Typically grease guns will have three primary components: cylinder, propulsion control, and delivery device. The metal cylinder is the piece of the grease gun that contains the grease.
The propulsion control will generally be a level or trigger that the user utilizes to control the flow of grease. Most often the delivery device will be some form of flexible hose or rigid metal tube which will be equipped with a coupler. These products are most commonly trigger-operated, lever-operated, pneumatic, or battery operated.
The main advantage of a grease gun is the fact that the operator can insert the lubricant into a machine without causing any unwanted particles to contaminate the lubricants. Like wise this product is great for not causing any contamination of the lubricant itself in desirable locations.
Sometimes these items require specialized nozzles to properly function and it is important to note that often times over lubrication could possibly cause damage to the machine. Although grease guns are most commonly associated with a heavy type of grease these items can also be used to transfer lighter forms of lubricants.
Hand operated grease guns that do not utilize any form of trigger device will have the grease forced out through the grease fitting by means of back-pressure that builds up by pushing on the butt of the grease gun. Pneumatic grease guns will be equipped with an attachment for an air hose. Another type of grease gun that became very popular is the battery powered grease gun.
This style of grease gun is ideal for many applications where the user requires the product to be portable while still offering high performance. Battery powered grease guns are also preferred by some due to their cordless configuration of the product.
