I find it to be best for machines not vehicles

I bought this item for my truck to lubricate all my fittings and it's not good for my trucks. Anyway, I took this product to work and it has worked great with the devices I repair and service.

Pros
  • Automotive
Cons
  • Could have chosen a newer model

Grease gets into the valve at a bottleneck.

The adapter must sit almost directly on the fitting or a leak will occur. I'll find an o-ring that fits the adapter and see if it helps seal the connection. But it looks like this is the only option if you can't get the end of a regular grease gun to the lubricator.

Pros
  • Fuel system
Cons
  • Obsolete model

Needs a better tip seal

I tried on a hard to reach mirror fitting and the tip leaked grease everywhere - nothing got into the fitting. Also leaked when using rubber washers. No force will stop the leak. The tip is just a steel indentation that doesn't really seal the tip of the mirror fitting.

Pros
  • Fittings
Cons
  • Hardly ever

Perfect for mounting Zerc to U-Joints

Since Zercs on my 3 U-Joints are straight there is no way to install a standard Zerc coupler between U-Joint grease fittings to fit them connect to Zerc. It's just too fat! This little "stab" is the perfect answer. I attached it directly to my grease gun with a 1/8" x 1/8" brass hex nipple (https://www.amazon.com/gp/product/B07CPZ9ZDC) to make it easier to get enough pressure on the Zerc to apply grease to the universal joints. Great product!

Pros
  • Replacement parts
Cons
  • Big and bulky
