Hydraulic Fittings are designed to handle high pressures and resist corrosion in harsh environments. They come in various shapes and sizes, ensuring they will suit your needs.
You can choose between metal, stainless steel, or plastic fittings. The best material will depend on the type of hydraulic fluid you use, operating conditions, and environmental factors that could cause corrosion.
Strength and Durability
Hydraulic fittings must be strong and durable to handle the high-pressure environments of hydraulic systems safely. They must also be corrosion-resistant to prevent damage from the hydraulic fluid inside the hose. The most common metals in hydraulic fittings include carbon steel, stainless steel, and brass.
The size of the hydraulic fitting depends on the piping system and the type of vessel it connects to. The wrong size can cause the fitting to leak or not fit correctly, affecting the hose’s performance.
The most reliable hydraulic fittings are made of stainless steel and have excellent corrosion resistance. This will help protect the fittings from rust and corrosion, which extends their lifespan. They are also able to withstand the high temperatures found in hydraulic systems.
Easy Installation
Hydraulic push fittings can be installed quickly and easily without requiring specialized tools. They also feature a secure connection that prevents accidental disconnection.
In addition, hydraulic hose fittings typically outperform black pipes regarding both working and burst pressure ratings. If you’re concerned about how much pressure a particular system is designed to handle, consult your supplier for more information.
Another critical aspect of hydraulic hose fittings is proper sizing. A fitting that is too large or small will not connect or seal properly and may affect the hose’s performance. Hydraulic fittings are available in both inch and metric sizes and can be selected based on the measurement system of the equipment or hose. They can also incorporate additional features that provide other functionality for specific applications.
Less Corrosion
The metals used to make hydraulic fittings must be resistant to the corrosive effects of the hydraulic fluid. They must also be able to withstand the high pressures characteristic of hydraulic systems.
The most straightforward and economical hydraulic fittings are carbon steel. They are often used on equipment for industrial, agricultural, and construction hydraulic applications. They are durable and provide good strength at a low cost.
They are prone to corrosion because the tapered threads allow for leakage around them. Repeated assembly and disassembly exacerbate the problem. This is particularly true with forged steel fittings prone to cracking and seepage. These leaks can contaminate the system, leading to failure of components and hoses and safety issues for the people operating the machinery.
Lower Maintenance Costs
Nothing brings productivity to a screeching halt faster than a hydraulic system failure. The cost of repair lost production, and potential injuries to workers is a serious expense that can be avoided with regular monitoring of system performance, fluid analysis, and maintenance inspections.
Hydraulic fittings can be found in various materials, from brass and aluminum to stainless steel. Each offers unique advantages, but stainless steel is often preferred due to its strength, durability, and corrosion resistance.
When selecting a hydraulic hose or tubing fitting, ensure it has been rated to the operating pressures of your equipment and application. Tube and hose working pressure ratings are typically derated in harsh service environments or high temperatures. A hose swivel with a high-pressure rating is an ideal option for use with most hydraulic applications.
Reliability
Hydraulic systems use high pressures and must be able to handle the resulting forces. They also must resist corrosion from the hydraulic oil or fluid used in the system. This is why metals are more common than plastics in most hydraulic fittings.
All-metal fittings rely on metal-to-metal contact to hold pressure, while O-ring type fittings contain pressurized fluid by compressing an elastomeric seal between mating surfaces. Both fittings have a specific operating pressure range and require proper assembly procedures for a leak-free connection.
Inch compression and DIN metric bite-type fittings are susceptible to cracked flares from overaggressive wrenching. Still, the newer versions of these fittings have captured elastomeric seals on the mating surfaces for more excellent reliability. Those connections are reusable if you only need to connect a new hose.
