. This dedication, combined with our understanding of the challenges of their daily work, led to the development of the problem-solving 5900 PowerLock Lever-Action Grease Coupler. Recognized as leading the industry, the combination of SKF and Lincoln lubrication technology continues to develop innovative solutions.
Designed for quick attachment to and release from the fitting during lubrication tasks, the PowerLock Grease Coupler allows users to use both hands when operating manual grease guns. The unique reverse-jaw design holds the grease fitting securely to the coupler's seat eliminating grease bypass. Its flexible rubber sleeve offsets pressure applied to the lever and protects the hose from unnecessary wear.
At every farm, construction site, automobile repair shop and industrial plant, maintenance professionals need high quality lubrication equipment and pumping products. Lincoln offers everything you need for lubrication. Our general-purpose tools and heavy-duty pumps, hose reels, meters and controls, used fluid systems and hand-held lubrication products are the best in the industry. LINCOLN – THE BRAND THE PROS DEMAND.

Put this coupler on a milwaukee grease gun for general farm use. It leaks so much grease in use that I threw it out before I got one tube of grease through it.

The unit locks on but just like a regular grease fitting gun you have to be right on or the grease will come out the side. The only difference is the unit will lock on which is nice.

1 star only because it came on time, I grease machines daily & hoped this Lincoln coupler would help having to change fittings all the time due to a Lil nick & grease slipping out & making a mess & not having to hold end on fitting constantly .its construction does look quality , BUT it wouldn't lock on very well & it made more of a mess than a reg coupler & its to large to fit in to any recessed fitting, I figured as it was Lincoln (big name in grease guns) it would be great , but it most certainly was not ! Complete waste of $. Donate your $ to a better cause as this was no good to me whatsoever , however I did purchase another coupler at same time , I had never heard of this company , but same product & purpose , Lock n Lube Is the company ,,, , it was cheaper & works 100 % , it clips on & stays on every single time ,& its smaller than a normal coupler & fits in recessed fittings no problem at all & doesn't make a mess ,,, To be fair I never contacted Lincoln about it leaking badly , I just took it off & keep it as a paperweight , but even if it didn't leak it wouldn't fit in any recessed fitting , it may look good in pics & it's does look like a quality piece ,but it's so big it's not gonna fit in anywhere tight , ujoints not a chance ,,, Don't waste your $ on this !,, buy a lock n lube grease coupler , it may not look as nice n fancy but it actually works & it'll fit in anywhere ,,& it was cheaper to boot ! Lincoln is a big name in grease guns n such ,, I couldn't be more disappointed in it !

Very disappointed in this coupler. Installed it on a Lincoln pneumatic gun, then tried to lubricate my tractor. It leaked grease on every fitting I tried it on. I ended up removing and replacing it with a competitors product which worked perfectly. Clearly a poorly designed product and I would not recommend that you purchase one..
