SakerGrease Gun-Heavy Duty Pistol-Grip 7000 PSI Grease Gun Kit with 12" Spring Flex Hose,Nozzle Accessory,Fit for Oil Injection of Automobiles,Ships,Large Machinery and Industrial Equipment

After getting sick and tired of my four Lock 'n Lube couplers leaking and no one from Lock 'n Lube ever replying to my calls or emails, I decided to try Saker. I can say that, if you can get it clamped onto the zerks fitting, it will not leak...ever! That said, you better have really strong thumb/finger strength to operate these. I greased one of our GMC duallies yesterday. It normally takes an hour, two acts of god and a lot of swearing to get the two idler arms done. Manning up, or whatever you say nowadays, and squeezing the crap out of the coupler lever, I got it done in about 10 minutes. I highly recommend these, especially for easy to access fittings like on tractors, dozers, etc. I just bought three more to replace all my Lock 'n Lube couplers on all my grease guns.

Quality appears to be excellent. No leakage during disconnect.

Had no difficulty using this productWould recommend

Worked so well that it pushed some old grease through the axle on my riding mower. Super easy to attach in awkward spaces.

Works like it’s supposed to

Works like it should. Cool device

Fairly easy to engage and detach from zerks. Much easier than a standard coupler

I have several tractors, and a few are difficult to hold the gun on to the fittings. This device makes it so much easier to ensure the grease gets in. It can be difficult to open with arthritic hands, but is not too bad.
