In short, a grease gun is a tool used to apply grease to different types of machinery joints and bearings. Plunger rod handle : the plunger rod, or follower rod , is what puts pressure on the grease within the barrel. This is spring-loaded, and moves when the lever/trigger is pumped. The overall construction of a grease gun is largely the same, whichever model you choose. However, the design does change depending on the power type of the grease gun. In this section, we’ve highlighted the four main types of grease gun, and how these can be used. Pneumatic grease guns

Make sure all threading, couplers and connections are closed tightly but don’t over-tighten as this can cause failures in pressure and flow Push down or unscrew the air release valve. These are increasingly common, and are an easy way for air trapped between the grease gun head and filling to escape. They’re often used on larger machines that have several moving parts that need lubrication, where it can be difficult to apply grease under normal circumstances, like: Alternatively, angled grease nipples can make tighter or awkward gaps more accessible, which combined with a flexible extension hose means you should be able to attach the coupler of your grease gun firmly.Extension pipe : this extension pipe connects the coupler with the body of the grease gun, and can also be called a fixed tube .This design makes it easier for the grease gun to fit in small gaps and connect with hard-to-reach areas.

Handle/Pump lever : this provides the power for this type of grease gun. In this case, pushing the lever pumps the grease through the hose and out the coupler. Where it could be dangerous to have an external fitting, some grease nipples are designed to sit flush to the surface. These usually require a cone-shaped grease gun coupler, as they’re installed differently. These are the most efficient manual grease guns in terms of volume per stroke, which is ideal for when you need to move a larger supply of lubricant at once.

As you’ve seen in the diagram above, some grease guns use a side lever, which is raised and compressed to put pressure on the grease. Our excellent range of high-quality, but affordable, grease guns, grease nipples, and other accessories are perfect for applying lubricants to machinery and equipment whatever the job. Alternatively, you may wish to bulk load your grease gun directly from a larger store of grease. In this case, one option is to do the following. Always clean up any spillages immediately as grease left around on surfaces and floors can be a hazard Storing your grease gun horizontally helps to protect the plunger and spring from persistent stress and premature wear. This also means that if the grease does start to split, it does so evenly through the gun and is easier to fix by shaking the tool before use.

Clean your grease gun coupler and grease nipple thoroughly before use to prevent any contamination.For example, they’re commonly seen on suspension rigs where it’s otherwise impossible to manually apply lubricants to the internal systems. Whilst not highlighted, many grease guns come with an air release valve to help air escape before use. Output - The amount of grease delivered with each pump varies in different guns. Understanding the amount needed for each machine can help to ensure that you don't over or under grease machinery and cause damage to seals and motors. The amount of grease you need to use varies depending on the size of the joint you’re looking to lubricate, and how frequently you apply the grease.
