This is a great attachment for your Grease gun
Great product, I actually didn’t use it for grease but for injecting and epoxy into a basement wall crack, held the hose to the zerk without having to constantly push the end of the hose onto the zerk.
Having tried to grease my RV shackles the grease would not go into the fittings. This product fits the bill.
Used this on my tractor and zero turn mower. Makes greasing much easier. Clamp it on the fitting and you can use both hands to pump the grease gun.
This is an easy to use grease gun coupler. It locks onto the zerk fittings easily and firmly. The one problem I have experienced is that I have to switch to a different gun if the fitting is at an angle - because this thing is long and is best used for zerks that point into open space. Overall very pleased.
