Butter Lip unclogging tool, available in both long and short versions, comes with M6 and M8 conversion adapters, is used to clear dry and clogged butter valves and restore the oil injection channels. It features a mechanical push-pull structure and can be reused. Suitable for auto repair and maintenance of construction machinery. For severely rusted or deformed butter valves, it is recommended to replace directly. When operating, avoid using brute force to turn.

This butter nozzle unclogging tool is a specialized equipment maintenance and repair tool designed to handle clogged and solidified butter nozzles. After long-term oiling of the equipment, the internal parts of the butter nozzle are prone to dry and harden, causing the butter gun to fail to inject oil properly. This tool does not require direct replacement of the butter nozzle; instead, it can complete the internal cleaning and Clearing and unblocking using this tool， suitable for maintenance operations of construction machinery， agricultural machinery， vehicle chassis， and various bearing and hinge points.

The tool comes in two specifications： long and short. It is equipped with M6 and M8 conversion connectors， compatible with most common specifications of butter nozzles available on the market. The main structure is a screw， and the operation relies on mechanical pushing. The dry and hardened oil inside the butter nozzle is pushed out by the screw， clearing the blocked passage and restoring the normal oil delivery capacity of the butter nozzle. The metal end of the push rod is equipped with a protective rubber cap. When not in use， it should be placed with the cap on to avoid damage to the push rod head from bumps. The overall construction is solid， with a moderate weight， making it easy for maintenance personnel to handle and carry with them on vehicles or in tool bags.

The operation is simple. Remove the clogged butter nozzle， connect the corresponding conversion connector according to the thread specification， tighten the unclogging tool， rotate the rear nut， and push the push rod into the interior of the butter nozzle to push out the dried and hardened old oil. After the Clearing and unblocking is completed， unscrew the screw， clean the oil residue， and then reinstall the butter nozzle into the equipment. Test the oil injection of the butter gun to check if it is smooth.

This tool can be used repeatedly， reducing the consumption of spare parts due to frequent replacement of butter nozzles. It is particularly effective for minor and moderate clogged butter nozzles. If the butter nozzle has already cracked， deformed， or suffered severe rust and damage internally，Clearing and unblocking cannot repair it. In such cases， it is recommended to directly replace the new part.

When using， take precautions for hand protection to avoid splashing of high-pressure oil and grease onto the skin. Do not forcefully twist the push rod when advancing it； prevent the push rod from bending and damaging. After the operation， wipe the surface of the tool of oil stains， put the rubber cap back on the end of the push rod， and store it properly to avoid deformation of the screw threads due to dropping or impact， affecting subsequent assembly and use. It is a practical maintenance accessory for machine repair， automotive repair， and agricultural machinery maintenance scenarios to handle butter nozzle clogging problems， improving the efficiency of equipment lubrication and maintenance.
