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 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 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 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 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. Grease fitting gauge – the easiest method to determine the thread on a grease fitting The standard features of any grease gun tool - triggers, hoses and so on - tend to be fairly consistent across the full range of options for different formats and models. In other words, nearly all the different types of grease guns look fairly similar, regardless of whether they’re entirely manual, air-fed, battery-powered, or operated with a hand pump mechanism. This special tool helps save time and grants a simple way to distinguish one grease fitting thread from another. It includes the standard metric sizes such as the UNF, the American standard, the British standard, and many more. Without a grease fitting gauge 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.

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. Grease fittings are set in place by a threaded connection. Inside the fitting, a small captive bearing ball is pushed against a retaining spring by the grease gun’s pressure.
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 grease fittings remain closed until the pressure from the grease gun opens them to dispense grease into the system’s moving parts, greatly reducing the possibilities of machinery failure. Design 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) Always clean up any spillages immediately as grease left around on surfaces and floors can be a hazard Any item not in its original condition, is damaged or missing parts for reasons not due to our errorLever 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 Although having a grease fitting thread gauge is convenient, you can still identify the correct grease fitting thread through various ways without needing this tool. 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. Make sure all threading, couplers and connections are closed tightly but don’t over-tighten as this can cause failures in pressure and flow 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.
Grease fittings are small metal devices installed in various mechanical systems to facilitate the application of lubricants, typically grease, to moving parts. These fittings provide a point of access for injecting lubricants into components like bearings, joints, and other friction-prone areas. By regularly greasing these parts, friction and wear are minimised, ultimately extending the lifespan of the machinery. 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. Several types of goods are exempt from being returned.

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. 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
