Grease fittings offer us an easier way to keep machinery in good condition. However, we should also do our due diligence in finding the best ones for our needs. Therefore, you need to keep in mind the type of thread you need, your options, and correct their application. The fittings have been hardened to 85-88 HR15N, but the lip appears to have been subsequently softened to make it easier to fold over to retain the spring. (The end of the fitting is discouloured suggesting heat has been applied) This could also soften the first threads which could affect the fittings’ ability to start forming a thread in a hole. Use the lower jaw of your calliper to measure the external diameter of your grease fitting. The diameter of your grease fitting would be the point where the 0 (zero) mark of your calliper’s slider is pointed at. Types and sizes of grease fittings 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. More importantly, keeping your grease fitting in its tip-top shape will help maintain its effectiveness. Doing so will also help you save a ton of money in the long run. Here are some tips on how you can properly maintain your grease fitting.
Make sure all threading, couplers and connections are closed tightly but don’t over-tighten as this can cause failures in pressure and flow Manufactured according to DIN 3404, European standards or with reference to International standards, made of steel, case hardened, zinc plated and passivated. Some types are available in brass or stainless steel V2A. Double Hexagon Button Use label tags to help you remember the type of grease the flows through each of your grease fittings. 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.There are several common formats for grease fittings, with the most common being a standard-sized convex shape that fits snugly against the typical concave end of a grease gun nozzle. This combination allows the grease gun to be attached easily from various angles and still make an air-tight connection, meaning fewer instances of lubricant oozing out around the outsides of the grease nipple rather than being forced into the voids as intended. Various types for special purposes are also available in brass or stainless steel V2A.Hydraulic type lubricating nipples have a tapered thread. The head diameter is 6.5-0.2 mm (0.256"-0.008") H1 Straight Grease nipples, also known as grease fittings or Zerk fittings, play a crucial role in machinery maintenance by ensuring that moving parts receive the lubrication they need for optimal performance. In this article, we will delve into what grease fittings are, their importance, and how they contribute to the longevity of mechanical components.
When the fittings were high-pressure grease tested at 8,000psi (which is the pressure that Kingfisher test at) both springs collapsed. This is a critical failure. Threads are the ridges that wrap around the cylinder or cone and form a coil. There are six common different types of threads: Manufactured according to DIN 71412, European standards or with reference to International standards (ISO 3799, ISO 6392) and made of steel, case hardened, zinc plated and passivated. Using a specific tool called grease fitting thread gauge is the easiest method to determine the thread on a grease fitting.

In conclusion, grease nipples are indispensable components in the realm of machinery maintenance and functionality. Regular and proper lubrication through these fittings is essential for preventing wear, reducing friction, and ensuring the smooth operation of mechanical systems. Therefore, reducing the energy required for machines to function at their required levels of performance. Implementing a proactive greasing schedule with the use of grease fittings can lead to increased efficiency, decreased downtime, and ultimately, significant cost savings in the long run. As a vital aspect of protective maintenance, grease nipples require attention during selection to keep the machinery running smoothly and reliably.
There are many types of grease fitting threads available for use. But how can you be certain about the functionality of your grease fitting thread assembly? Let’s learn how to identify common thread types and how to choose the best for your application!Pneumatic grease guns - Air-powered models that attach to a compressor via a length of hose, offering greater power for industrial or larger commercial applications
Inspect the following if the grease fitting won’t take grease: If the fitting nipple is damaged, replace the fitting. But if the fitting is not damaged, it is obscured by debris that prevents the flow, and you should replace the fitting. If there seems to be no damage, then use an impact fitting cleaner to break down the clogs with compressed fluid chemically.Any item not in its original condition, is damaged or missing parts for reasons not due to our error A caliper tool is handy for measuring the thread diameter of your grease fitting. In addition, it is a simple two-part tool that can measure the internal and external diameters of objects. Measure the internal and external diameters of grease fittings with a calliper
