This worked perfectly for greasing a IR 2317G! You ONLY HAVE to use this IF you have an impact wrench like the Ingersoll-Rand 2317G series that REQUIRE it. These types of models need to have the impact mechanism GREASED. Luckily, this model had a plug that this applicator fits perfectly into, instead of having to take the entire front casing off of. This grease IS the right weight of grease and was very easy to use. If left for a few days you did have to reprime the applicator, but that is not a hard thing to do. It was leaking a little after use, but then I started to squeeze less near the end of pumping grease into my wrench, and I don't have very much grease loss. It is good for preventative greasing on my other wrenches as well. It IS important to use an actual wrench grease of a proper weight for better maintenance and longer lifespan of the tool. This grease is also sold in 1 lb tubs if you don't need the applicator.
