Review on Push Slotted Degree Grease Coupler by Guerdon Draper

I really thought it was broken when I first used it because I couldn't get the lube out. However, remember to press it firmly over the Zerk fitting until it "clicks" and apply appropriate pressure from the hose fitting to this 90 adapter and it started working fine. Remember that it can be about you, so be prepared for this situation. I only have 3 hard to reach fittings. 1 on the old F100 and 2 on the quad so I have to use it minimally. I could see that something else is needed if you have a lot of customization where it might get boring, but it worked for my purpose.
