Nearly all lubricant applications via a grease gun involve a small device called a grease nipple or grease fitting, located on the body of the vehicle or equipment being lubricated. A grease nipple is a small metal fixture that functions as a valve cap, sitting over a grease hole on the exterior of a rotary bearing or similar moving part.
Grease guns can be adapted to each machine with different connectors, couplers and hoses to reach into tight spaces located centrally and out of reach. An important part of machine maintenance is the careful and precise application of lubricating grease. Over or under greasing mechanical components can cause a wide range of issues that include overheating, premature wear, and costly damage.Nevertheless, in spite of the above-mentioned benefits manual grease guns are best suited for cases when precision is not the critical issue. If this is your first foray into buying grease guns, you'll soon discover that there is no one single product on the market. For the uninitiated, it can seem a daunting prospect knowing which grease filling gun to buy, and having confidence that you are making the right decision. While it’s important to look after your gun, overuse of cleaners can cause damage Precision instruments
Make sure all threading, couplers and connections are closed tightly but don’t over-tighten as this can cause failures in pressure and flow A grease gun is an effective tool for moving grease to a point of application. The close fitting of the apertures ensures that lubricant is applied only where needed. Use it to improve your oil finish, revitalise weathered wood or make a completely new oil finish of a natural colour. A few spots simply applied by hand will fill the pores and produce a fine surface sheen to the wood. Napier Super VP90 total corrosion sachet– protection for guns and metal objectsA combination of salt, moisture and warmth (even the warmth in your car compared to that outside) is a deadly formula for encouraging rust.
Fundamentally, a grease gun is a hand-held pumping device that delivers lubricating grease into rotary bearings and other mechanical parts that are located deep inside machinery. They do an essential job in ensuring the smooth operation of moving parts and maintaining the optimum health of a machine. Grease guns are typified by their operation, with each offering its own benefits. The best choice depends solely on the type of application required and the preference of the user. Lever grease guns - Also called manual grease guns, this type is operated via a simple pressure trigger mechanism, enabling the user to control force and flow rate through their own physical squeezing force If you’re using a different grease than before, you’ll need to pump a small quantity of the new lubricant out through the nozzle of the grease gun until none of the old grease is left inside

As well as having a grip and a nozzle or ‘barrel’ of sorts, grease guns are typically operated via a lever that may somewhat resemble a large ‘trigger’. In certain newer or more automated models, this lever may be significantly smaller than in more traditional manually operated formats, giving rise to terms like ‘pistol style’ grease pumps. Pneumatic grease guns differ in weight, lubrication rate and working pressure. Prevention of oil spills is another advantage of pneumatic grease guns. This relates to their ability to doze the adequate material amount needed for a particular application. Thus, these tools are best suited for more precise tasks where high pressure is not required. Also, you shouldn’t forget that operation of these units is possible only when an air compressor is available. Always wear protective safety glasses and gloves when using grease guns, as the lubricant will be highly pressurised In aiming to better understand how a grease gun works, people may wonder why it’s called a grease gun in the first place. The simple answer is that the tool’s shape and basic mechanisms give rise to the name.
Lever Grease Gun -One of the most popular varieties of grease guns is the lever-operated type. Simply pulling the lever will create enough pressure to force the grease from the gun so that it can be applied to the relevant areas. Varying the length of the lever stroke will enable you to adjust the amount of grease that is dispensed Output - The amount of grease delivered with each pump varies in different guns. Understanding the amount needed for each machine can help to ensure that you don't over or under grease machinery and cause damage to seals and motors. Battery-powered grease guns - The core mechanism of battery-powered grease guns is similar to the above models, except that the on-board batteries provide the power to create the required pressure build-up (rather than the user having to do so manually or via external means) Such options would be more preferable in terms of overall convenience and greater portability compared with the pneumatic counterparts. It goes without saying that you will spend more money on one of the advanced battery-powered options, but it is surely worth the cost. The Ryobi R18GG-0 ONE+ Cordless Grease Gun is a right case in point. Some products, for example those from Napier of London — used by both Purdey and Westley Richards — also incorporate additives specifically formulated to protect your gun. The best gun oil list 1.

Types of grease guns | Comparison and recommendations
Functionality of mechanical tools mainly differs in volume and working pressure. The larger the volume is, the longer you will use the gun with the single grease filling. The pressure determines the feed rate of the material. The higher the pressure is, the more grease will be dosed. In general, these units are capable of building a decent amount of pressure (up to 7,000 PSI). For instance, Bravex Heavy Duty Professional Pistol Grip Grease Gun is capable of delivering up to 6,000 PSI which makes it suitable for various general purpose and professional grade applications including automotive, agricultural, marine, etc.
