How to Buy the Best Grease Gun for Money

Why Use a Grease Gun?

The main purpose of a grease gun is to lubricate any moving part of a machine for reducing friction and inducing smooth action. Grease guns are applied for a variety of functions ranging from DIY to commercial.

  • Automotive Vehicles:

Lubricating guns are used for the grease fittings of lightweight trucks, heavy-weight trucks, and large commercial trucks. The grease fitting includes drive shafts, various U joints, etc. The sport utility vehicles also require lubricating on a regular basis. Marinating a proper Lubrication routine not only assists the vehicles to run smoothly but also keep their fittings sound for many years.

  • Agriculture Equipment:

Some agricultural types of machinery and equipment have moving parts which need regular greasing for smooth operation and longevity without frequent maintenance.  Grease guns are required in the agricultural machinery like tractors, vacuum pumps, lawn mowers, bailers, compressors, etc.

Battery powered cordless grease guns are widely used for lubricating agricultural equipment. Nowadays, you would find a range of lubricating guns specially made for agricultural purpose.

  • Lawn Mowers:

Grease guns are also handy for lawn mowers. You might experience trouble in lubricating the fittings placed on the back-side of your lawn mower’s spindle. A lubricating gun can make this task easier. It can lubricate the hard-to-reach places like axle pivot of the grease fitting. Besides this, the pedal bottom of your lawn mower also requires proper greasing for efficient operation.

  • Chain Saw

Chainsaws have bar nose sprockets, which need lubrication. A chainsaw saw specific grease gun comes with a piercing end which can efficiently lubricate the saw’s bar nose bearings. Proper greasing makes this tool operate smoothly.

  • Industrial Machineries & Factory Equipment

Diverse factory equipment and industrial types of machinery require greasing in their regular maintenance routine. The advanced types of machinery feature ball-check mechanism for preventing internal jams by the darts/debris. A lubricating gun can easily reach those remote places for routine greasing operation. However, you need proper technical knowledge for handling the gun’s high pressure during the greasing operation.

Types of Grease Gun

  • Pistol Grip Grease Gun:

Did you play with a toy pistol in those childhood days? If yes, then you would love the pistol grip operated grease gun. Like a pistol, this trigger operated lubricating gun can be operated through one hand only. If you prefer a small lubricating gun with convenient use, pick a pistol grease gun operated by the trigger mechanism.

It is the best grease gun for DIY projects. While pushing the trigger, you can opt among various speed levels depending on your lubricating-need. These pistol grip guns are widely used by people for their simple and effortless operation.

  • Lever Action Grease Gun

The lever-operated lubricating gun is one of the most available and highly popular grease guns. It triggers grease through a lever operated by two hands at a time. All you need to do is pull the lever with two-hands to create enough pressure for pushing out the grease from this lubricating gun. For cautions against mess, make sure the nozzles and hoses are connected and placed properly.

The length and speed of stroke would control the amount of grease dispensed by the gun. A slow stroke would generate lesser pressure and a smaller rate of flow comparing with a faster stroke. However, using a lever-action lubricating gun for a long period can be inconvenient and tiresome. Lever operated grease guns are less suitable for professionals. It is best for homeowners, who would use this tool not very often.

  • Cordless Grease Gun

If you are looking for a lightweight and portable lubricating gun, go for a cordless grease gun. The cordless grease guns are operated by rechargeable battery-power, so you can easily escape the limitation and/or nuisance of supplying power through hose/cord. It features a low-voltage operation with consistent pressure. Using a cordless grease gun you can apply grease easily without tiring your hands.

Though a battery-powered grease gun may offer fewer features compared with the other type lubricating guns, it offers you the freedom of movement. You can carry this cordless tool while moving in different workplace. In simple words, a battery grease gun is best for outdoor use, where no electric port is available. However, don’t forget to charge the batteries properly, before applying a cordless grease gun; otherwise, it might get shut-off in the middle of work.

  • Manual/Hand Pump Grease Gun

Compared with other type lubricating guns, a hand pump action grease gun is less popular among the consumers for it’s complex mechanism. However, if you are a pro, then a hand pump operated grease gun can give you the desired output.

A handheld grease gun is equipped with a pump attached to it’s upper section. Usually, this pump is portable and small in size. When you operate this pump, the air enters the gun’s cylinder and creates considerable pressure over the interior ambient. Then, the gun can dispense out grease.

