13 best pneumatic grease gun

A pneumatic grease gun is a tool used in automotive and industrial settings for lubricating machinery and equipment with grease.It is powered by compressed air, which allows for easier and more efficient dispensing of grease compared to manual grease guns. Here are some key points about pneumatic grease guns:

  1. Power Source: Pneumatic grease guns are powered by compressed air, which is typically supplied through an air compressor. This air pressure is used to force the grease from the gun's reservoir to the lubrication point.

  2. Efficiency: Pneumatic grease guns are known for their high efficiency. They can deliver a consistent and controlled flow of grease, making lubrication tasks faster and more precise. This is particularly beneficial in automotive and industrial applications where regular greasing is necessary.

  3. Continuous Operation: Unlike manual grease guns that require manual pumping, pneumatic grease guns can provide a continuous flow of grease as long as there is a supply of compressed air. This makes them suitable for heavy-duty and prolonged lubrication tasks.

  4. Pressure Regulation: Many pneumatic grease guns come with pressure regulation features, allowing users to adjust the amount of pressure applied when dispensing grease. This helps in controlling the flow rate and avoiding over-greasing.

  5. Variety of Nozzles: These guns often come with a variety of nozzles and attachments to suit different lubrication points and applications. This versatility makes them suitable for various tasks in the automotive and industrial sectors.

  6. Maintenance: Pneumatic grease guns require regular maintenance to ensure their proper functioning. This includes cleaning, lubricating, and checking for any wear and tear of components.

  7. Grease Compatibility: It's important to use the appropriate type of grease compatible with the equipment being lubricated. Different machinery and vehicles may require specific types of grease, and the pneumatic grease gun should be loaded accordingly.

  8. Safety: Users of pneumatic grease guns should follow safety precautions, including wearing appropriate personal protective equipment (PPE) such as gloves and safety glasses. They should also be cautious when working with compressed air to avoid injury.

  9. Applications: Pneumatic grease guns are commonly used in automotive repair shops, industrial manufacturing, construction, and agriculture for lubricating components such as bearings, joints, and fittings. Proper and regular lubrication helps extend the lifespan of machinery and equipment.

Overall, pneumatic grease guns are valuable tools in automotive and industrial settings where efficient and consistent lubrication is essential for equipment maintenance and performance. They are known for their reliability and ability to streamline the greasing process, saving time and effort for mechanics and technicians.

User questions & answers

Question: Can it be adjusted down? 6000 psi is too much pressure for most greasing applications I will use it for
Answer: Hi, this is a great tool except the air fitting. You must purchase an adapter to convert it to your fitting if the shop pro adapters are used. The pressure is NOT 6000 psi. Could be 60 psi instead. I am using shop air 110psi and it does push grease out quite bit far. You could ad a regulator in the line if you’re worried about pressure being too hi. You should be ok and please be aware this gun uses grease cartridge and they are working very well. Good luck
Question: I'm not able to lock the rod to the plunger and push the plunger into the canister - can't get the grease flowing. Anyone else have this problem
Answer: I didn't but sorry w/o seeing it I don't know.
Question: What size air fitting is needed? I use automotive style fittings, and all of my fittings are way too big to be threaded in at the bottom of the grip
Answer: I believe it is air fittings for 1/4 air hose
Question: Where is this made

User questions & answers

Question: It is just the fitting or does it include the flexible line
Answer: It is just the fitting. The hose was included to give context and sense of scale.
Question: After installing it, I couldn't depress the gun's pump. What did I do wrong
Answer: Between myself and friends we have successfully installed five of these fittings without any problems. As per the other reviews, I would first check your gun to see if was in fact pumping grease, then reinstall the coupler and try again, before you put it on a fitting. Could be that the fitting jerk that you tried it on was frozen. If it still does not allow grease to flow, it is defective and you will need to return it.
Question: Where is this product manufactured
Answer: Product of South Africa.
Question: Does this work with Milwaukee grease guns
Answer: The answer to this question is somewhat complicated. The standard LockNLube coupler has a 1/8" NPT hose connection. This will be compatible with all US grease guns EXCEPT SOME of the 18 volt Milwaukees. It appears that Milwaukee imported a batch of 18 volt guns that have 10x1 Metric thread on the coupler end of the hose - unlike the majority of Milwaukee 18 volt guns, which have the standard 1/8" NPT thread. There is no way to tell what the thread is without taking off the coupler and then test fitting a known 1/8" NPT onto the hose end to see if it works. If the known 1/8" NPT does not thread on, it is likely that you have one of the Milwaukees with the 10x1 Metric thread.There are indications that the most recent Milwaukee 18 volts are now coming through with the standard 1/8" NPT thread again, and not the 10x1 Metric.There are several solutions:1. Determine the thread type on your grease gun - chances are, there may be no problem at all with just using a standard 1/8" NPT thread LockNLube coupler.2. Replace the original hose with a new Milwaukee hose Part # Milwaukee 49-16-2647. The new replacement hoses are 1/8"NPT. The thread size is printed right on the front of the package. Your LockNLube coupler will then connect properly to the replacement hose.3. Contact LockNLube, by calling 603-795-2298. They now have couplers with Metric threads and will be more than happy to help work through this problem with you.Hope that helps!
