Buying Guide

Although grease guns are made basically the same way, there are still some differences between them. Being very useful devices with multiple applications, there are some things you need to consider before buying one to avoid making the wrong decision that can hurt you.

Types

There are three different types of grease guns, depending on the pressure delivery.

  • Manual: Traditional grease gun uses a hand level to pump the grease through the nozzle. Many of them feature a mechanism that prevents the grease from coming out until the user increases the pressure to the correct level. It is the least expensive and does not require an air hose or a power source, although it needs both hands to achieve high precision. On the other hand, pistol-grip grease guns are also manual guns that allow one-handed use.
  • Pneumatic: This type uses an air compressor to send pressurized air through an air pipe to push grease through the gun’s nozzle. What is more, the pressure produced by the air compressor may be difficult to control on smaller equipment.
  • Battery-powered: When using a rechargeable battery-powered grease gun to perform maintenance on a vehicle, boat, or lawnmower, the user can roam around freely. The batteries, on the other hand, must be recharged. Furthermore, grease guns are usually the most expensive alternative.
  • Electric: They automatically use the electrical power source to build up pressure for an application via an electric motor. These are also a very expensive option but can save you time and energy in situations when you need to do a lot of greasing.

Materials & Quality

The majority of products on the market are made of metal, which is a tough material that can endure the pressure created during use. Plastic components, prone to wear and fracture, may also be found in low-quality options.

As far as quality is concerned, the smoother the operation, the higher the quality. Working parts in high-quality grease guns make operating the product satisfactory. You will probably want one that is simple to use, distributes grease uniformly and accurately, and has a bleeder valve to remove air pockets.
