Proper lubrication through grease fittings also helps in preventing corrosion, rust, and contamination of moving components. This is especially important in harsh environments or applications exposed to moisture and debris. By regularly applying grease through these fittings, machinery owners can significantly reduce the risk of premature component failure and costly repairs. Discover what can happen when you use a faulty or poor quality grease fitting here. 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 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

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. 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. 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 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.

Don’t mix old and new greases - use only the correct type of lubricant for the job and parts you’re working with Use a clean rag to wipe your fitting before installing it. A lint-free cloth would be the best for this job. 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. 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. 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

The fittings were grease tested, the opening pressures were 60, 70 and 240psi which is a wide range indicating inconsistent manufacture and 60/70psi is rather low for a hydraulic fitting. 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 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. 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.
