Grease and adhesive guns are tools used for dispensing grease and adhesive materials with precision and control. These guns are commonly used in automotive and industrial applications for lubricating and sealing components. Grease guns are designed to apply lubricant to moving parts such as bearings, gears, and joints, while adhesive guns are used for dispensing adhesives and sealants. The guns are available in various types and sizes, including manual, pneumatic, and cordless models. They typically feature a trigger or plunger that controls the flow of material from the gun, as well as a reservoir for holding the grease or adhesive. Some models may also have a pressure relief valve to prevent over-pressurization and a pressure gauge to monitor the output pressure. Grease and adhesive guns are essential tools for maintaining equipment and machinery and ensuring proper operation.
