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. 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. 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

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. 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. Threads are the ridges that wrap around the cylinder or cone and form a coil. There are six common different types of threads: Don’t mix old and new greases - use only the correct type of lubricant for the job and parts you’re working with 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

Make sure all threading, couplers and connections are closed tightly but don’t over-tighten as this can cause failures in pressure and flow

Before finding the right grease fitting, you must first determine what kind of grease fitting thread you will use. You can choose from several kinds of thread components available. The thread fittings are commonly used in the BSPP, BSPT, metric parallel, metric tapered, NPT/NPTF, and UN/UNF.Use label tags to help you remember the type of grease the flows through each of your grease fittings. 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! 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. Manufactured according to DIN 3405, European standards or with reference to International standards, made of steel, case hardened, zinc plated and passivated. Various types for special purposes also available in brass or stainless steel V2A. Straight version (180°), according to DIN 3405 with cylindrical thread. Angled version is 45°, according to DIN 3405 or 90°, according to DIN 3405 with conical/tapered thread. D1 Straight

A grease fitting, sometimes called a Zerk fitting, grease nipple, or Alemite fitting is a small metal fixture used on mechanical assemblies. It provides lubrication to internal parts without leaks or overspill. Adding lubricants to mechanical systems helps improve their efficiency. Most grease fittings are made of zinc-plated steel, stainless steel, carbon steel, mild steel, or brass. Some variations also have a supplemental coating of chromate to limit corrosion and improve durability. Grease fitting thread identification Types of grease fitting threadsNearly 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.

Use a clean rag to wipe your fitting before installing it. A lint-free cloth would be the best for this job. 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)

Did you know?

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. 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 After determining your fitting thread, then you can now choose from the many different kinds of grease fittings, according to each of their particular features. There are also various types of grease guns to use alongside grease fittings, including the lever, pistol-grip, pneumatic, and cordless guns. Most of these guns are appropriate to use for any application. Always clean up any spillages immediately as grease left around on surfaces and floors can be a hazard
