How To Choose The Best Grease Gun

Let us mention five critical factors that you must keep in mind while you go on to buy a grease gun. These factors will help you choose the best grease gun from our list. You can also use it to select grease guns already in your mind but not on our list. These five factors are –

→ 1. Fittings

Generally, grease guns come with extra fittings. We have usually seen ball checks in grease gun heads. These balls help in preventing contaminants and dirt from entering the tool. This same piece helps in connecting the coupler to the grease gun. For meeting the specific needs, these fittings come in many different sizes. You can also choose the type of angle and bend you want. Hence look for the connections very carefully while you are looking and searching for a grease gun. If you are buying the gun for industrial applications, you must go with steel fittings as they are more long-lasting.

→ 2. Operation

The operation of a grease gun can be either manual or with the use of a battery. Compared to battery-operated grease guns, manual grease guns are slower and hence dispense grease at a prolonged rate. This slow speed is more comfortable to control and manage. On the other hand, the battery-operated grease guns require a lot of practice for lubrication. However, they are very helpful in reducing operator fatigue and are known to work very well when a large amount of greasing is required in the machine parts.

→ 3. Grease per stroke

Grease guns are well known to usually dispense at least one ounce of grease by more than 70 strokes. However, depending on the construction, this amount and number of strokes can vary. If you want high speed and a larger volume of grease to be dispensed, you must choose the lesser number of strokes required for each ounce of grease application. You can easily head on to the feature description of a particular grease gun to know details on this. But if you want a slower rate of grease application, you might look up for grease guns that require a high number of strokes for a per ounce of grease delivery.

→ 4. Grease Cylinder

The grease cylinder or container of the grease gun acts like a vessel when you wish to grease your machine parts. It is extremely important to know the capacity of this grease gun cylinder. It is generally mentioned in the description in terms of ounces. If you use the tool a lot in your garage, you might want to buy a grease gun with a cylinder with high capacity. Apart from this, one must also look for the ways by which this container or cylinder needs to be filled. In the market, some grease guns must be filled with cartridges; however, others only need manual filling. Additionally, there are grease guns that can be filled with grease using more than two methods. Hence, never forget to look up for that.

→ 5. Hose Length and Handle Grip

A length hose will allow you to reach the difficult-to-reach parts in a machine, engine, or motor. There can be many spaces where your hands cannot reach. In such situations, a long hose plays a very important role. These hoses can also bend according to the path so that they enter in depth. You must also look for a grease gun that comes with a grip sleeve on its handle. These sleeves are better known to offer better holding ability of the tool to the user. No one wishes to use a grease gun that cannot be handled well and keeps slipping. Look for these two factors very carefully in the grease gun of your choice.
