PROLUBE Quick Disconnect Grease Coupler | Hands Free Operation | No More Mess, Broken Jaws, or Broken Fittings | Works on All Types of Grease Fittings | 8,000 PSI | 1/8” NPT Threads #43546

Works well and makes it easier to grease the tractor.... only thing to note is it is bigger than I thought it would be and would not fit in one spot.

This thing is a big hunk of metal and an equally big disappointment. Some how this coupler is worse than the free coupler that comes with your grease gun. I've had the lock n lube before and I lost it, so I took a chance and bought this just to try something new. Worst mistake in my greasing life. It doesn't matter how much access you have or if the zerk is straight or at an angle, this thing will not couple and will not put grease into the fitting. Maybe if you pray enough it will work. Amazon needs to have zero stars as an option.

Very robust execution. It didn't seal on the fitting in my application. Grease leaked around fitting. Returned.

Easy to use, releases from the grease Zirk easy. A bit larger than most. Works well

A waste of money. Doesn't clamp onto fittings. Grease everywhere but where it's supposed to go.

Works on most fittings. They have to be in a open location.

Good product. Well made.

Basically worthless on any zerk that isn’t wide open. Thing is too big around to get anywhere. Lock N Lube is the better option.
