We are surrounded by several mechanical components which help ease our daily life. To keep these components efficiently running, maintenance plays an important role. Lubrication is the backbone of any maintenance activity related to the mechanical components. Heavy lubricants like grease are mainly used for vehicles, heavy-duty equipment, and other daily tools. To uniformly apply grease over equipment, a mini grease gun is used.
A mini grease gun is designed to manually apply grease over a surface. Pressure is created to help the grease flow in the tightest corners of the equipment. Since you will use this gun for regular maintenance, it must qualify for certain parameters. To understand the selection process of a mini grease gun, we must be aware of some governing factors.
- Extension Hose Length: The mini grease gun comes with certain hose types to apply grease over a surface. The main nozzle is always connected to a solid pipe to guide the grease over a surface. This pipe has a length of 3 to 6 inches. A flexible nylon hose is also connected to the grease gun if the surface is located in a complex spot. The length of this hose comes in a standard size of 12 inches.
- Working Pressure: Due to the thick nature of the grease, the working pressure becomes crucial for the grease gun. The mode of developing pressure varies depending on the model of the grease gun. Since the mini grease is a compact unit, a handle is used to feed pressure to the gun manually. The working pressure for these guns ranges between 2500 to 4500 PSI.
- Grease Capacity: Grease is the working fluid of the mini grease gun. The grease-holding capacity plays a major role in refilling the gun after usage. A larger capacity is always preferable since it eliminates the need to refine the gun constantly. These guns can hold 3 oz standard-size grease cartridges. Some guns are designed to hold 14 oz of grease at a given time.
As a consumer, you can prioritize these factors while browning through mini grease guns. The selection process for a mini grease gun also includes factors like the model’s specifications and features. We will discuss some of the best mini grease guns in this article to simplify your selection process. We have also included a “Buying Guide” and FAQ section to deal with confusion.

Buying Guide For The Best Mini Grease Gun
Greasing of components helps in reducing wear and tear of the surface under friction. With the mini grease guns, a user can apply grease in a controlled manner with a required amount of pressure. Since these guns are comfortable, we have already discussed a list of the best mini grease guns. With this buying guide, we will focus on certain governing parameters. This information will help you select a better grease gun.
1. Extension Hose Length
The mini grease guns have two types of pipe hose: rigid and flexible. Both hose types come in handy in specific situations to apply grease. The rigid hose is commonly found as a main component of the grease gun. It is made up of steel which can handle the high pressure of the loaded grease. The length of a rigid hose is usually kept between 3 to 6 inches due to a compact design. When users have to apply grease in a complex area, the flexible hose is used as an extension hose. Made up of braided steel wires and nylon, these hoes come in a standard 12-inch size.
2. Working Pressure
For any grease gun, the working pressure must be sufficient enough to apply grease uniformly. The pressure can be created via manual, pneumatic, and other options. The mini grease guns are equipped with a plunger and handle arrangement. When a grease cartridge is loaded in the gun cylinder, this plunger is extended to create room for the grease. Upon pressing the plunger, pressure ranging between 2500 to 4500 PSI is added to the cylinder. The mini grease gun also includes a bleeding hole to remove excess air.
3. Grease Capacity
The grease-holding capacity plays an integral role while using the mini grease gun. Depending on the grease in the gun, a user can operate longer before needing a refill. Apart from this, if the gun has a higher grease output per stroke, a larger capacity will help avoid frequent refills. Large capacity is desirable, but it can compromise the compact design of the mini grease gun. As a result, mini grease guns can hold from 3 oz to 14 oz of grease at a given time. This capacity range also matches the standard size of the grease cartridges.
4. Grease Coupler Type
Couplers are essential for a mini grease gun to connect its head with an extension hose. Depending on the desirable fitting and standard size, the coupler type varies. The most popular version of coupler is the hydraulic coupler, thanks to a simple connecting and disconnecting design. The threaded coupler offers a screwing mechanism to connect the extension hose. Magnetic hose use magnetic properties to secure the extension hose with a grease gun’s head. The 360-degree swiveling couplers allow rotation of the extension hose without disconnecting them with the head.
5. Warranty
Warranty is offered on almost every model of mini grease gun from every brand. These guns are equipped with several metallic parts which are susceptible to damage. Apart from this, a grease gun can also suffer damages in the form of manufacturing defects. Since a user cannot keep buying new grease guns every time damage occurs, warranty cover comes in handy. Warranty offers free raptors and even replacements of the damaged parts of the grease gun. The user must check the terms and conditions of the warranty scheme to avail of full benefits.
Mini Grease Gun – FAQs
Ans: To load a mini grease gun, users have to first extend the plunger rod to its extreme position. The next step involves unlocking the cylinder to access grease storage space. Users can load grease or a grease cartridge directly in this space. Users have to again lock the cylinder to perform the bleeding process. Retracting the plunger to its shortest position, the air is forced to move toward the bleeding hole. The gun is ready for use if the bleeding hole ejects only grease upon pressing it.
Ans: Comfort due to the profile of a pistol grip or lever grease gun is subjective for people. The pistol grip grease gun can be operated with the help of one hand. These guns are used for loading grease in high-tolerance areas. The lever grease gun requires power from both hands of the user. These guns are used to deliver higher pressure at lower efforts. Pistol grip guns deliver less grease compared to lever-operated guns.
Ans: The lubricant used in a grease gun must have good flowability to eject a controlled amount of grease. A dense or thick consistency keeps the lubricant stuck to the component’s surface. It must not react with oxygen or moisture under a specific environment. It should also show resistance to high temperatures to keep the components running in hot seasons.
Ans: Greasing of a component’s area has to be done in a controlled manner. When a sufficient amount of grease is not applied, the “under-greasing” situation arises. In this case, the moving parts of a component do not get a protective layer of grease, leading to higher wear on the surface. It also causes a rise in the temperature of the surface due to friction. When grease levels are beyond the specified limit, “over-greasing” happens. In this case, the seals may rupture, causing leakage.
Ans: Working as an attachment, the coupler helps in connecting extensions with the grease gun. It consists of a standard profile that matches the bridle on the extension hose. Couplers are important accessories as a user might need to change the length of the extension hose to access different areas of a component.
Conclusion
A mini grease gun is a must-have tool for regular maintenance activities. These compact guns offer a comfortable way to apply grease to complex areas of a component.
