What is a Grease Gun Used For? Uses and Benefits of Grease Guns 2022

A grease gun is greasing equipment used for lubrication in workshops and carports. Via a specific aperture, it applies lubricant at a selected spot, typically from a grease cylinder to a grease fitting or ‘nipple.

While adding grease to the connectors of heavy machinery and dealing with the possibly messy work of loading a grease gun may appear to be a nuisance. Moreover, grease is the least expensive far wear part in whatever devices you’re using.

Types of Grease Gun

Various kinds of grease guns are used for various tasks. Another significant distinction between grease guns is the method of loading the grease: suction fill, cartridge, or bulk. There are the following types of grease guns:

Pneumatic(Pistol Grip)

This grease gun utilizes compressed air that goes directly into the gun via a hose, initiating a beneficial displacement with each trigger.

Manual(Pistol Grip)

This lever-type grease gun enables one-handed pumping, which is very usual. It delivers about 0.86 grams for each pump.

Battery(Pistol Grip)

It is a rechargeable battery, low-voltage grease gun that operates similarly to a pneumatic grease gun. It has the benefit of being cordless.

Grease Guns Are Activated In Three Ways

  • By hand
  • By air
  • By electricity

Uses of Grease Gun

Greasing attachments with a grease gun allows for greater accuracy, force, and flow control, allowing it to reach sides that otherwise is unreachable. Their most common application is on non-sealed fasteners that require constant lubricating grease top-ups.

Grease guns are commonly found in a wide range of industrial and do-it-yourself settings, with typical uses including:

  • Vehicle maintenance
  • Agricultural Equipment and machinery
  • Products handling machinery
  • Gardening and landscape design, especially chainsaw and lawnmower upkeep.

Steps To Load a Grease Gun

All grease guns drive on the same mechanism, but it is best to read instructions on the manual(manufacturer’s direction) before loading it.

  1. Pull the stopper back (a spring inside is packed(compressed) when you do this) and rest it on the device body’s grab.
  2. Take off the body from the head by unscrewing it.
  3. Remove any old grease tubes that may be in the gun. If the tube becomes stuck, slowly and deliberately release the plunger to force the tube out. Once your grip on the tube becomes tight, re-latch the plunger.
  4. Inspect that the plug that connects the device body to the actuator head hasn’t been laid to rest in grease and discarded with the old tube.
  5. Detach the plastic cap from the clean tube and add it into the device, accessible end toward the plunger.
  6. Take off the pop-top or foil. Be careful with this lid; it’s incredibly sharp.
  7. Reassembly of the tool is required.


To get any air out of a device that does not have a bleeder valve, the component must be primed or farted. Reassemble the unit and return it off one spin. Pull back on the plunger. It is important to move it down via the grease. Fasten the device and distribute the grease onto a piece of the card until it goes smoothly and without burps. If you apply pressure to the gripper and it does not resist, there is air in the device. Continue to pump until the circulation is no longer interrupted.

How to Use a Grease Gun?

Use the rag to clean the Zerk fitting before attaching the grease gun coupler; otherwise, contaminants will enter.

A Zerk contains both ball and check valve. The grease gun pushes the ball down, letting grease pass through. A spring presses the ball back into the opening when the tool is removed, encasing it. If the bearing does not come back and grease drips out, small particles may be impeding its efficient functioning, and you should replace the Zerk.

Pump grease sufficiently to hear escaping pressure and see a small amount of grease flow squeeze out of the arrangement under normal conditions. Essentially, you are using new grease.

However, don’t just continue to pump in grease. You can also ask your device dealer’s service center for advice on properly greasing the fittings. Wipe away any extra grease with a clean cloth.

If the wheels are immersed in water (as on boat trailers), installing a center greasing system such as Bearing Buddy is preferable, which simplifies upkeep.

Uses of Grease Gun- Frequently Asked Questions

How much pressure can a grease gun exert?

Grease guns can generate more than 15,000 psi for each stroke (shot), but most load-carrying lip seals can only withstand 500 psi. As a result, grease guns can create massive pressure and, if used incorrectly, can eventually crack out the seals built to stop bearings from outer pollutants.

What is the operation of a grease pump?

The pneumatic grease pump, powered by compressed air and has an auto rotary machine built into auto-repeat up and down, is a crucial piece of equipment for mechanizing oil or grease infusion devices. To force the amount of pressure and transport the oil or grease to serve the lubricating oil.

Wrapping Up- What a Grease Gun is used for

We hope that now you got enough information on what a grease gun is used for. Although it’s easy to use for everyone, however, to prevent injury, when greasing something with a draw point or that can drop, keep it in the lesser position or held in place with an approved strut.