Hand pump grease guns are not only powerful but also versatile. They can deliver grease more accurately comparing to other type lubricating guns. That is why handheld grease guns are best for professional applications.  They are also great for DIY projects if applied with proper technical knowledge.

  • Air Powered Grease Gun

If you are looking for a lubricating tool for commercial use, check out the air powered grease guns. Unlike the aforementioned – pistol, cordless, manual or lever – lubricating guns, an air grease gun is inappropriate for domestic use. Rather, it is highly potent for industrial applications.

To dispel grease, you need to connect the air operated grease gun with an air compressor through a cord/hose. As the compressor can supply a huge amount of pressure, the air grease gun can deliver a huge amount of lubrication required for the heavy-duty machinery in the factories.

However, operating an air powered grease gun requires accurate knowledge and right precautions; otherwise, it can damage the seals and bearing shields or even can wind the electric motor. The air grease guns are quite noisy, which can disturb the neighboring areas. As an air lubricating gun is extremely powerful, it comes with a higher price tag.

What Factors to Consider Before You Buy a Grease Gun?

  • Greasing Purpose

Grease guns are used for lubricating the moving parts of vehicles, trucks, lawn mowers, tractors, chain saws, compressors, etc. Not all type of equipment require the same level of pressure while greasing. Another question is how frequently would you use the grease gun? Depending on the specific purpose and workload, the type and feature of grease guns vary.

The portable grease guns are suitable for machines used in outdoor activities. Low-tier or medium tier hand operated lubricating guns would work fine for DIY projects. While air powered heavy-duty grease guns are appropriate for professional and commercial applications. So, pick the right grease gun which complies with your precise need.

  • Power Source

Lubricating guns vary depending on their source of power, like battery powered, hand operated, and air powered. If you want a grease gun for rare use in DIY projects or home improvements tasks, then a hand powered lubricated gun would be fine.

But, in the industries and factories, high-powered air grease guns are required for lubricating the grease fitting of heavy-duty machinery. Battery powered guns are handy when you need to move freely from one place to another for lubricating tools and machinery. Besides the commercial use, the air-powered grease guns are also suitable for professional use.

  • Pressure PSI

The grease guns featuring high pressure can create a high rate of flow for lubricating a larger area in less time. While their low-pressure grease gun counterparts are capable of dispelling grease more accurately on a specific area.

If you are looking for a grease gun for lubricating household equipment like, washing machine, dishwasher, small tractor, lawn mower, etc., then you can pick a grease gun operating at 5000 PSI air pressure. For commercial use, the level of pressure of a lubricating gun should be at least 10,000 PSI. However, if you need to apply to grease for versatile projects, then choose a lubricating gun featuring pressure variety.

  • Accuracy

While lubricating the greasing fitting of a household machine, you can be a little bit flexible in the matter of accuracy. But for professional projects and commercial use, pinpoint the level of accuracy is expected to run the machine efficiently.

So, it is wise to pick grease guns that offer attached hose for lubricating hard-to-reach spaces. What is more? Grease guns featuring narrow stream can perform better for greased on the exact target location.

  • Safety

When grease guns are built in the United States, European countries, and Canada, they go through a tough safety certification process during their manufacturing stages.  Some standard lubricating guns offer safety lock feature which can save your kids from dispelling lubrication from a grease gun accidentally. Before buying any grease gun, make sure it complies with proper safety standards.

  • Fittings

While buying a grease gun compatible with your need, it is essential to check the fittings. And, grease gun fitting can be divided into four types.

  1. Standard Hydraulic: This type of fitting is widely used in air grease guns. It is suitable for convenient operations.
  2. Pressure Relief Vent: This type of fitting can prevent the mechanism from creating too much pressure inside the gun cylinder. It can prevent the seal for untimely damages.
  3. Button Headed: It can dispel a considerable amount of lubrication. This type of fitting can grease the connectors properly.
  4. Flush Type: It is the smallest one. This kind of fitting is perfect for lubricating compact equipment or any machine which is spaced on a limited space.
  • Couplers/Adapters

There are mainly four types of adapters.

