Loading a grease gun in bulk requires the use of a grease pump or ‘hydraulic unit’. The grease pump is a large container that is used to hold the grease before it is loaded into the grease gun. Once the pump is filled, the grease is then transferred into the grease gun.
To do this, the pump has a hose attached to it that is run up to the nozzle on the grease gun. The hose has a trigger mechanism that can be used to control the flow of grease into the gun. After the required amount of grease is in the gun, the trigger is released and the hose removed.
Another option is to use cartridges to load grease guns. These cartridges are pre-filled with grease and designed to fit directly into the gun. This makes it easier to load grease in bulk, as the cartridge simply needs to be popped into the gun and the appropriate amount of grease is loaded.
Overall, whether bulk loading a grease gun with a pump and hose or with cartridges, it is important to ensure that the grease gun is the appropriate size for the grease being used. It is also important to check that the grease gun is compatible with the pump and hose or cartridge being used.
Finally, it is best to follow the manufacturer’s instructions for loading and using the grease gun.
What size are grease gun cartridges?
Grease gun cartridges come in several different sizes, depending on the application. In the United States, the most common sizes are 14-ounce (400 g) and 35-ounce (1 kg) sizes, although smaller and larger sizes are available.
It is important to choose the right size cartridge for the specific application and type of grease being used. For industrial applications, 50-ounce (1.42 kg) and 135-ounce (3.86 kg) are typically used.
The heavy-duty construction and versatility of multiple-cartridge systems make them popular for applications that require a large volume of lubricant.
Which end of grease tube goes in first?
When it comes to the end of the grease tube that should be inserted first, the answer depends on the type of grease tube you are using. Most project-use grease tubes have an adapter that unscrews from the end of the tube.
In this case, the short end of the adapter should be inserted first into the gun. After that, you should screw the longer end of the adapter onto the end of the tube.
On the other hand, some grease tubes come with a plug, which means that no adapter is required. These tubes are generally easier to use because all you have to do is unscrew the plug and insert the tube into your gun.
Generally, the cap or plug will indicate which end should be inserted first by having a small rib or ridge on the inner side, which should be facing the gun when you insert the tube.
In summary, the end that should go in first on grease tubes depends on the type of tube being used. If the tube features an adapter, the shorter end should be inserted first. On tubes with a plug, the cap or plug should indicate which end should be inserted first.
Are all grease cartridges the same?
No, not all grease cartridges are the same. Different manufacturers offer different types of grease cartridges, each with its own unique formula and viscosity. In general, cartridges are used to store a range of lubricants and sealing compounds, including solid lubricants such as graphite, molybdenum disulfide, and metallic powders; semi-solid lubricants such as greases; and liquid compounds such as motor oils.
Cartridges also come in different shapes and sizes, including squeeze tubes, plunger-type canisters, and aerosol spray cans. Moreover, they can be designed to be refilled, or they may come in single-use, disposable containers.
As such, the type of grease cartridge you select should be based on your specific needs and the environment in which it will be used.
Are grease fittings universal?
No, grease fittings are not universal. While there are some general guidelines that apply to the standardization and size of grease fittings, there are also some differences between manufacturers and models.
This is especially true when it comes to industrial units and components, as they often use a heavier-gauge thread or fitting size. Additionally, there are also grease fittings of unique sizes that are specific to certain applications, so compatibility with a particular model or application must always be considered.
While using the wrong fitting type can lead to severe damage of the component, it is possible to purchase fittings with different thread sizes, such as Zerk and SAE, to increase flexibility.
Are there different types of grease fittings?
Yes, there are different types of grease fittings. The most common type of fitting is the standard fittings manufactured by Lincoln, SKF, and Alemite. These fittings come in various sizes and thread patterns to fit the needs of different applications.
Additionally, there are specialized fittings like the ones used in extreme-pressure and high-temperature applications. These fittings are designed to handle the additional amounts of pressure and heat present in those environments.
There is also the Zerk fitting, which has two ridges on either side of the tip instead of threads and requires special adapters for connection. This type of fitting is becoming more common as it is able to handle higher pressures than normal fittings.
Finally, there are stainless steel fittings with built-in seals that prevent any grease from escaping. These are often used in underwater applications as the seals prevent any water from leaking in.
Why is a grease fitting called a ZERK?
A grease fitting is called a ZERK because it is named after the inventor, a German-American engineer named William F. Zerk. He patented the device in 1929, which allowed mechanics to pump grease directly into a bearing or other wheeled part to keep them operating properly.
The fitting has a small hole for a lubricant to flow through, and is connected to a grease gun for convenient maintenance. It is thought that Zerk took part of the word ‘lubricant’ and combined it with his last name to coin the term ZERK, which has become the commonly used name for the fitting.
What is the thread size of a grease fitting?
The thread size of a grease fitting depends on the type of fitting. Standard grease fittings used in automotive applications typically have a thread size of ⅛”-27 National Pipe Thread (NPT). This is the same size thread used for many other applications, such as air lines, brake lines, and fuel lines.
Other sizes are available, such as ⅜”-28 NPT and ¼”-18 NPT, but these are not as commonly used in automotive applications. It is important to use the correct thread size to ensure that the fitting works properly and seals properly.
Also, make sure to use the correct thread sealant to ensure a leak-free connection.
How do I know my Zerk fitting size?
To determine what size Zerk fitting you need, you’ll need to measure the outer diameter of the male thread, or the inner diameter of the female thread. You can use a Vernier calliper to take this measurement, or if the thread type is consistent, you could use one of the charts provided by the National Pipe Threads (NPT) Standard to determine the size.
Once you have the diameter, you can then match it up to one of the Zerk fitting sizes in the chart. Keep in mind that the size designation for Zerk fittings generally refers to the nominal diameter of the threaded portion, and not the outer diameter of the nipple itself.
What is the difference between #1 and #2 grease?
#1 and #2 grease are lubricants that are used to provide a wide range of lubrication services in many industries, including automotive and agricultural. The primary difference between #1 and #2 grease lies in the base oil viscosity used, as well as the additive systems.
#1 grease will typically contain a higher viscosity base oil, and additives to improve the performance and resistance to wear, corrosion, oxidation, and water. #2 grease will usually contain a lower viscosity base oil and contain fewer additves or none at all.
The types of additives used can have a major influence on the performance and capabilities of each grease. Generally, #1 grease will excel in applications where heavy-duty services and higher temperatures are required.
#2 grease, on the other hand, is considered to be the most general purpose grease and is the most common type used. It is ideal for applications that may have light loads and temperatures that are not as extreme.
Why does my grease gun have no pressure?
First, it is important to check that the pressure hose is clear and not blocked. If the hose is blocked, or partially blocked, then the pressure may not be reaching the grease gun. The other common reason why your grease gun may not be reaching pressure is due to a lack of proper lubrication.
Grease guns need to be frequently oiled in order to keep up proper functioning and pressure. Additionally, the piston that typically pumps the grease out of the gun may be worn down and not pumping effectively.
Finally, if the valve for the grease gun is not properly seated, then it may not be providing enough air to create the necessary pressure. It is important to inspect all of these components to get your grease gun functioning up to par.
