How to Attach Grease Gun to Zerk Fitting Quick And Easy

Attaching a grease gun to a zerk fitting is comparably a tricky part where most people lost track because of the lack of proper knowledge. But today I’m going to teach you some easy steps on how to attach grease gun to zerk fitting. Follow my steps and you will get the job done in no time.

 

How It Works

The working principle of a zerk fitting is very simple. The zerk fitting is a small nipple, containing a ball bearing and it threads into a hole. This keeps the contamination out from the gun and keeps the grease in.

The way it is designed, it allows the grease gun to push clean and fresh grease into the fitting. Whenever a greasing requirement is found, a hard to reach point is found, where lubrication is needed. In this case, zerk fittings are there to help you.

How to Attach Grease Gun to Zerk Fitting

  • First what you need to do is set the grease gun right. Meaning, fit the extension hose with coupler on the tip of it to the grease gun.
  • You’ll see a 4 jaw construction inside the coupler. It is basically a 4 jaw construction type.
  • This 4 jaw construction can change its position manually. They are spread out at first and you’ll notice some space between the jaws.
  • When you turn the coupler to screw it, you’ll see the 4 jaw construction closing up.
  • Now, you already know that zerk fitting is a small nipple containing a ball bearing and it threads into a hole. The hole here indicate 4 jaw construction in the coupler.
  • You’ll have to put in the zerk fitting inside the coupler.
  • Now, turn the coupler so that it pinches down the jaw construction to hold the zerk fitting by its shoulder. The shoulder is the part that is under the ball bearing part of the zerk fitting.
  • Once the 4 jaw coupler is clamped down on the fitting, you are hands-free and you are good to go.
  • Remember, you have to screw the zerk fitting tight with the grease gun. Otherwise, the zerk fitting will pop out from the grease gun. This is a very common case with the grease fitting in the grease gun.