  1. Standard Hydraulic: This type of adapter is very common and highly preferable for standard operations.
  2. Three Jaw Swivel: It is the most versatile kind of adapter, which suits well with a range of fittings. It can be adaptable as per need.
  3. 90-degree or L-shaped: This adapter’s L-shape makes it appropriate for restricted sections.
  4. Needle-End: This type of adapter features a thin and long shape, which can be applied for reaching a narrow space.
  • Accessories:

1. Grease Meter

It is essential to apply the right amount of grease for lubricating a bearing properly. Inappropriate greasing leaves the risk of not only wrecking the bear but also damaging the whole equipment. To escape such catastrophes, buy a grease gun which comes with a grease meter gauge.

The grease meter would accurately measure the dispensed quantity of grease. And, you can see the reading on the display. The standard grease guns feature digital grease meters offering several unit conversions.

2. Dust Proof Plastic Caps

The effect of dust and debris can hamper the contact resistance leading towards the corrosive effect. When your gun is covered with a dustproof plastic cap, it can prevent the dust attack.

3. Needle Like Grease Injectors

When your grease gun comes with a needle-like grease injector, it offers an added bonus for lubricating the hard-to-reach areas. A standard needle injector gets a nice fit with any hand action grease gun. Usually, a needle injector comes with a plastic sleeve for safety reason.

  • Ease of Use

Who wanna buy a complicated tool? While buying a grease gun, don’t forget to check it’s usability; otherwise, it might cost you time and effort. Smart design details can contribute to making a grease gun more user-friendly.

For instance, standard grease guns come with LED light which helps the user in performing the lubrication task in the low light situations. Furthermore, some models feature extended hose which facilitates the gun in reaching remote places. Some grease guns feature an anti-slippery rubberized sleeve along their barrel. These clever design additions make the grease guns more user-friendly.

  • Hose Type: Fix of Flex

1.Fix Hose:

This type of hose is perfect when you are using both hands for operating the lubricating gun. So, fixed tube/hose is required in the lever action grease guns as well as pump operated grease guns.

2. Flex Hose:

It works great, while you are using one hand for holding the tube/hose in the right position and the other hand for operating trigger. Flex tubes are compatible with the pistol operated grease guns, battery-powered cordless grease guns, and air powered grease guns. It is perfect for dispelling grease on the remote spots.

  • Cartridge Capacity

Not each grease gun features the same level of cartridge capacity. You need to pick the right lubricating gun offering adequate cartridge capacity considering your specific greasing purpose.

For instance, when you wanna lubricate the grease fitting of a lawn mower or dishwasher, a grease gun featuring 3-ounce cartridge capacity would be fine.  For commercial use, get grease guns that offer at least 14 ounces of cartridge capacity.

  • Amount of Lubrication Output per Stroke

Both over-greasing and under-greasing situations could harm the grease fitting of machinery or vehicle. So, pick a grease gun which can deliver the right amount of lubrication per standard number of strokes. Lubrication output per stroke indicator of a grease gun is calculated by calibrating the average output level of ten continuous strokes.

However, the amount of lubrication per stoke differs from one-type grease gun model to another depending on their mechanism. But in general, the level of output per stroke ranges within 0.5 gram to 3 grams. So, choose the right model of grease gun which can deliver your desired amount of lubrication per stroke.

  • Loading Method

If you are ready to buy a massive volume of grease, then you can load a grease gun through suction loading. In this method, you need to create organic pressure for leading oil in the lubricating gun. Buying bulk grease is cost-effective. However, the suction process can create a messy situation, if not handled carefully. An inconvenient oil loading process can be irritating, as you have to face this issue every time, whenever you attempt to load oil.

If you prefer a cleaner and easier method for loading oil, go for cartridge loading. This method has no risk of mixing new grease with the leftover of old grease. However, cartridge loading requires you to put a little more pressure than suction loading. And, it is a comparatively expensive grease loading method.

  • Portability & Size

Not all grease guns come in the same size and weight. Lubricating guns used for the commercial purpose might be heavy-duty and bulky. For personal use, hand-operated pistol grip or liver action grease guns are easy to handle.

When you need to move from one place to another with your lubricating gun for greasing purpose, a portable grease gun would be a convenient choice. The battery-powered cordless grease guns are compact, light-weight and portable.

  • Self-priming

Some advanced level lubricating guns are blessed with Self-priming feature. It can deliver lubricating oil with a continuous rate of flow. It not only makes the greasing process convenient but also assists in handling the gun quite easily. If you wanna keep a consistent control over the lubrication output choose a grease gun with auto speed trigger. 

  • Warranty

Any mechanical device can break down unexpectedly. So, it is wise to buy a lubricating gun which comes with a manufacturer warranty.
